I plan to remove around 600GB of snapshot VM but I worry about VM's effect.

• I heard about VM stun or can't access via network during removing process.
  • How serious is it?
    • VM will stun always till remove complete or unpredictable.

Anyone have experience , please share with me.

Thank you

Product/Version : vRealize Operations Manager/6.7

Question :

Do the new Capacity reposts and analysis take into account HA + Buffers.  I cannot find anywhere to check if it does.  It was visible in the old policies

Hi everybody!

We are trying the new version of vmware vRops 6.7 and there are some metric compared with the previous version that are very confuse, one of them is the "memory usage".

In vRops 6.6 the metric "memory usage" is the "guest memory", that's ok. Now you read the release notes about 6.7

"

The Memory|Usage (%) metric of Virtual Machines considers memory usage from Guest OS perspective and not from hypervisor perspective.

In previous releases, the Memory|Usage (%) metric of virtual machines referred to the amount of memory that is actively used, as estimated by VMkernel based

on recently touched memory pages.

This was different from what you would see inside the Guest OS as a memory usage.

The formula of metric Memory|Usage (%) is now changed to (Memory|Utilization (KB) / Memory|Total Capacity (KB)) * 100.  Here the newly introduced Memory|Utilization (KB) metric depends on the Guest OS metric,

which is provided through VMware Tools, and is available since vCenter Server 6.0 Update 1, ESXi 6.0 Update

"

One example comparing vROPSa 6.6 and 6.7 in my enviroment

I have a VM1 with 16384 MB Ram Memory Size

VM1--> vROPS 6.6

Memory usage-->21.79 %

Memory recommendation size--> 7413 MB RAM

Active guest memory-->3768 RAM

VM1-> vROPS 6.7

Memory usage-->87.54 %

Memory recommendation size--> 16777 MB RAM

Active guest memory-->3768 RAM

will this be the topic? Because the are a lot of difference between 7,4 GB and 16 GB in recommendations terms. I have to purchase a new hardware....

Best regards

Hello,

when I launch a vmcreation test on vsan, every time the timeout is reached the vm is not removed is that expected?

because we have to remove vms manually after that

regards

I don't know how to write the latest version of VMware Console.

Is there an example for me to refer to?

I don't know how to generate the webmksTicket parameter?

Release Notes

Thank you very much!!!

Good Morning,

we have six ESXi 6.0 hosts (Enterpris Plus) running and (during normal operations) we have enough RAM in these machines service the configured ram of all VMs without ballooing or paging on the ESXi level.

There are several artices regarding page file size out in the internet e.g.

https://social.technet.microsoft.com/wiki/contents/articles/13383.best-practices-for-page-file-and-minimum-drive-size-fo…

Page File – The definitive guide – Windows Security

Most of them seem to be for physical machines and dont's say much about servers in virtual environments.

As I have seen that some of my VMs are using the page file (and do disk I/O down to the SAN) although they have still virtual memory free I wonder whether I should switch off/reduce the size of the page file of the VM and leave the memory handling to the ESXi hosts (plenty of physical memory, if necessary memory ballooning and ESXi pagefile). Depending on the VM I could also increase the virtual memory of the VM to some amount.

Are there any best practices or recommendations for this? Anything official from VMWare and/or Microsoft? Are there any differences regarding Windows Server 2008R2 / Windows Server 2012 R2 / Windows Server 2016 (and Linux)?

We have just setup vRLCM 1.2 and are having a real PITA getting My VMware downloads to work behind a proxy.

It can communicate with the downloads site, but the downloads fail.

and of course, we can download via a browser behind the proxy.

We did already try this post, without success.

Problem with vRealize Suite Lifecycle Manager proxy settings

Is there a way to manually update vRLCM with the updated product binaries we pull down ourselves, then upload to the appliance?

Would be nice to see the steps for this, as we have other deployments on isolated networks that we would also like to use vRLCM on.

Thanks in advance for any input.

Hello Everyone, 

I  have a task to remove tags of VMs that could reside in any of two vCenter servers and before I remove I have to get the list of current tags they have.  Something that could  collect the list of VMs from CSV and export with TAG info and I can run another script to remove Tags or may be both in one.

Thank you very much.  

Hi to all,

inside the Windows VM, sometimes when I strike Ctrl+c, some seconds after I release the key combination it results in typing repeatedly "cccccccccccccc..." or after having struck Ctrl+v it results in "vvvvvvvvvvvvvvvvvvvvv..." and it doesn't stop until I press another key. It happens with the delete key or the tab key, too.

This happens very frequently (an average of once every 2 - 3 minutes, but it can happen twice in a minute or more) but randomly and in combination with a "special key" (i.e. Ctrl, Delete, End, Backslash, etc.) and is VERY, VERY annoying.

Almost every time that this happens, I noticed that when I press the ESC key, it opens up the Windows Start Menu.

To "re-enable" a (temporary) correct working state of the keyboard, I have to repeatedly press ESC, then repeatedly press CTRL, then repeatedly press the Windows key, then repeatedly press the ALT key. After that, I can continue working for a couple of minutes befor it happens again

It started happening as I upgraded to High Sierra (from El Capitan) and to Fusion 10.0.0 (and it's upgrade to 10.0.1) from fusion 8.x.

I later downgraded to Fusion 8.5.8 (ev. upgraded to 8.5.9) to resolve the CAPS LOCK issue, but this one remained, unfortunately.

In the meantime I have upgraded Windows 10 on both my VMs to version 1709 (OS build 16299.64) from Version 1703 (OS build 15063.674), but the issue remains.

This is making me NUTS, I cannot work anymore and I am a bit desperate.

This issue seems only to happen inside the VMs, not in the Mac host.

I already tried switching keyboard with a Mac one (usb), but the problem stays the same.

I already tried uninstalling and reinstalling last version of vmware Tools, with no success

I already tried searching on the internet for a solution, but until now, no tweak has worked for me.

Can someone help me, please?

Info:

Mac (27-inch, Late 2013), 3.4 GHz Intel Core i5, 32 GB 1600 MHz DDR3

Osx: 10.13.1 High Sierra

Fusion: 8.5.9 (7098239)

VM: Windows 10, Version 1709 (OS build 16299.64)

Hello vmWare community,

Please note, I have placed all of the config information at the end of this post so I can jump right into the issue discussion.

Basically, the situation is that at certain times, when one VM (VM-bad) becomes highly active, the CPU utilization on another VM (VM-good) climbs despite not having any additional load.  In extreme situations, the CPU load on VM-good gets so high as to incur a DoS event and traffic through VM-good ceases.  VM-good does eventually recover but only after VM-bad has calmed down.  The issue is intermittent in nature and only seems to occur when VM-bad is booting or at other select periods of high-activity.

After much troubleshooting and stat collection (using esxtop --> CSV files; parsed w/ perfmon), it appears that disk access\utilization is the root cause.  I say this because the stats paint a picture of very high IOPS (peak > 150) and long read\write times (peak > 2500ms) for both VMs.  The core apps running on VM-bad require near constant disk access due to it performing full packet capture as well as pretty constant updates to several mySQL databases.  Now I'm sure those reading this are thinking "Well DUH - yeah, that's your issue" and I'm pretty sure I don't disagree but I do have some questions re: how ESXi handles shared resources and where my expectations are inaccurate.

Additionally, I think I was able to validate this as being a disk access issue because after migrating the packet capture destination and mySQL databases to a second mechanical HDD, VM-good's CPU utilization and DoS issues seem to have pretty much gone away.  Even when VM-bad's disk latency times run high (i.e. 600+ ms), CPU utilization on VM-good remains nearly constant and packets flow unimpeded.  I have not captured a new set of esxtop stats post-migration but I may if VM-good starts acting up again.

As an aside, prior to above-mentioned migration, I did tinker with the various tuning options such as IOPS, CPU allocation (both p- and v- CPUs), CPU cycles, etc.  None of those seemed to help.  However, if considering this in the context of the suspected root cause (disk latency), this probably makes sense.  My belief is that most disk latency issues - and especially those in ESXi - are not really solved as much by tuning as they are by adding more spindles, SSDs, or implementing RAID (i.e. RAID 10 or 0).

So, with all of the above as backstory, what I'm really looking for here is some clarification and validation\correction about my findings & expectations:

1. Overall, does it make sense for high-activity in one VM to directly cause a measurable CPU utilization increase in a different VM?  I think it does if I'm correct about disk latency being the root cause but need some validation and\or elaboration here.
2. If #1 does make sense, I expected at least some improvement by tuning the VMs via IOPS, etc. reservation and\or limitation but none of those seemed to have any real effect at all...but maybe this is expected if the root cause is disk latency.
3. Also, despite VM-bad's high resource demands, I expected ESXi to do a better job balancing the load & resources especially given how much overhead this system has (please see specs below for more details).  But based on my observations & testing, it appears my expectation was inaccurate so please fill me in here.
4. My theory on why there is a directly measurable CPU utilization increase on VM-good is that, due to increased disk latency, VM-good's CPU is getting bogged down by having to mange it's own set of resource issues such as buffers filling, etc.  Does this make sense?
5. But...if #4 does make sense, then why doesn't VM-bad also have issues???  That's part of what makes this kinda strange - the actual VM that is bogged down still gets it's own job done...packets are not dropped, packet capture is flawless, and the DBs all seem to have the expected set of data and do not get corrupted.
6. Finally, if the root cause is disk latency, is there any other tuning that can be done in order to not require the disk migration I performed?  I am pretty sure the answer is no and that more spindles, faster drives, RAID, etc. are the only true remedies to disk latency issues.

Please comment where appropriate and thanks in advance for taking the time to read and respond.

Does esx support standard shell scripting statements (for example -for name in `cat /etc/hosts | awk '{print $2}'`) type of syntax?

What I am trying to do is create a script that will get a list of all running VM's on the host, then shut them down using vim-cmd command or do I have to use power-cli commands and forget shell scripting commands? Any help or suggestions are all welcome (even smart ass remarks.. )

Hello.

I've a problem - install esxi 6.5 on Supermicro X8DT3 and it work fine, except terrible fans noise. Its run over 16000 RPM.

From IPMI:

The same data in BIOS.

But in esxi:

So it look like wrong sensors data reading in esxi.

I'm update BIOS and IPMI to the last available version. Set Energy Save Mode in Bios and in Esxi. Set in ipmi thresholds for fans to 10000 RPM:

But fans still scream. 

May be someone know what to do?

p.s. sorry for my poor english

I attempted to complete the wizard but something is wrong. I added my vCenter, but status for the collector says there are no vCenter servers added.  When I try to add it I get a message that states it is already added.

                            Your collector has no vCenter or NSX Managers configured. Go to Settings to add one.

Adding the vCenter:

                              The certificate provided by your vCenter is not valid (Certificate Thumbprint [2f03d7bc9697f8792e4ad772376b5c9fd5bc8564]). 
Press "CONTINUE" if you would like to continue using an invalid certificate.

then

                              An attempt has been made to add an endpoint that has already been added.

Rebooting the appliance just puts me back into the registration wizard. 

Your collector id is: 9b80495c-cb9e-3ff0-b120-ead03299bc4b

Should I re-deploy the virtual appliance and try again?

Hi,

How do i solve this error, was starting a new vm. @

I'm looking for a solution to enable end users of Windows virtual machines in a vSphere environment to update VMware tools on their own, they will have no access to the vSphere management layer.

I've seen reference  to using the vmware-toolbox-cmd command. Upon trying that I get the following error:

C:\Program Files\VMware\VMware Tools> .\VMwareToolboxCmd.exe upgrade status

A new version of VMware Tools is available.

C:\Program Files\VMware\VMware Tools> .\VMwareToolboxCmd.exe upgrade start

The host does not support auto upgrade of VMware Tools.

Any suggestions?

Many thanks

Anyone know how to login to the embedded vRealize Orchestrator - TCP 8281 (Embedded for Content Management) on the vRLCM appliance?  Trying to troubleshoot the Content Pipeline workflow

I already opened port 8281 and I get a vRO login prompt; but i dont know what user/creds to use.  I tried the default vRLCM user admin@localhost but that doesnt work

Hi,

I'm using vRA and vRO 7.4. All plugins have been installed and configured.vRA and vRO full integrated.

I have a blueprint and It has Custom Propery named VirtualMachine.Network0.ProfileName. It has a value like "External-Network-XXX"

I have created subscription and called a workflow when request life cycle state has VMPSMasterWorkflow32.Requested. I am getting all properties of this request with payload... It is very easy..

This workflow is doing something and when workflow is finished I want to update VirtualMachine.Network0.ProfileName value as "External-Network-YYY".  Then VM will be created on External-Network-YYY profile.

Because VM network profile needs to change  according to some circumstances ..

How to do this  ?

Trying to deploy an ovf fails due to an extra config where mem.hotadd is disabled on the example OVF/OVA and I'm using OVFTool 4.3.

OVFTool 4.2 does not error in the same fashion, using the same syntax (--allowExtraConfigs).

The two configs I see in the VM are:

<vmw:Config ovf:required="true" vmw:key="memoryHotAddEnabled" vmw:value="false"/>
<vmw:ExtraConfig ovf:required="true" vmw:key="mem.hotadd" vmw:value="false"/>

Hello,

We've built our first Linux based Horizon pool, we're able to log into the machines just fine using both Thin and Thick clients through the agent with Username and Password.  But now we're attempting to work toward token authentication via Thin Client.  I'm assuming that because this module cannot install we're having this issue as we know token login works in our non VDI environment.

On one of our test boxes we've been trying to install the Horizon Agent with the "-m yes" to install the Smart Card Redirection Module.  During the installation which does go through successfully it fails on the Smart Card module and gives this message.

Installation starting...

Failed to install smartcard redirection module, because the system doesn't meet the following requirement(s):

1, The host system should be RedHatEnterpriseWorkstation 6.6 64bit or later

2, The pcsclite verison should be 1.7.4 for installation or 6.2.0 for update.

After looking into this I checked versions just to verify...

cat /etc/redhat-release

Red Hat Enterprise Linux Workstation release 7.5 (Maipo)

lscpu

Architecture:          x86_64

CPU op-mode(s):        32-bit, 64-bit

rpm -qa | grep pcsc

pcsc-lite-ccid-1.4.10-13.el7.x86_64

pcsc-lite-libs-1.8.8-7.el7.x86_64

Any help on this issue would be much appreciated, we have a ticket open with VMware already, but we're still troubleshooting while waiting for responses and other guidance.  Thanks for your time.
