Re: delayed HDD activities after suspend

Hello Wila!

 

Thank you for your reply and suggestion.

 

After defragmentering both the guest and host I found that:

 

  1. first suspend was much faster (approx 30 sec) compared to several minutes (still not as fast as Win 7 VM)
  2. second time suspend, back to slooooow. Now again, taking several minutes with slow disk performance

 

Difference between VMs

 

One difference I noted between the fast suspending VM (Win 7) and the slow VM (Win 10) is that Win 7 VM uses only one vmdk file per drive, while Win 10 VM uses multiple vmdk files, each 4 GB (total 70 GB).

 

Magic VMX settings!?

 

After adding the settings below to the Win 10 VMX file the resume time and disk I/O performed normally. I found the same settings in the Win 7 VMX file. Don't understand what they do!? 

 

prefvmx.minVmMemPct = "100"

mainMem.useNamedFile = "FALSE"

mainMem.partialLazySave = "FALSE"

mainMem.partialLazyRestore = "FALSE"

 

 

It looks like performance is a constant concern when searching the net. I do not understand why VMWare isn't compiling this kind of important know how in some dokumentation? Now it seems to me we're all guessing ... (costly)

 

 

Again, thanks Wila !

Can you please navigate me to some bug report form? I seem to have overseen it.

 

Bug still occurs as of the new release 12.1.1, sadly.

VMWare Tools fails to install on Czech Windows 2000 & XP

Recently I've been reviving two installations, Windows 2000 SP4 and Windows XP SP3 (both czech versions), when I found out I am unable to install the latest VMWare tools.

 

Both systems were running the tools perfectly fine on older version of VMWare (probably 7 or 8) but updating to the latest tools on VMWare Workstation 12.1 failed. When the installation is almost done, the program starts to "roll back actions" and then says that the installation ended up prematurely. Same on 2000 and XP, but on Win2k there is an additional error regarding Think printer driver (but when I click continue on it, the installation continues "fine").

 

I have tried to reinstall Win2k multiple times, but I am always ending up in the same problem (I tried to install both before and after applying all updates), except for the English localization where the tools installed properly. Now I don't really understand why this don't work on Czech locale but works fine on the English one, since it has always been working on Czech too for many years.

 

Interestingly, the last versions that I found installable is 8.6.16-3054402 and 8.4.6 build385536 (quite an old old).

 

I've come across this KB article that appear to describe my problem, but according to it, it should have been fixed long time ago:

VMware KB:    VMware Tools installation in non-US-English 32-bit Windows rolls back and fails with MSI error status 160…

 

This is the log I found in the temp folder on Windows 2000 after trying to upgrade from the version named above:
http://pastebin.com/riWPa54G

 

Also, it is extremely disappointing that a product of such quality lacks 3D acceleration on Windows 95 and Windows 98 systems.

 

The bug is present on latest release: 12.1.1

 

Any help would be greatly appreciated.:)
Thanks.

Re: APD condition on some RDM LUNs

I am sure you know that your vSphere is End of support.

VMware KB: End of Availability and End of Support Life for ESX 4.x and VMware Management Assistant 1.0 and 4.0

 

Regarding the APD condition on ESX4 hosts, make sure the /vmfs/failopenifAPD is enabled to prevent other VMs having an impact(KB linked).

Unregister any unresponsive/inaccessible VMs and perform a rescan on host(we are expecting to clear up the dead paths hear)

 

VMware KB:    Virtual machines stop responding when any LUN on the host is in an all-paths-down (APD) condition

 

esxcfg-rescan -A

 

Please note if the host is a part of cluster, please migrate the VMs which are running fine to a different host to avoid any impact.

A host rescan in this situation can trigger a hostd issue if it is dormant now.

vFlash in 6.x

Hi All

 

We have now completed a roll out of 6.0 for all vCenters and ESXi hosts.

I'm becoming very interested in deploying vFlash for our SQL estate as we are now migrating them away from blades to Hosts which will have free drive bays.

 

However I have some questions.

 

With regard to the actual configuration of the HDD Should this be Raid-0 or a Raid-5 setup..?

As vFlash appears to be geared to improving the Read intensive parts of  an application (SQL in my case) would Read intensive (MLC) SSDs work best..?

For SQL would a block size of 64k or 8k work best as I believe SQL reads in 8K..?

Re: After successful shutdown, when it boots again I cannot connect?

So I re-installed ESXi for the 3rd time and started the setup of FreeNAS again. This time I wanted to narrow down even more. So I followed section "5. Create a Virtual Storage Network." and when I entered my private IP https://b3n.org/wp-content/uploads/2015/03/Image-12.png that is out of my DHCP server range and rebooted ESXi I could not connect?

Why is this?

Hi,

 

Hmm.. now that you highlight these settings, they do kind of remind me to something. Now sure how I missed that.

 

See:

http://sanbarrow.com/vmx/vmx-config-ini.html

 

VMware doesn't compile a list of .vmx settings because they are considered advanced usage and not meant to be fiddled with as it is so easy to end up shooting yourself in the foot.

It is good however that one can change the settings this easily.

 

There's also these KB articles:

http://kb.vmware.com/kb/2030543

VMware KB: Snapshot with virtual machine memory takes longer on an ESX/ESXi 4.x or 5.0 host

 

Thanks for reporting back what did fix your issue.

Re: Why cant I see hosts/guests in my vCenter while I can see them in the vSphere Web Client?

Thanks for the response.

 

I dont know what role my account has in vCenter due to the fact that I use vSphere Web Client to manage VM Hosts and thats about it.  Im not responsible for the admin of vCenter, which is done by another team.  However, as users of the platform, we want to understand what vCenter server contains our VM Hosts.

 

A Get-Inventory returns data!  I see 3 columns of data; Name, Type, ID, with the Type being either Folder, Datacenter, or VirtualMachine.  So now I can see some of the VirtualMachines, but I just dont see all the VirtualMachines.  It looks to me the virtual machines I see are owned by our team, so it looks like some type of permissioning is done so I can only see ours.

 

If we simply want a list of VM Hosts across VI Servers, Im assuming all we need is an account that has 'Read' rights to all VI Servers, correct?  Basically, what are the least privileges/role I need to display all VM Hosts? 

 

Thanks for the help.

your virtual switch doesn't have any uplink (VMNIC) attached with it.

Re: How to remove VM disk (using partitions)

You need to remove all the snapshots or the snapshots related with that disk to be able to delete the disk hisself. Example, even if you do not use it, if the disk was there when you did a snapshot, the related disk can't be removed.

Looks like it.

You will have to talk with the vCenter admin I guess.

Simplest would be to give you Read-Only View permissions on the vCenter, and let that permission propagate.

Out of curiosity, does this show the VMHostname ?

Issue installing ESXi on Hp Gen 8

Hi guys,

 

I'm hopping some one can shred some light on an issue I'm having.

 

I'm trying to install ESXi on my Gen8.

 

I have downloaded and installed ESXi on to a flash drive, everything goes ok however once the install is completed the server prompts a reboot. The reboot starts and goes through the BOIS when you would expect ESXi to boot for the first time the screen goes blank and the sever fan stops asif it goers in to stand by mode.

 

I have tried this on multiple Flash drives and a internal HDD.

 

I've checked all BOIS settings.

 

Attempted to install under MBR format.

 

Please can some one shred some light on this for me.

 

Thanks a mil.

 

Chris.

Site Recovery Manager

If I will be using Site Recovery Manager, Do I need to configure distributed switch on the DR site if the VMs from the production site are already using distributed switch.

If the vCenter Server and the server itself is using its own domain (not joined in the AD/vsphere.local), can I still install SRM and configure it or vCenter Server and its server should be joined to AD?
