Hi,
the only place I know that is mentioned is in the Nutanix AHV Best Practice Guide but the figures are pretty much the same.

thanks

Thank you for your insightful post. following questions:

can we have something like this for AHV?
I am sizing a generic workload with 3:1 (vCPU:pCore)?

In reply to magander3. I dont want to edit the vmx file, I would prefer any esxcli or vim-cmd kind of commands to do the same. Thanks for the help.

In reply to Rahul. do you need to perform the action from within the ESXi? If so you could edit the VM .vmx file but that requires the VM to be powered off and powered on. thanks

In reply to magander3. Thanks for the quick reply. Can I use esxi based cli (ssh to esxi and run some command there?).

Hi,
Thanks. Yes you can use PowerCLI and the set-vm cmdlet. See https://www.vmware.com/support/developer/PowerCLI/PowerCLI55/html/Set-VM.html?vmw_so_vex_mande_12

Hi,
This is a great post!!
are you aware of how to modify CPU’s for a particular VM via cli?
I can do it via vsphere, but cli would be awesome!
Thanks in advance

[…] vSphere VM vCPU to ESXi host CPU core allocation – Magnus Andersson, a VCDX, writes up a great post on the topic of vCPU to pCPU relationships, including a script to calculate the oversubscription ratios and create an HTML report. That’s awesome! […]
