vSphere ESXi 6.x or 7.x on Intel x5660 CPU – Legacy CPU for vSphere 7 – Virtually That Guy

This is quick blog post about hack for running ESXi 7.0 on legacy CPU in my case x5660.

CPU_SUPPORT ERROR:
The CPU in this host is not supported by ESXi
7.0.0. Please refer to the VMware Compatibility Guide (VCG) for
the list of supported CPUs. 

It could be fix during boot by pressing SHIFT+ O and adding allowLegacyCPU=True to the cdRomBoot runeaseal

accept that the CPU might not be supported and proceed with install. With adding > allowLegacyCPU=True, the installer will convert an error to a warning.

Below is one of my hosts on vsphere 7.0 on intel x5660.

You can do via CLI

esxcli software sources profile list -d /vmfs/volumes/DEV-SSD-LUN-01/VMware-ESXi-7.0.0-15843807-depot.zip

esxcli software profile update -p ESXi-7.0.0-15843807-standard -d /vmfs/volumes/DEV-SSD-LUN-01/VMware-ESXi-7.0.0-15843807-depot.zip

Your commands offered for use with putty don’t work with legacy CPU’s. I’m guessing there is a switch to ignore warnings that isn’t being used.
