VMotion and CPU Identification Mask problems

[Frans_P]

Hi everyone,

We have three ESX servers running:

- two HP Proliant DL385 G1 servers

- one HP Proliant DL385 G2 server

When migrating a running VM using VMotion the following message appears: The CPU of the host is incompatible with the cpu feature requirements of virtual machine; problem detected at CPUID level 0x80000001 register 'edx'.

I was told i should edit the VM, press Options, on the left pane press Advanced and select "Hide the Nx flag frmo guest" option and then i should be able to use VMotion but.... no difference. The error message is still there.

Anyone with an idea?

Regards,

Joris Kemperman

Also, this link is pretty helpful from HP

Check this article:

Since you are using AMD processors, you may need to set an additional mask on the vm to hide the execute disable (NX) flag.

Good Catch!! I didn't see the "5" at the end... I just saw HP and assumed Intel! Thanks!

Hi,

How many CPU's do you have in the G1. If your VM is 2 vCPU and the server has 1 CPU you may need to add a CPU to make things right.

There are some models that came with single core Opteron's.

As well there is a flag to support Dual cores which the G2 will have.
