NOT_IMPLEMENTED vmcore/vmm/cpu/fpu.c:452

I am trying to run ESXi on a lab box.  I was not able to install 5.5 (purple screen of death during install), but was able to install 5.1.  Now, in the vSphere client when I configure any VM to boot from an ISO (I've tried Win XP and CentOS Linux) I get;

VMware ESX unrecoverable error: (vcpu-0) vcpu-0:NOT_IMPLEMENTED vmcore/vmm/cpu/fpu.c:452

The ESXi box has an AMD A4 CPU.  The ISOs are uploaded in the datastore.  My client machine has VMWare Workstation 9 on it and that works fine (probably irrelevant, but just mentioning in case there is some conflict).

Any ideas?  I wasn't coming up with much via google.  Is this saying there is some sort of issue with FPU virtualization and the A4 and/or chipset on the box?  AS far as I can tell, the A4 supports AMD's virtualization technologies.

Are you running ESXi 5.5 nested under Workstation 9?

No.  (I had a different issue trying to use ESXi 5.1 under Workstation 9 on a different machine).  The ESXi server is installed and running on the separate box with the AMD A4 cpu.  I get this error when trying to create any VM on that box from the vSphere client.  The error appears as the VM tries to boot to an iso in the datastore.  Again, I doubt there is any issue with running Workstation 9 and vSphere Client 5.1 on the same box but I just thought I would mention it.

Hi,

you got anything new on this? I tried to install esxi 5.1 u1 on a zotac zbox nano aq01 plus(which uses an AMD A4-5000 CPU). When trying to start a virtual machine, i get the following error: VMware ESX unrecoverable error: (vcpu-0) vcpu-0:NOT_IMPLEMENTED vmcore/vmm/cpu/fpu.c:452

Does anybody know something about this error?

Hi,

I'm having the same issue with a AMD Athlon 5350 (AM1 socket).

Anyone found a fix?

Cheers,

As a workaround, I believe you can explicitly specify AMD-V/RVI as the preferred execution mode for the affected VMs.

I've tried under Edit Settings - Options - CPU/MMU Virtualisation

With all the options, with no luck. Is there anywhere else that this might impact?

Thanks,

This is a long shot, but you can try adding the following to /etc/vmware/config on the host:

featMask.mockup.cpuid.XSAVEOPT = "Val:0"

Please post your vmware.log file.

Bummer.  It doesn't look like that feature is maskable in ESX 5.1.

If you can survive without AVX, you could try the following:

featMask.mockup.cpuid.NUMLEVELS = Val:0xb

featMask.mockup.cpuid.AVX = Val:0

featMask.mockup.cpuid.XSAVE = Val:0
