Windows 2008 R2 + HOST CPU = BSOD

[longhair]

When ever I try to use the host cpu Intel Xeon X5770 with Windows Server 2008 R2, I get a BSOD. The problem is with Proxmox because I am able to install Windows 2008 R2 on bare metal and have no issues at all.

Can you post the BSOD details? What CPU type do you have set for the VM? Have you tried different ones?

 

[wahmed]

Also what other configuration did you use for the VM such as allocated memory, fixed or dynamic? Are you trying to fresh install Windows 2008 in the VM?

BSOD error is a 0x00000001E

The only CPU that works is the Default (kvm64) - everything else blue screens.

12 to 24 GB dynamic memory / 24 GB fixed, clean install with a new VM using setup disc - not cloned or template.

I can set up a VM using the default, change the CPU to host (or anything else for that mater), start it up only to see it blue screen. Shutdown, change back to default and it works like nothing was wrong.

What is the reason you can't just use the kvm64 CPU?

Have you tried with kernel: 3.10.0-8-pve/3.10.0-9-pve(updated yesterday)?

Very poor performance with the VM. Trying to figure out the root cause.

Have you tried with kernel: 3.10.0-8-pve/3.10.0-9-pve(updated yesterday)?

No, where do I get the updated kernel at?

Hi,

you should try to choose a vcpu model which match your physical cpu host (ivybridge, sandybridge,....).

You should have same performance than HOST, but the working cpu flags are tested and validated in this case.


(From my opinion, HOST should never be used)

I've tried that (Nehalem) and it BSOD with the same 0x00000001E error.
