Hello everybody,

I`ve got a problem with Windows XP VM on Proxmox.

During work on the VM it randomly crashes and shows very often different BSODs. (i.e. 0x1000000a)

Reconfiguring the VM from 2 Cores/Socket to 1 Cores/Socket did solve this problem. But Im not satisfied with this solution. Maybe you could give me a hint how to fix this issue?

Here are some information from the mainpage:

Version (package/version/build) pve-manager/1.5/4660
Kernel Version Linux 2.6.32-1-pve #1 SMP Fri Jan 15 11:37:39 CET 2010

Thanks for your help.

post the output of 'pveversion -v', your are not using the latest version.

(I suggest you move to pvetest repository to test the latest kvm (we also plan to upload a new 2.6.32 this week))
 
Heres the output of pveversion -v:

pve-qemu-kvm: 0.11.1-2

But Ive got a newer host system that has this this problem too. Here the pveversion of that hostsystem:

pve-manager: 1.5-10 (pve-manager/1.5/4822)
running kernel: 2.6.32-2-pve
proxmox-ve-2.6.32: 1.5-7

vncterm: 0.9-2
vzctl: 3.0.23-1pve11
vzdump: 1.2-5

vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.4-1
ksm-control-daemon: 1.0-3

These machines are working productive so I dont know if its that good to use the latest pvetest kvm.

But thanks so far.

So you want me to test the 'pvetest' repository? Is there a possible fix included?

Thank you.
 
there is the latest KVM - and yes, pls test the 2.6.32 Kernel.
 
Hi,
I have the same problem and pvetest didn't fix the error.
I only have it on a server with an 2 Xeon(R) CPU X5560. on my test server with i7 CPU 920 there no BSOD with the same Virtual Maschine.

best regards

post the config from your windows guest, see /etc/qemu-server/VMID.conf
 
Here is the config: 114.conf

Thanks

any special reason why you use scsi for disks? the general rule for windows is IDE and raw format - best tested and widely used.
 
for scsi there was no special reason, but for qcow2 there i can make snapshots. now i changed the vm to ide.
 
I got the same kind of troubles with a Win2k8 x64...
I've tried in VIRTIO and IDE : same error 0x0000000a
My storage is on iSCSI

but didn't try with 1 Core only...
(I should maybe open another post as far as it's on Win2k8?)

use latest version from pvetest, better?
 
tried also (from pvetest on Monday) => same problem
tried on a non-hyperthreaded machine also => idem

win32k.sys or ntkrlnmp.exe are the cause of the cras (says windbg)
 
Hi All,
i thing i found the problem.

I disabeled some Bios settings:
Intel SpeedStep
Intel C-State
C1E Support
Hardware Prefetcher
Adjacent Cache Line Prefetch
Execute-Disable Bit Capability

Now I enabeled the following setting and wait if the error came back:
C1E Support
Hardware Prefetcher
Adjacent Cache Line Prefetch

A nice side effect is the my average load fall from 0,35 to 0,15.

Regards
 
Hello gunforce,

thanks for your answer.

So by disabling:

Intel SpeedStep
Intel C-State
Execute-Disable Bit Capability

The problem is fixed?

disabling the following fixed the problem.

Intel SpeedStep
Intel C-State
C1E Support
Hardware Prefetcher
Adjacent Cache Line Prefetch
Execute-Disable Bit Capability

I had 4 days with no error. now i try to enable the settings, but i need some days to see if the error came back.

Regards
 
Hi All,

1. Test
C1E Support > enabled
Hardware Prefetcher > enabled
Adjacent Cache Line Prefetch > enabled
Intel C-State > disabled
2 Day Withou Error but slow again average load 0.35

2. Test
Hardware Prefetcher > enabled
Adjacent Cache Line Prefetch > enabled
C1E Support > disabled
Intel C-State > disabled
average load was back to 0.10
4 Days without errors

3. Test
Hardware Prefetcher > enabled
Adjacent Cache Line Prefetch > enabled
C1E Support > disabled
Intel SpeedStep with TurboMode > enabled
Intel C-State > disabled
2 Days without errors

Now i stop testing.

Result:
C1E Support > disabled
Intel C-State > disabled

Regards
