Where to dig?

 

[tom]

you use virtio? make sure you latest drivers inside your windows.

and post VM config setting, output of:

qm config VMI

No, i use rtl8139.
The problems started after updating to the latest kernel.
On 2.1 and 2.2 from iso all worked stable.

acpi: 1
boot: cd
bootdisk: ide0
cores: 2
cpu: host
cpuunits: 50
freeze: 0
ide0: local:114/vm-114-disk-1.raw
ide2: none,media=cdrom
kvm: 1
memory: 3584
name: terminal
net0: rtl8139=C6:44:9E:10:1C:52,bridge=vmbr0
ostype: w2k8
sockets: 2
tablet: 0

Problem only with windows server 2008. 2003 and Linux - no problem

 

[tom]

change the cpu type from 'host' to 'kvm64', and try e1000 instead of rtl.

 

[nik-weter]

I change the cpu end network adapter. Today there was no failure. I will watch.

got the same issue but also in linux.

only migration to another node, fixes the problem.
