Hello,

My kvm processes are exiting on what I think are VIRTIO errors:

Guest moved used index from 24543 to 24606

1) Network specific settings:

I am required to hide the Mac address of the kvm guest, therefore I added
the following line in /etc/network/interface on the host:

up route add -net GUEST_IP netmask 255.255.255.255 dev vmbr0

this routes the traffic via the host IP and therefore hides the guest IP address.

2) I replaced virtio by rtl8139 and had no problem so far.

Background:

I am running a proxmox 1.1 host hosted by OVH. I have kvm guests running
windows 2003 server SP2 with VIRTIO network. and unfortunately,
these guest are crashing after a few hours at the most.

virtio installed: NETKVM-20081229.iso

To gather more information, I launched kvm via a command line.
When the kvm process exit it output the error message :

Guest moved used index from 24543 to 24606

kvm cmd line:
