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: /usr/bin/kvm -monitor unix:/var/run/qemu-server/103.mon,server,nowait -vnc unix:/var/run/qemu-server/103.vnc,password -pidfile /var/run/qemu-server/103.pid -usbdevice tablet -name Seeclic_Web -smp 1 -id 103 -cpuunits 1000 -vga cirrus -tdf -localtime -k fr -drive file=/var/lib/vz/images/103/vm-103-disk-1.qcow2,if=ide,index=1 -drive file=/var/lib/vz/images/103/vm-103-disk.qcow2,if=ide,index=0,boot=on -drive file=/var/lib/vz/template/iso/NETKVM-20081229.iso,if=ide,index=2,media=cdrom -m 2048 -net tap,vlan=0,ifname=vmtab103i0,script=/var/lib/qemu-server/bridge-vlan0 -net nic,vlan=0,model=virtio,macaddr=26:57:C0:D4:E1:55 root@ns205568:~# uname -a Linux ns205568.ovh.net 2.6.24-2-pve #1 SMP PREEMPT Wed Jan 14 11:32:49 CET 2009 x86_64 GNU/Linux root@ns205568:~# pveversion -v pve-manager: 1.1-3 (pve-manager/1.1/3718) qemu-server: 1.0-7 pve-kernel: 2.6.24-5 pve-kvm: 83-1 pve-firmware: not correctly installed vncterm: 0.9-1 vzctl: 3.0.23-1pve1 vzdump: 1.1-1 vzprocps: 2.0.11-1dso2 vzquota: 3.0.11-1dso1 Phil Ten -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
