Windows XP Guest switched off

[udo]

Hello,
we try proxmox-ve since january and most runs very well.
But we have two window xp clients for generating pdf-files via a networkstream (helios pdf-handshake in conjunction with acrobat) on a proxmox ve-cluster (2 nodes).
The windows-clients have partially a high load and under unknown circumstances the kvm-guest breaks. Just as switched off. After power on, all runs fine till the next crash occur. Some time the machine work for two days but often we have to start the machine some times a day. This happens on both nodes in the cluster.
The same image (converted) runs without problems on a ESX Virtual Infrastructure (same hardware as node 1).
Also runs one client since four days without trouble under kvm on a ubuntu8.10-box (same hardware as node 2) with following command:

kvm -m 1024 -net nic -net tap,ifname=tap0 -vnc 127.0.0.1:1 -hdb vm-103-disk-1.qcow2 -hda vm-103-disk.qcow2

The proxmox ve version ist up to date. One different between the ubuntu-kvm and the proxmox-cluster is the network-config. On the ubuntu i have only one bridge and on the proxmox-nodes bridges on vlan-tagging (but on node 2 is the used network directly bridged to one interface like on the ubuntu-box).

Other windowsclients (without big load) runs without problems since months...

Has anybody a hint?

Best regards

Udo

I assume its related to virtio. I suggest you switch to e1000 network card, most stable for windows guests (do not forget to use the latest drivers downloaded from intel web page).

Virtio in KVM-85 should be more stable also for windows guests, but we are still in testing here so no results yet.

This is related to some virtio network issues under severe traffic ( i can be slow traffic but always doing IO network, not necessary high load but the issues appear quicker) .

im waiting a new version of virtio drivers for more test.

Hey,
both machines are running now with the e1000-driver since two hours.
Its to early to say anything definitely but i'm hopefull.

Good news,
with the e1000-driver the xp-clients are stable! Very good...
