automatic reboot winxp hanging on vnc...

Hi all,

we are running an winxp client as kvm guest (with vnc option) all day long (license management software). So automatic windows updates are activated.

On MS patch days steadily the guest hangs on automatic reboot, until one connect with vnc to it. Instantly and without any user action the reboot takes place after that.

Is that a feature or a bug? Any hints to solve this problem?

Thanx in advance
Thomas

Strange.

What kvm version are you using?

Are you using -net user or -net tap?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Strange.

Ups, sorry for forgetting this: I am using kvm-52 in a productive environment. Host ist Debian etch, debs are self backported from unstable. Kernel version 2.6.22.9.

In two weeks I will have an testing system, so that I can probe newer versions too.

kvm -vnc :0 -usbdevice tablet -usbdevice host:064f:0bd7 -usbdevice host:0529:0001 -k de -net nic,vlan=0,macaddr=00:50:56:00:08:15 -net tap,vlan=0,ifname=tap21,script=no -m

Okay, please try again with the newest kvm, the problem may have been fixed already.
