automatic reboot winxp hanging on vnc...

[Thomas Besser]

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?

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.

Yepp. Guest ist started like with:

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
256 -localtime -daemonize ./lizenzknecht.raw

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