KVM-17 & WinXP network setup hangs

KVM-17 & WinXP network setup hangs

[Alessandro Sardo]

Hello KVM devs,

I've just downloaded and checked out KVM-17. I tried 
installing a Windows XP SP2 guest, using the following 
script (notice how I did NOT use the '-no-acpi' flag):

qemu -hda /var/vm/img/WinXP.img -cdrom 
/var/vm/iso/WinXP.iso -boot d -m 512

The first phase of installation went straight without any 
problem - and it was quite faster than previous releases! 
Then, when the guest had to reboot, KVM crashed with the 
following output:

unhandled vm exit:  0x80000021

Not a big problem though, I just manually restarted it and 
kept going on with the second phase of the installation.

This is where I got the big problem: after installing the 
devices and asking for the cd-key (among other things), 
the guest totally *stalled* while configuring the network. 
It just says "Installing the network...", but the progress 
bar is frozen - and there's no output on the shell. I've 
also tried with the '-net nic,model=rtl8139' flag, but the 
result was the same. I'm unable to complete the 
installation.

Is there a work-around for this?

Thanks!

That's a known issue, we don't handle reboot on Intel.

It may be related to unsynced timestamp counters.  Can you try prefixing 
your command with 'taskset 1'?  Like so:

   taskset 1 qemu -hda ...


-- 
error compiling committee.c: too many arguments to function

Hi,
Do you use a software bridge and a tun/tap device ?
If you do, what is your network configuration (host + guest) ?
If you do not, search the list to find how to do it.
You'll need to setup a bridge (either manually or using an init script posted), and add a '-net tap,script=/etc/kvm/qemu-ifup' to qemu command line. 
 
Hope that helps,
    Uri.
