I have been testing KVM for eventual use in a production server environment and am running into some trouble when I attempt to rsync my data from the current production system to the test system. Specifically, whenever I hit a large file, the guest freezes and I get the following in the host's system log:

Nov  8 16:14:20 vcr1 kernel: [2847590.399951] kvm: 10680: cpu0 unhandled 
wrmsr: 0xc1
Nov  8 16:14:20 vcr1 kernel: [2847590.399959] inject_general_protection:

rip 0xc01162ff

I have Googled the error, but can't see anything that leads me to believe that I've made any errors in the configuration. Other things seem to work fine, but I can reproduce this freeze every time. Here's a recap of my environment...

CPU Model: Intel Xeon 5130 2.0 Ghz
KVM Version: 50
Host Kernel: Linux version 2.6.20-16-generic (root@king) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #2 SMP Sun Sep 23 18:31:23 UTC 2007 Host Kernel Arch: i386
Guest: Ubuntu Gutsy (i386)
QEMU Command Line: /opt/kvm/bin/qemu-system-x86_64 -hda /home/kvm/images.d/w5.img -boot c -m 384 -net nic,macaddr=00:14:1C:30:AF:03 -net tap,ifname=tap3,script=no -daemonize -vnc :3

Thanks for any pointers you can provide.

The error probably appears even before the freeze (right after boot).

Thanks for any pointers you can provide.

Please try '-net nic,model=rtl8139,...'

Though a long bug report on sourceforge doesn't indicate much chances of success.
