I am running 2.6.23.1 with kvm built from that tree as a module. My system is running Debian/testing on a Tyan board with two dual-core Opteron 2216 processors; each socket has 4G of RAM. I have attached the serial console dump including a bunch of output from SysRq (gzipped, because it was 300k otherwise).
I have ran multiple passes of memtest, and I can build the kernel with
-j8, but when I run kvm the host freezes.
A bit about the system:
quark# cat /proc/version
Linux version 2.6.23.1 ([EMAIL PROTECTED]) (gcc version 4.2.1 (Debian 4.2.1-4))
#5 SMP Fri Oct 19 14:10:30 EDT 2007
quark# kvm --help
QEMU PC emulator version 0.9.0, Copyright (c) 2003-2007 Fabrice Bellard
My kvm is started as follows; the guest is a 64bit version of RHEL5
(redhatized 2.6.18 kernel).
kvm -m 512 -vnc quark:12 -k en-us -usbdevice tablet -serial vc -k en-us -boot c
-hda rhel5.img -net nic,vlan=0 -net user,vlan=0 -redir tcp:2222::22 -redir
tcp:8080::8080 -redir udp:8080::8080
I added --no-acpi with no improvement.
I also tried running with taskset -c 0 with no improvement.
Once the system is booted, I attached using vnc, then I ssh in and ran
'svn update'... and the host machine froze.
The last messages I on my serial console are:
kvm: unhandled rdmsr: 0x417
kvm: unhandled rdmsr: 0xc0000400
kvm: unhandled rdmsr: 0xc0000401
kvm: unhandled rdmsr: 0xc0000402
kvm: unhandled rdmsr: 0xc0000403
kvm: unhandled rdmsr: 0xc0000404
kvm: unhandled rdmsr: 0xc0000405
kvm: unhandled rdmsr: 0xc0000406
kvm: unhandled rdmsr: 0xc0000407
And then freeze.
As this is pretty easy to reproduce, I am quite happy to run any patches
or configurations that people come up with :)
I noticed that linus merged a bunch of KVM changes last week. I will
try those out next.
Thanks in advance for looking at this.
