[kvm-devel] Starting a VM reboots my machine

Hi,

I'm running an AMD

vendor_id       : AuthenticAMD
cpu family      : 15
model           : 75
model name      : AMD Athlon(tm) 64 X2 Dual Core Processor 4600+

with 4GB of RAM and Scientific Linux 5.0. I've compiled kvm-48 on it and
the compile works and loading the modules works fine, the only dmesg
line referring to kvm is SELinux: initialized (dev kvm_anon_inodefs,
type kvm_anon_inodefs), not configured for labeling.

However, when I boot any KVM, the machine reboots.  It works fine with
the no-kvm flag.  Has anyone else seen this behaviour?

We have some instabilities with AMD. These issues are under debug these days.
Can you please supply netconsole debug messages from the host. This can be very helpful.
Also what's the guest OS?

These is a slight chance that kvm-49 and -no-kvm-irqchip will help.
Dor.

Thanks,
Cam
