[kvm-devel] bugreport: guest crashes on reboot in KVM 65 on AMD

[Michal L. <ml...@lo...>]

Hi all,

in short: CentOS 5 guest (32bit) crashes when I run "reboot" in the VM 
with qemu message:
kvm_run: failed entry, reason 65535
kvm_run returned -8

In dmesg is this message:
kvm: 23769: cpu0 kvm_set_msr_common: MSR_IA32_MC0_STATUS 0x0, nop

Details:
KVM 65
Host is openSUSE 10.3 with my own 2.6.24, 64 bit
Guest is CentOS 5.1 with 2.6.18-53.1.14.el5, 32 bit
GCC 4.2.1 for module, GCC 3.3.3 for qemu
CPU "AMD Athlon(tm) 64 X2 Dual Core Processor 5600+"

Everything works fine, except that I can't reboot the guest. In VNC it 
says "md: stopping devices" and then Qemu exits with:
kvm_run: failed entry, reason 65535
kvm_run returned -8

IIRC reboot used to work with kvm-64

If you need more information let me know.
