[Qemu-devel] Spontaneous reboots with FreeBSD + amd64 + kqemu

[Qemu-devel] Spontaneous reboots with FreeBSD + amd64 + kqemu

[David Thiel]

Hello,

I've just moved from an x86 machine to a Core 2 Duo machine, a Thinkpad
X60 tablet, running FreeBSD 6.2-STABLE. I've enabled NET_WITH_GIANT
and made sure that the kqemu module matches my kernel, which has SMP
enabled. When trying to start qemu 0.9.0 with my old WinXP SP2 VMs, I
get a Windows loader screen for a short while, and then my host hangs
and reboots, giving no error messages. This happens in regular and full
virtualization modes.

Is there anything I can do to get some debugging information from kqemu?
Are there known problems running a 32-bit WinXP with kqemu on a 64-bit
FreeBSD or Linux host?

Thanks,
David

Hmm, have u tried a up kernel to see if the problem is smp related?

 Actually there's debug.kqemu_debug sysctl you could enable, that logs
some of the kqemu calls to dmesg (you probably could add more
`if (kqemu_debug > 0) kqemu_log(...)' to kqemu-freebsd.c if you want.)

 Others will have to answer that one...
