Hi Matthew,
I actually managed to fix it an hour after posting by specifying '-cpu host'
to kvm,
I tried this after reading
http://lists.freebsd.org/pipermail/freebsd-amd64/2014-January/015790.html
and discovering the message "KVM: Guest triggered AMD Erratum 383" in dmesg
So it seems there is some bug with amd64 host and the qemu virtual CPU
cheers,
Andrew

Hi Andrew.
What is your hypervisor's hardware spec, meaning is there AMD cpu, perhaps
Ipteron? Because in my case, after switching HW (to intel based), the issue
seems is gone. The guest is working stable now.
Regards,
Matthew
the truth is negotiable

Hi Matthew
Hello,
I'm experiencing strange behaviour with any FreeBSD 64bit running under KVM
Qemu. When machine is under high load for example compiling from ports,
after a random time it will get rebooted with no piece of information in
logs or what so ever. In this case I'm unable to get any kernel
panic/traces (kdb is enabled). On the KVM side also there are no error
logs.
This is confirmed on FreeBSD amd64 8.4; 9.0; 9.1; 9.2-RC and 10-Current.
Anyone experienced such behaviour on 64bits or mayby have a clue how can I
debug this?
This exactly is happening to me now.
My host is a Debian Wheezy AMD64 running Qemu kvm 2.0.0+dfsg-4~bpo70+1
My guest is FreeBSD 10 FreeBSD 10.0-RELEASE (GENERIC) #0 r260789error about
And part way through make world via freebsd-wifi-build/build/bin/build I am
experiencing spontaneous reboots.
My kvm command line is:
kvm --enable-kvm -localtime -m 1536 -smp 2 -k en-us -hda freebsd.qcow2 \
-soundhw sb16 -net nic -net user,hostfwd=tcp::62222-:22 -monitor stdio
I built this VM and a build of world kernel install etc. completed without
problems yesterday.
But today when I repeated after a clean I am experiencing the problem.
I am wondering whether having accidentally killed the guest corrupted to disk
somehow, but the problem keeps happening even after running fsck on /
With kind regards,
Matthew
HTH,
Andrew
