I suspect you have a QEMU/KVM config issue of some sort given that doesn't happen to anyone else that I've seen. It's not an issue in our code regardless.

I have the same pb. FreeBSD guests fail to reboot properly if they have more than one CPU (socket, core, and/or thread).
It seems to be hardware specific : https://bugs.launchpad.net/qemu/+bug/1329956

As determined on the mailing list in June, the bug appears to be with KVM's apicv on processors that support the feature. I haven't heard anything about a fix, but the best workaround is to disable apicv when loading the KVM kernel module, e.g.:

# modprobe kvm_intel enable_apicv=N

You can verify the parameter by checking the contents of /sys/module/kvm_intel/parameters/enable_apicv.
