kvm.git+ qemu.git:fd275235_8b303011
kernel version:3.17.0-rc1
test on Ivytown_EP
qemu-system-x86_64 -enable-kvm -m 4G -smp 2 -net nic,macaddr=00:13:13:51:51:15
-net tap,script=/etc/kvm/qemu-ifup nested-xen.qcow -cpu kvm64
the L1 guest panic and reboot, the bug can reproduce.

when I try enable_apicv=1 or enalbe_apicv=0
create guest
qemu-system-x86_64 -enable-kvm -m 4G -smp 2 -net nic,macaddr=00:13:13:51:51:15
-net tap,script=/etc/kvm/qemu-ifup nested-xen.qcow -cpu kvm64
or 
qemu-system-x86_64 -enable-kvm -m 4G -smp 2 -net nic,macaddr=00:13:13:51:51:15
-net tap,script=/etc/kvm/qemu-ifup nested-xen.qcow -cpu host
the bug can reproduce.
