Title:
Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1
Status in QEMU:
New
Bug description:
After Upgrading to qemu-kvm-1.1.1-r1 from version 1.0.1-r1 my virtual
machines (running gentoo linux) panic at intel_pmu_init. (detailed
information including stacktrace are in the uploaded screenshot). When
i remove the "-cpu host" option, the system starts normally.
the command line from whicht the system is bootet:
qemu-kvm -vnc :7 -usbdevice tablet -daemonize -m 256 -drive
file=/data/virtual_machines/wgs-l08.img,if=virtio -boot c -k de -net
nic,model=virtio,macaddr=12:12:00:12:34:63,vlan=0 -net
tap,ifname=qtap6,script=no,downscript=no,vlan=0 -smp 2 -enable-kvm
-cpu host -monitor unix:/var/run/qemu-
kvm/wgs-l08.monitor,server,nowait
also reported on gentoo bug tracker (with some more details of the
host): https://bugs.gentoo.org/show_bug.cgi?id=431640
