Steps to Reproduce:
1.
/home/autotest-devel/client/tests/kvm/qemu -name vm1 -nodefaults -chardev socket,id=human_monitor_id_humanmonitor1,path=/tmp/monitor-humanmonitor1-20120713-162245-j9qs,server,nowait -mon chardev=human_monitor_id_humanmonitor1,mode=readline -chardev socket,id=serial_id_20120713-162245-j9qs,path=/tmp/serial-20120713-162245-j9qs,server,nowait -device isa-serial,chardev=serial_id_20120713-162245-j9qs -device ich9-usb-uhci1,id=usb1,bus=pci.0,addr=0x4 -drive file=/home/autotest-devel/client/tests/kvm/images/RHEL-Server-7.0-64-virtio.qcow2,index=0,if=none,id=drive-virtio-disk1,media=disk,cache=none,boot=off,snapshot=off,format=qcow2,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk1,id=virtio-disk1 -device virtio-net-pci,netdev=idTS4cxm,mac=9a:79:ba:f9:21:9e,id=ndev00idTS4cxm,bus=pci.0,addr=0x3 -netdev tap,id=idTS4cxm,fd=21 -m 16384 -smp 4,cores=2,threads=1,sockets=2 -cpu Penryn -device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1 -vnc :0 -vga cirrus -rtc base=utc,clock=host,driftfix=slew -M pc-1.0 -boot order=cdn,once=c,menu=off -no-kvm-pit-reinjection -enable-kvm
2.run some simple test, 
 guest <-scp -> host
3.shutdown guest
  
Actual results:
2012-07-13 18:45:08: [  113.167239] shutdown used greatest stack depth: 2728 bytes left
2012-07-13 18:45:08: [  113.174392] Kernel panic - not syncing: Attempted to kill init!

Expected results:

guest should shutdown w/o error

1) tried shutdown on the host, works fine

2) reboot guest, works fine (tried 30 rounds.)

this should already be fixed with latest dracut in F17
