Description Qian Guo 2015-02-11 06:12:59 UTC 
Description of problem:
Do s3 and resume inside a rhel7.1 guest that under q35 machine type, then try to shutdown it, but it prompt:

dracut Warning: poweroff failed

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.1.2-23.el7.x86_64

guest/host kernel-3.10.0-229.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Boot a rhel7.1 guest under q35 machine type
# /usr/libexec/qemu-kvm -name rhel7 -S -machine pc-q35-rhel7.1.0,accel=kvm,usb=off -m 4096 -cpu SandyBridge -realtime mlock=on -sandbox on -smp 4,maxcpus=4,sockets=4,cores=1,threads=1 -no-user-config -nodefaults -boot menu=on -drive file=/home/rhel7.1q35/rhel7.1q35.qcow2,if=none,id=drive-blk-disk,format=qcow2,cache=writethrough,werror=stop,rerror=stop -device virtio-blk-pci,scsi=off,bus=pcie.0,addr=0x2,drive=drive-blk-disk,id=virtio-disk0  -device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vgamem_mb=16,bus=pcie.0,addr=0x3 -device ich9-intel-hda,id=sound0,bus=pcie.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0  -device virtio-balloon-pci,id=balloon0,bus=pcie.0,addr=0x6 -monitor stdio -qmp tcp:0:4444,server,nowait -serial unix:/tmp/s1,server,nowait -spice port=5900,disable-ticketing  -netdev tap,id=hostnet0,vhost=on,id=hostnet0,fds=5:15:25:35 5<>/dev/tap5 15<>/dev/tap5 25<>/dev/tap5 35<>/dev/tap5 -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=0e:49:5d:6e:f9:f5,mq=on,vectors=10,bus=pcie.0,addr=0x7 -global ICH9-LPC.disable_s3=0 -global ICH9-LPC.disable_s4=0

2.In side guest, do s3 and resume

3.shutdown guset
guest# shutdown -h now

Actual results:
Can not shutdown guest finally, it prompt

"dracut Warning: poweroff failed"

and qemu-kvm can not quit

Expected results:
Can shutdown guest successfully

Additional info:
1.-machine pc won't hit such issue.

2.if do not do s3, can not hit such issue
