Description CongLi 2013-09-27 12:53:45 UTC

Description of problem:
Can't boot a guest with snapshot=on

Version-Release number of selected component (if applicable):
kernel-3.10.0-23.el7.x86_64
qemu-kvm-1.5.3-7.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Boot a Win2003 guest w/ snapshot=on
/usr/libexec/qemu-kvm \
-drive file='/root/staf-kvm-devel/autotest-devel/client/tests/virt/shared/data/images/win2003-32-virtio.qcow2',index=0,if=none,id=drive-virtio-disk1,media=disk,snapshot=on,cache=unsafe,format=qcow2,aio=native \
-device virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk1,bootindex=0 \

2.
3.

Actual results:
Guest can't boot up w/ error:
qemu-kvm: -drive file=/root/staf-kvm-devel/autotest-devel/client/tests/virt/shared/data/images/win2003-32-virtio.qcow2,index=0,if=none,id=drive-virtio-disk1,media=disk,snapshot=on,cache=unsafe,format=qcow2,aio=native: Can't use snapshot=on with driver-specific options

Expected results:
Guest boot up successfully

Additional info:
1. qemu-kvm-1.5.3-3.el7.x86_64 works for me
