*** Bug 858775 has been marked as a duplicate of this bug. *** Reproduced on qemu-kvm-0.12.1.2-2.295.el6_3.2.
Steps
1. boot guest
#/usr/libexec/qemu-kvm -m 8G -smp 8,cores=8,sockets=1,threads=1 -cpu SandyBridge -drive file=/root/RHEL-Server-6.4-64-virtio.qcow2,format=qcow2,if=none,id=drive-virtio-disk0,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,drive=drive-virtio-disk0,id=virtio-blk-pci0,bootindex=1 -netdev tap,sndbuf=0,id=hostnet0,script=/etc/qemu-ifup,downscript=no,vhost=on -device virtio-net-pci,netdev=hostnet0,mac=00:10:1a:61:72:01,bus=pci.0,addr=0x4,id=virtio-net-pci0 -uuid 7678e130-f1a7-4157-875a-8defcdb27af7 -rtc base=localtime,clock=host,driftfix=slew -vnc :1 -M rhel6.3.0 -monitor stdio -qmp tcp:0:4444,server,nowait
2. Do live snap shot
{ "execute": "transaction", "arguments": {'actions': [ { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'drive-virtio-disk0', 'snapshot-file': '/root/blockcopy/sn1' } }] } }
3. do mirror
{ "execute" : "__com.redhat_drive-mirror", "arguments" : { "device" : "drive-virtio-disk0", "target" : "/root/blockcopy/sn2", "format": "qcow2", "mode": "absolute-paths"} }
4. shut down guest
Results:
sn2(mirroring target) > sn1(mirroring source)
#ls -sh
16M sn1 81M sn2
Verify on qemu-kvm-rhev-0.12.1.2-2.295.el6_3.4.x86_64.
Steps
1. boot guest
#/usr/libexec/qemu-kvm -m 8G -smp 8,cores=8,sockets=1,threads=1 -cpu SandyBridge -drive file=/root/RHEL-Server-6.4-64-virtio.qcow2,format=qcow2,if=none,id=drive-virtio-disk0,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,drive=drive-virtio-disk0,id=virtio-blk-pci0,bootindex=1 -netdev tap,sndbuf=0,id=hostnet0,script=/etc/qemu-ifup,downscript=no,vhost=on -device virtio-net-pci,netdev=hostnet0,mac=00:10:1a:61:72:01,bus=pci.0,addr=0x4,id=virtio-net-pci0 -uuid 7678e130-f1a7-4157-875a-8defcdb27af7 -rtc base=localtime,clock=host,driftfix=slew -vnc :1 -M rhel6.3.0 -monitor stdio -qmp tcp:0:4444,server,nowait
2. Do live snap shot
{ "execute": "transaction", "arguments": {'actions': [ { 'type': 'blockdev-snapshot-sync', 'data' : { 'device': 'drive-virtio-disk0', 'snapshot-file': '/root/blockcopy/sn3' } }] } }
3. do mirror
{ "execute" : "__com.redhat_drive-mirror", "arguments" : { "device" : "drive-virtio-disk0", "target" : "/root/blockcopy/sn4", "format": "qcow2", "mode": "absolute-paths"} }
4. shut down guest
Results:
sn2(mirroring target) = sn1(mirroring source)
#ls -sh
9.9M sn3 9.9M sn4
