[libvirt-users] error when call migrate function "error: invalid argument: qemuDomainMigratePrepare3: unsupported flags (0x200)"

[loic.cloatre at orange.com]

Hello,

I try to migrate a VM and I get this error :
loic at loic-VirtualBox:~/workspace/src/build/bin$ ./virsh --connect qemu:///system migrate  --live vmUbuntuPartage2CacheWriteBack qemu+ssh://192.168.10x.2x/system --unsafe
loic at 192.168.10x.2x's password:
error: invalid argument: qemuDomainMigratePrepare3: unsupported flags (0x200)

Does somebody know this error?

I am working on windows 7, I have:

1)      Virtual box with two vms ubuntu desktop 12.04: "VM1" and "VM40"

2)      One shared hard drive build with virtual box: "newDiskSharedFev.vdi"

In my VM1:

1)      I have build one "vmUbuntuPartage" ubuntu server 12.10 on shared disk with this command:
sudo virt-install -n vmUbuntuPartage -r 1500 --disk path=/media/partage/newDiskSharedFev.vdi,bus=virtio,size=4,cache=writeback -c /home/loic/Downloads/ubuntu-12.04.1-server-i386.iso --network network=default,model=virtio --connect=qemu:///system --vnc -v

2)      I have download and built libvirt-0.10.0 (I can give configure command if necessary)

In my VM40:

1)      I install libvirt with apt-get

2)      I have mounted shared folder with "newDiskSharedFev.vdi"

So, in my VM1 I try to migrate my "vmUbuntuPartage" from VM1 to VM40 and I get error above.

Here my configuration file /etc/libvirt/qemu/ vmUbuntuPartage.xml
-->
I try to change <driver name='qemu' type='raw'  cache='none or writeback or writetrough'/>
