Hi,

We have been trying to get live migration working between two xen boxes running libvirt 1.2.12, However i seem to be getting the following error

root@libvirt-xen1:~# virsh migrate --live trusty-image qemu+ssh://192.168.13.9/system --copy-storage-all --verbose --persistent --undefinesource root@192.168.13.9's password: error: unsupported flags (0x48) in function libxlDomainMigrateBegin3Params

root@libvirt-xen1:~# virsh migrate --live trusty-image xen+ssh://192.168.13.9/system --copy-storage-all --verbose --persistent --undefinesource root@192.168.13.9's password: error: unsupported flags (0x48) in function libxlDomainMigrateBegin3Params

Any ideas as to why this might be happening ?

I believe that's because libvirt's xen driver does not know how to handle --copy-storage-all. Michal
