[libvirt-users] Migration failure after libvirt upgradation

Team, I'm trying to migrate a domain offline(shutdown mode) using libvirt-python API 'migrateToURI' but it gives me an error : libvirt: QEMU Driver error : Requested operation is not valid: domain is not running When I tried the same API for live migration(running and suspend mode), it gives me an error: libvirt: QEMU Driver error : Unsafe migration: Migration may lead to data corruption if disks use cache != none Below are the versions of the virtualization softwares I am using currently : Hypervisor : KVM qemu : 1.0 qemu-kvm : 1.0 Libvirt : 1.2.1 Earlier, I had performed offline and live migration *successfully* with these versions: Hypervisor : KVM qemu : 1.0 qemu-kvm : 1.0 libvirt : 0.9.8 Also, I would like to know whether it's possible to migrate a domain having snapshots? Kindly guide me through this. Thanks in advance Regards, Shweta
