Migration failure after libvirt upgradation

[Shweta Salaria <salaria.shweta@xxxxxxxxx>]

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
