[Libvirt-cim] [PATCH 4 of 4] [TEST][RFC] #2 Added new tc to verify remote live migration

# HG changeset patch # User Deepti B. Kalakeri <deeptik(a)linux.vnet.ibm.com&gt; # Date 1237188257 25200 # Node ID 8a282c8879a9986c2bdde0238a4307ea3378ee4b # Parent c272bb5f4c9fcbceb6e70d0b5a0cd0ea40359e72 [TEST][RFC] #2 Added new tc to verify remote live migration. Updates: -------- Patch 2: ------- 1) Moved the VSMS object creation to vsmigration.py local_remote_migrate() fn. 2) Added check for domains on src and target, Undefined & destoryed domain on src and target depending on their existence. Verified with KVM. The test case will not pass for KVM since the guest information needs to have emulator information without which the remote migration fails. The support to pass the emulator information via VirtualSystemMigrationSettingData is not yet available. Signed-off-by: Deepti B.
