CloudStack makes use of this SXM feature and supports the following use cases: #

support Live Migration of a VM along with volumes
- within a resource pool
  - VM on local storage
  - VM on shared storage pool where SR is NOT shared between the hosts
  - VM on shared storage pool where SR is shared between the hosts (This is already supported)
- across resource pool
  - VM on local storage
  - VM on shared storage pool
support volume migration between SRs while the VM is on the same host(with in same resource pool)

Scope:

The scope of this test plan includes the following:

This is valid for XenServer 6.1 deployments
covers Local and shared storage-NFS,iSCSI related testing
Upgrade testing
Fresh installations with ACS 4.2
test the support of for Live Migration of a VM along with volumes
- within a resource pool and
- across resource pool
- pool
  - VM on local storage
  - VM on shared storage pool where SR is NOT shared between the hosts
  - VM on shared storage pool where SR is shared between the hosts (This is already supported)
- across resource pool
  - VM on local storage
  - VM on shared storage pool
test support for volume migration between SRs while the VM is on the same host(with in same resource pool)
test new APIs
- listHostsForMigration
- migrateVirtualMachineWithVolume
- listStoragePoolsForMigration
- migrateVolume
test DB changes
- newly added field "storage_migration_supported" in the tabe "hypervisor_capabilities"
negative scenarios
- failure cases
  - when SXM fails
  - VM operations while SXM is happening
UI work flow
- volume migrate option while Volume is attached to a running VM
- live migrate VM
