Description of problem:
Start Windows and Fedora VMs.
Drain the node that the VMI are running on.
Fedora VMI is migrated successfully; Windows VMI fails to migrate.

Version-Release number of selected component (if applicable):
CNV 2.6.0 (virt-operator-container-v2.6.0-95)

How reproducible:
100%

Steps to Reproduce:
1. Create Windows DV
2. Create Windows VM from template
oc process -n openshift windows2k19-server-medium-v0.12.3 -p NAME=win-19 -p PVCNAME=win-19

3. Start VM
4. Drain the node that hosts the VMI
oc adm drain <node name> --delete-local-data --ignore-daemonsets=true --force

Actual results:
VMI migration fails on:
server error. command Migrate failed: "LibvirtError(Code=27, Domain=20, Message='XML error: non unique alias detected: ua-')"

Expected results:
VMI migration should succeed.

Additional info:

• Fedora VMI (BlockMigration/LiveMigration) succeeds.
• Attached:

• Windows:
  • DV and VM yamls
  • VM/VMI yamls
  • dumpxml
  • source and target pods
  • VMI describe
• Fedora (BlockMigration/LiveMigration) VMs and VMIs yamls and domxml
