Description

Executed scenario:
Setup: 2 KVM clusters:

• Cluster1 - KVM-Host2 (1 host)
  • KVM-Host2 - 0 instances

• Cluster2 - KVM-Host3, KVM-Host4 (2 hosts)
  • KVM-Host3 - 3 instances
  • KVM-Host4 - 1 instance

all instances have service offer - Offer HA - Yes

Steps to reproduce:

1. Set enable.ha.storage.migration=true in Global Settings
2. Restart management server.
3. Shut down kvm4

Result:
Running instances are not migrated to suitable host in other cluster (cross-cluster migration)

• KVM4 still having one instance, but host is in disconnected state
• KVM2 should have received the instance but still has 0 instances.
• KVM3 unchanged
