------------------------------------------

             Summary: SSh to few vms are failing
                 Key: CLOUDSTACK-8790
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8790
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.6.0
            Reporter: shweta agarwal
            Priority: Critical


Repro steps:
create a ssh keypair
Deploy several VMs with keypair field
destroy  few vms 
deploy more vms with keypair

Bug:
Notice keypair for certain VMs are not set hence ssh for those vms are failing

MS log for those vms shows :
