---------------------------------------
Summary: KVM hosts without active agent connection are still "Up"
Key: CLOUDSTACK-8530
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8530
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: KVM
Reporter: Rohit Yadav
Assignee: Rohit Yadav
Fix For: 4.6.0, 4.5.2
KVM hosts without active agent connection are still "Up". In case a KVM host
get uncleanly disconnected from the mgmt server, for example due to a firewall
rule or physical nic unplugging the neighbour KVM hosts might investigate and
report that the KVM host is in Up state but since mgmt server is not connected
to the agent (on that host), all further commands such as VM migrations, VM
deployments etc fail.
The best fix would be to have the investigator check the KVM host itself and if
it's unable to contact return the state as disconnected, this way no HA for VMs
will be triggered.
