Rohit Yadav closed CLOUDSTACK-8530. ----------------------------------- Resolution: Fixed Fixed on master/4.5 branches > 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. > To reproduce the issue: > 1. On a KVM host, drop packets from mgmt server host IP: iptables -A INPUT -s > 192.168.1.12 -j DROP (here 192.168.1.12 is the mgmt server IP) > 2. After Investigator kicks in neighbours report that it's Up, now deploy a > VM on this host it fails. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
