A VNC console doesn't open for a Virtual Machine in PVA or Power Panel with the following error displayed:
Network error: connection has been shutdown javax.net.ssl.SSLHandshakeException : Remote host closed
Power Panel doesn't work for any Virtual Environment on the server.
There has been a change of IP address(es) on the hardware node recently with
service network restart, and no server reboot happened ever since.
The old node's IP appears in the proxy log of CT 1
T=2014.05.20 04:19:31.513249; L=[info]; PID=1; connection created from 9 to 10 T=2014.05.20 04:19:31.513277; L=[info]; PID=1; connect to remote host 192.168.1.2, port 4649 done, fdin - 9, fdout - 10 T=2014.05.20 04:20:34.512684; L=[info]; PID=1; connection created from 10 to 9 T=2014.05.20 04:20:34.512766; L=[info]; PID=1; disable connection on read from 10, result - -1, strerror - Connection timed out T=2014.05.20 04:20:34.512793; L=[info]; PID=1; connection shutdown from 9 to 10, strerror - Connection timed out T=2014.05.20 04:20:44.523203; L=[info]; PID=1; connection closed from 10 to 9
In this example, 192.168.1.2 is an old IP and no longer exists on the hardware node.
CT 1 dumps the hardware node's IPs on its start and uses them later for proxying connections on offline management services, which are used for VNC console in PVA and for Power Panel.
Restart container 1:
# vzctl restart 1
