SymptomsThe target w2k8 container is not reachable over the network after p2v migration. Firewall inside the container is switched on even if it was disabled on the source physical server.
ResolutionSwitch Windows firewall off inside the container by running this command on the node:
vzctl exec CT_ID netsh advf set all state off
where CT_ID is numeric identifier of the conatiner.
Then login to the conatiner and configure Windows firewall rules by using GUI and turn it on.
