SymptomsAfter change of MAC address on the Network Adapter of the Hardware Node, some VEs are not accessible over network.
CauseThe VEs, which have Bridged Network type are mapped to a Network ID which is assigned to physical network adapter. These settings are configured in the Virtuozzo Network Configurator. If MAC address of physical network adapter is changed, the Network ID is lost.
ResolutionGo to Network Configurator, assign a new Network ID to the Network Adapter, then change the Network ID of the VE to the newly created Network ID.
After that it is necessary to restart the VE.
