Virtual network may lose binding to a VLAN infterface, if
service network restart was invoked on the hardware node. As the result, virtual environments in bridged mode may lose network connections.
~# vznetcfg net list | grep vlan vlannetwork active eth0.3 ~# service network restart ~# vznetcfg net list | grep vlan vlannetwork active
The issue has been registered as a product defect PSBM-20547.
The bug is fixed in Virtuozzo 6.0 Update 11 (6.0.11-3429).
Install pending updates to prevent issue from reoccurring.
To fix already broken network configuration, restart 'vznetcfg':
~# service vznetcfg stop; sleep 3; service vznetcfg start
(On some installations,
service vznetcfg restart does not help to fix the issue, a delay is needed for proper reconfiguration.)
If possible, perform
ifdown IFACE; ifup IFACE to apply changes to the specific interface.
To avoid the issue on pre-Update 11 installations, stop
vznetcfg before restarting
network and start it after:
~# service vznetcfg stop; service network restart; service vznetcfg start
