There is a mandatory prerequisite for this procedure: bridged interface(s) should be configured on the hardware node in order to make the conversion work.


Configure the Front Net and the Back Net virtual networks on the hardware node in bridged mode. Please refer to the Virtuozzo User Guide for details:

For example, if you need to create bridged network named Backnet associated with the adapter eth0, the following actions should be done:

# vznetcfg net new Backnet
# vznetcfg net addif backnet eth0
