No, it shouldn't.  We used it with the 2.6.18, .24, and .32 kernels.
(Also, the basic technique works fine all over the place with Linux
alone. :)

I would suggest you work through and identify which component is not
working: check the NIC shows inside the container, and is configured
correctly.  Send some traffic over it and check that it reaches the
pair device in the "hardware" node, and then the bridge.

Once you identify where along the chain it is failing it should be a
lot easier to solve the specific issue.

You know how a software bridge works, right?  It copies packets from
one NIC to another at the Ethernet level.  So, if you want the
container attached to the same network as eth0 on the host, the bridge
needs to live on that.

As for the rest of the bridge configuration: technically, all you need
is that the hardware device and bridge are up.  Assigning an IP
address would be typical - and it would effectively take over the role
that eth0 had played before hand.  It isn't technically required,
however.

(You should use the PVE interface to configure this, though, because
it does the right thing for you.)
