[Devel] Re: [Lxc-users] PHYS type lxc not working

[Sabdar]

Hi,
     i tried the same but by upgrading to the latest ip utility and its
works fine as you specified.With the old ip utility the "link add" commands
fails,Thanks for the help.

I tried "PHYS" in the kernel version 2.6.35-rc4 and phys seems to work but
with a problem ie) the working configuration is as follows,

lxc.utsname = gamma
lxc.network.type = phys
lxc.network.flags = up
*lxc.network.link = eth0*
*lxc.network.name* <http://lxc.network.name/>* = eth0*
lxc.network.ipv4 = 192.168.10.1

The same when we change as below  fails to release the host interface after
lxc is stopped

lxc.utsname = gamma
lxc.network.type = phys
lxc.network.flags = up
*lxc.network.link = eth1*
*lxc.network.name* <http://lxc.network.name/>* = eth0*
lxc.network.ipv4 = 192.168.10.1

Instead i see an interface as dev3 in my host after the lxc is stopped.Is it
necessary that both the network.link and network.name has to be same in the
case of "PHYS".

Thanks,
Sabdar.
