Networking not starting with Debian lenny

[dafydd]

Hi,

I've been experimenting with Proxmox and it's looking great so far. But I've hit a snag with networking.

I installed Proxmox 1.5 from a CD, and created two guests from the downloaded Open VZ templates - one with Debian etch and one with lenny.

Of course I updated both installations to the latest packages etc and all was working fine. I had to reboot the host machine and after that the etch VM came back up ok, but not the lenny install.

In the guest.. trying to bring the interfaces up manually I get:

ifconfig lo up
ifconfig venet0 up
ifconfig venet0:0 up
SIOCSIFFLAGS: Cannot assign requested address
​

I've seen discussions here about issues with Ubuntu 9.10 but I'm not sure if that applies here.

So.. how can I get the guest networking back up and running?

Thanks.

Well, after 2 hours I've fixed it. Initially I thought maybe I'd installed a package that is not needed in VMs and was clashing with some networking or device initialisation. But it turned out that reinstalling the ifupdown package fixed it. It was there previously too so I'm not quite sure what it fixed.
