Sun Virtualbox + Ubuntu/Debian
I ran into some peculiar problems with Ubuntu Server 8.10 running under Virtualbox. First after installing Ubuntu Server 8.10 (Intrepid) the kernel failed to boot. It turns out that this was due to the fact that PAE/NX (Physical Address Extensions on the Host) are not enabled by default in the VM. To enable this you need edit the settings of your VM: Settings > General > Advanced > Extended features > PAE/NX.
Secondly, even after installation and boot woes are sorted out – networking for whatever reason is busted. It took me forever to figure out why – first I installed Debian, then Ubuntu to no avail – APT would fail to resolve the mirrors even though I could ping (ICMP) the servers. I thought it could have been due to the firewall rules on the host machine, but these wheren’t the problem! It turned out that the fix was to change the network adapter from PCNET-FASTIII to Intel PRO/1000 T Server. After that, I had no trouble with DNS resolution and traffic issues. I’m lazy so I haven’t bothered to check what the underlying problem might have been – but hopefully this helps someone else out there!

I have had similar random strange problems when upgrading to Ubuntu 8.10. Most of which have been related to hardware.
e.g. Sysctl table errors with the printer port, sound card problem (on board card not found), Video resolution modes not detected (Nvidia), Mysql memory problems, Gallery 2 database corrupted (required reinstall)…
Very frustrating, but I think I have fixed most of the problems now in a similar way to your Network card fix… Replaced or substituted hardware which was causing problems.

Its bizarre that there should be so many problems, especially with a commercially backed OS. I guess its difficult to test for every permutation of hardware out there…
