Open Source Virtualization in Ubuntu Hardy (First Impressions)
So Open Source Virtualiztion in Ubuntu hasn't been a smooth ride. The linux-virtual and linux-xen kernels panic my T-61 due to what appear to be SATA and USB issues, respectively, but KVM seems to be working a little better (you need to apt virt-manager, kvm, libvirt-bin, and probably a few others) and actually surprisingly snappy.
Virtual Manager is now included and works reasonably well (if run as root, there are some permission issues) to provide VMWare-console like experience. I was able to boot (from the .iso) a Debian Etch install but I aborted due to hda (DSC Timeouts) but Hardy Server worked amazing well:
root@ubuntu:~# uname -a

Networking "just worked" a pleasant suprise thinking about what a pain it used to be back in the day with User Mode Linux. You'll also note that you connect into the console via VNC, which was nice.
So Hardy seems to be the anomaly. OpenBSD 4.2 failed to install, Ubuntu 7.10 failed to boot the CD. Also Virtual Manager frequently wouldn't start up or shutdown VM's.
So all in all a pretty dismal picture.
