VirtualBox 1.6 is out. Note that now you can use Mac OS X and Solaris as a host platform. Naturally, having Mac OS X support excites me.
I tried installing a Ubuntu 8.04 server guest. Found a tiny issue – 64-bit guests aren’t supported yet :( So I pulled in the 32-bit ISO, and that installed just fine. Note that PAE support for guests exist now, and this is a good step in the right direction.
Sun’s building an OpenxVM community, which currently focus on xVM and xVM VirtualBox. It also harnesses technologies like Open Service Tag. All in all, I think a lot of MySQL users should be interested in virtualization, as there is a growing amount of hardware out there with many, many cores available for use.
Installing Ubuntu 8.04 server and getting past the kernel not booting
This is more of an Ubuntu problem, than a VirtualBox problem, but I faced an issue:
The kernel requires the following features not present on the CPU 0:6 Unable to boot - please use a kernel appropriate for your CPU
Turns out, the problem was the wrong kernel was installed. Rescue Ubuntu, and install linux-generic. For reference, look at Unable to boot 8.04 Alpha 3 Server install on laptop and also the fix.
