My experiment in using Fedora 10′s built-in virtualisation technology (based on KVM and qemu / kqemu) to install OpenSolaris didn’t go too well! I find the emulator to be just too slow for my taste, but I’m not sure if I had it configured properly.
So I installed Sun’s VirtualBox instead. As you can see I have it running 2x virtual machines: an Ubuntu Server 8.04LTS VM and an OpenSolaris 2008.11 VM. Both are installing concurrently, and my machine seems to be holding up ok (Load average is around 2 to 3 … I hit 11 earlier on while creating the disk images yikes).
So … try out virtualisation with Fedora’s built-in tools. But be mindful that they seem to work best when virtualising Linux / Fedora. It’s very slick if you want to create lots of mini-Fedora’s in your main Fedora install. This is a boon for developers who like to tweak their systems, this gives you a sandbox within which you can do what you like without harming your main Fedora install.
If you have slightly different requirements you may want to try VirtualBox. Be careful though! VirtualBox’s license prohibits certain uses, so for hardcore server virtualisation heavy-duty workloads you’ll probably want to use KVM and qemu / kqemu after you’ve tested it out with your VirtualBox on localhost.
