QEMU vs. VirtualBox

"Why is it that the U.S. Government always releases a slew of RFPs just before Thanksgiving? I've been swamped working on proposals since the third week of November, but we got the last one submitted just before Christmas so it's back to normal (or what passes for normal around here) for a while.

"I thought I'd take this relatively quiet period to do a quickie comparison between a couple of virtualization tools: QEMU and Oracle's VirtualBox. For the comparison I chose to install virtual guest instances of Ubuntu 10.10 desktop from a downloaded copy of the iso. The host system is an AMD 64-bit machine that is also running Ubuntu 10.10 desktop. Here's the kernel version of the host at the time of this writing: 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux. I used VirtualBox 4.0 for this comparison."
