Likewise, another virtualization engine, virtual-box, was recently
opensourced.
Virtual-box has the added benefit of device drivers (like VMWare) to
speed things up within the guests. Also, like VMWare, it will use
Pacifica (Intel VT [vmx]) or Pacifica (AMD V [svm]) if available.
kqemu should gain some of that vmx/svm compatibility soon.
For those that didn't catch the 2.6.20 announcement, kvm is _only_
vmx/svm, and there doesn't seem to be any rush to change that,
particularly with kqemu being opensourced.
kqemu, kvm, virtual-box, xen's hvm: the fun common bit between all of
them is QEMU.
There has been quite a bit of virtualization news recently. I'm looking
forward to some great stuff hitting this year.
