I did eventually get it to work by unpacking the tarball and running it from there (it is a simple python script) but the ebuild is no where near ready for amd64. virt-manager has about ~80 deps on my machine and I don't care to install it. I think Ubuntu may be going down that route. [1] The screenshots of this one look promising. virt-viewer: haven't quite figured out how to use this. others?

I had a harder time getting VBox networking to work right. @Bruce: thx for the hint, I will look into that myself and bring the ~amd64 kw to it if it works. @manfred: I didn't think the best of VBox performance. Disk I/O took a horrible hit and compilation was slow. I don't have any concrete numbers and this is my opinion of course but at least I *did* try both ;) Also, you can pass -smp to the kvm arguments and your vm will have multiple processors. This way I can keep my host cpu usage at 100% (if desired) vs 40-50% max with VBox. Maybe there is a way to tweak this in VBox..not sure though. @Cynyr: nat networking worked for me out of the box.

The faq indicates that it should work with kvm too, although it has not been well tested yet. @Cynyr

I looked at writing on in python/gtk but it never got off the ground...
