VirtualBox is only nice because of its GUI. Otherwise, KVM or XEN
outperforms it a lot, especially on I/O. Also, VB is convenient because
of its bridging thing which works even on WiFi. Unless I'm mistaking,
Xen can't do bridging on WiFi (I'd be *very* happy to be wrong here,
so if I am, please let me know!), and NAT is always annoying me,
which is why I continue with VB for my SID VM.

Anyway, thanks for the hint, I may give (another) try with KVM. Is there
any good GUI that I could use for it (that would work in Squeeze)? Does
it performs a lot faster if I give it a full LVM partition as HDD, or I wont
see much difference with qcow2? I mainly know Xen a lot, and (a bit less)
KVM on the command line, but it'd be nice to use a GTK/Qt GUI too.


P.S: Sorry for the noise to those who don't care, I quite know it's a bit
OT for -devel, but it would really improve my work to have better VM tools.
