You can also use the current sources from kvm's website (I am
currently using kvm-16 w/ add-scsi patch). It's easy to setup unless
you have gcc >3.x _and_ 64-bit userland....

Also, compiling patched qemu with gcc newer than 3.x means you can run
only w/ kvm enabled.

I never noticed that - I had troubles with march cd's 9pcf kernel, but
using an old one from ca 2005 solved the problem of hangup after
"running /bin/rc".

On the other hand, I use AMD's SVM instead of intel's VTx, and they do
differ in some places, as qemu needs to put most of real mode through
emulation.

Unfortunately I haven;t had time to do any benchmarking. The only one
I could say I have performed is that after switching to SCSI I have
been able to sit through the whole installation process without
falling asleep...
