No idea, in general I'm going the other way and fighting with getting
connections INTO a VM. :-(

Yes, take a look at the qemu docs. I haven't done it in over a year and
one quick try didn't work, so I'll leave you with that, it certainly can
be done.

You could specify making a partition or device available to the VM as a
device, but the safest way is to NFS mount it, so you don't get multiple
machines stepping on each other.

I've decided to hold off on KVM for a few months at least and stick with
VMware. In fact I think I'm going to buy a VMware Workstation license
when my trial license expires. The raw performance of KVM is better than
VMware if you don't use any virtual IO and it's integrated into the Linux
Kernel so it's worth keeping an eye on. However it's very immature. It
has almost no tools and those that are there don't work very well. On the
other hand VMware is very easy to configure and use. VMware is not
integrated into Linux so it's a less convenient then it could be but it's
still way easier to use then KVM in it's current state. By the time
Fedora 10 comes out I'm hoping that KVM will have reached the usable
state.
