Sorry that I've just noticed your original post.
You may remember that I've posted elsewhere that I've talked about
being very pleased with core i7-920 supporting a mixture of guests,
with a Radeon video card. All of that reported experience uses
Windows Vista as the host and VMWare software to run the guest
I had previously tried using Fedora as the host OS, and I am now
determined to wait for a viable bare metal hypervisor before trying
any further experiments.
The Windows Vista/VMWare guest setup appears to involve a fair bit of
baling wire and chewing gum, with the need to install VMWare "tools"
that are *very* specific to the guest OS. Windows XP runs noticeably
better as a guest than does Fedora (surprise, surprise). Windows XP
integrates seamlessly with the sound card. For Fedora, the fact that
I don't really need a sound card is a big plus (it works, but it's
For everyday operations, though, it's hard to tell that I'm using a
virtual machine, even when the virtual machine is acting as an
x-server for a remote box. If I were to continue trying to use Fedora
as a virtual host at this point, I'd see it as my contribution to what
is obviously a very immature software technology. The hardware
appears to be more than up to the task.
Odd, I have been running this desktop as virtual since FC6, and under FC13 I
have a number of VMs running which seem just fine, including various Fedora,
CentOS-5, and XP machines. I tried VISTA as a test, and it was clunky, but then
it is on bare metal, as well.
One thing to note, I start VMs from script using qemu-kvm called from command
line. I started doing that back when there was no fancy hypervisor, and it suits
my usage (which is admittedly sometimes unusual). Other than enabling the analog
sound in PA I use no tricks, and run fine on FC1 hosts.
