I did not find it in kvm directory .
The .config file used to compile the kernel. If you didn't compile it
yourself, it can probably be found in /boot/config-2.6.18.x.y.z for
something similar.
What distribution are you using?

Unfortunately the slow network performance and the fact that, on my
setup at least, network io takes 100% of a single core means that kvm is
not currently useful for server use.
Certainly, kvm is slow right now for server use. This will improve
quickly though.

All,
I am experimenting somewhat with kvm on an
ubuntu edgy system, and am now trying to install
a plain ubuntu dapper from CD into a VM.
The problem is that I cannot get past the lilo prompt,
in fact the Qemu process craches immediately after doing
starting up its bios.

Ok. I sure don't know what's wrong on that machine then.
I'll try to come up with a better patch.

Any thoughts?
SMM continues the tradition of making each x86 generation hackier

What happens (probably) is that the virtual hardware unmaps the vga
memory when SMM is entered, and uses the physical memory

Howdy,
The attached patch forward ports the KVM patch to QEMU's CVS. The
only significant change needed was hacking the Bochs BIOS to
dynamically disable SMM support if KVM is enabled. This was done by
using one of the Bochs DEBUG ports. Probably not the best

Applied; thanks.
and I've also created a new
version of the building KVM without gcc 3.x patch.
I'll take a closer look at this later.

There are four issues I can see:

Hello,
I have an AMD machine with 3800+ Dual Core Processor

FC6 (x86_64) is installed on this machine.
This processor DOES support SVM

I had built kvm-7 on that machine.
