Ok, I added the kernel modules lines in %files section of spec file and
built successfully kvm-36 with
./configure --qemu-cc=gcc34 --prefix=%{_prefix}
then I installed the rpm overwriting the default kernel modules and I'm able
to run with smp 2
I successfully booted an F8 live x86_64 rescue cd ima

invlpg shouldn't fetch the "src" address, since it may not be valid,
however SVM's "solution" which neuters emulation of all group 7
instruction is horrible and breaks kvm-lite. The simplest fix is to
put a special check in for invlpg.
Also, remove the unused invlpg member of struct kvm_arch_ops.
We don't update the vcpu control registers in various places. We
should do so.

SVM gets the DB and L bits for the cs by decoding the segment. This
is in fact the completely generic code, so hoist it for kvm-lite to use.

This patch is in QEMU CVS and allows network boot to work with newer BIOSes.
It was originally written by Bernhard Kauer and committed (and modified) by
Thiemo Seufer.

In general, the BIOS, VGA BIOS, and option ROMs are not required to be multiple
of page sizes. This means that phys_ram_size may not be a multiple of page.
Address this at the kvm_create() level to make things simplier for future
callers.

Make sure to copy the option ROMs into physical memory so they're visible to
KVM guests. With the older BIOS, this allows -boot n to work although the CVS
BIOS does not work.

"-M pclite" requires -kernel, requires kvm. Also changes --enable-kvm
to --disable-kvm (it's enabled on supported archs, so we need a disable
not an enable flag).

This currently doesn't us
Hi,
It's a pity not to use a host CPU feature if it is available. This patch
exposes host CPU features to guests. It allows fine-tuning the presented
features from the command-line.
The code could use some serious clean ups, but I think it is interesting
enough right now. I'd be happy to hear you

Some hardware and software systems maintain page tables outside the normal
Linux page tables, which reference userspace memory. This includes
Infiniband, other RDMA-capable devices, and kvm (with a pending patch).
