Alexander is correct in saying that bridging would allow you to do that.
There are two networking discussed in the guide.
The first is a NAT (network address translation), in which the guests are
given "private" ip addresses and any outbound traffic appears to be coming
from the host machine's IP address. This is the same as the setup on your
ADSL router where the internal network machines get addresses of
192.168.x.x but the internet sees your requests as coming from the IP
address of your router.
There should be lots of documentation in linux firewalling guides under
sections on NAT (or possibly called IP Masquerading in some). Have a look
at these for information on port forwarding to reveal services
inside the virtual (such as ssh).
The other option is bridging. This shares the physical network interface
of the host with the guest. In this case the VM acts as though it's a
machine plugged into the same subnet as the host, its services are
accessible like those of the host and it's as vulnerable to attack as the
host.

As it stands, Fedora 16 (currently using unpatched libvirt-0.9.6) will
be going into beta with QXL video broken for Windows guests, so we need
some kind of Fedora-only patch very soon (see the schedule here:
https://fedoraproject.org/wiki/Releases/16/Schedule - fortunately just
delayed another week)
The original patch in this thread:
https://www.redhat.com/archives/libvir-list/2011-September/msg00534.html
of course doesn't include the above mentioned additional code, and there
isn't a followup patch. It would be very good to push a patch to the F16
git for this so it would hopefully get into the beta, but want to make
sure what I push is the "right" thing, so a "final" patch (and some
testing by people with F16 hosts) would be very helpful!

virt-manager hangs on virt-preview enabled f15
by Gianluca Cecchi
Hello,
with all defined vms powered off, as soon as I start virt-manager and
double click on a vm row, it hangs and only way is to click top right
and then force quit.
I also tried recompiling spice-gtk from F16 source rpm
(http://koji.fedoraproject.org/koji/buildinfo?buildID=261760
btw: on mirrors I still see 0.7.1 for f16 and rawhide..... while
0.7.39 should be in f16 stable???)
so that now I have

Guest can no longer be bootet with libvirt 0.9.6 from virt-preview repo
by Dennis Jacobfeuerborn
Hi,
I just noticed that once I upgrade to libvirt-0.9.6-1 from the virt-preview
repo on my Fedora 15 machine I can no longer boot guests that use virtio
disks. I only get "Boot failed: could not read the boot disk".
Removing the disk and re-adding it as IDE drive allows KVM to boot from the
disk (although the full boot obviously fails due to the hda/vda naming
difference but that's expected).
After downgrading to libvirt-0.8.8-7 again the problem goes away and the
guest boot fine from virtio disks.
Is this a known problem? Do I have to configure something differently to
make this work as it should?
Regards,
Dennis

Dual boot Fedora15/Win7 with VM Win7 too
by David C. Mores
I have a new HP PC with AMD quad CPU that came with Win7 installed. I
installed Fedora 15 by first shrinking the hard drive ntfs partition in
half and letting the Fedora installation set up the dual boot
configuration in the GRUB boot menu. That all works fine. I can boot
either O/S with no problems or side effects.
Now to take this to the next level, I would like to setup a Win7 VM
under Fedora that uses the Win7 installation that is already available
in the Win 7 partition. Running the original Win 7 installation as a VM
guest would be cool - efficient use of storage, the Win7 license and
convenient - along with the existing option to reboot into Win 7. The
Fedora Virtualization Guide documentation does not seem to cover this
case where the O/S install exists before the VM is created.
Can this be done? Have you done it successfully? What are the details?

spicy problems after enabling virt-preview repo on f15

spicec in general...)
Also virt-manager seems quite unstable; two examples in a few minutes
1) totally grey and I have to force quit and restart
2) no double click on a running vm
using strace -p in this case against virt-manger shows a lot fo

Any help to eventually things to pre-configure before enabling
virt-preview on a f15 stock host?

virtio-win 0.1.15 iso missing network drivers?
by Gianluca Cecchi
Hello,
using Fedora 15 + virt-preview, I would like to update drivers for my W7 vm.
It seems that inside the 0.1.15 iso there are no netkvm drivers for
windows 7 (both x86 and x86_64).
Any explanation for this? Where could I download updated ones?
BTW: why its version is less than the .vfd one...? 0.1.15 vs 1.1.16...
I think this can lead to misunderstanding...

Routing only works in one direction
by Philip Rhoades
People,
I have been installing virtual machines for a while on a Fedora 14
x86_64 system (the most recent one was F16 Alpha i686) and I have always
managed to be able to test what I wanted to but ssh-ing from the host to
the virtual machines has never worked (it always works the other way
around). I get:
ssh: connect to host 192.168.122.139 port 22: No route to host
ifconfig shows:
virbr0 Link encap:Ethernet HWaddr FE:54:00:9F:96:2F
inet addr:192.168.122.1 Bcast:192.168.122.255
Mask:255.255.255.0
route shows:
192.168.122.0 * 255.255.255.0 U 0 0
0 virbr0
so why the error message?
Thanks,
Phil.
