Have a box with a 320GB and a 500gm sata hds'
What is the best method to set this up.
It's a core 2 quad 64bit, with currently 4gb ram (max 8)
I would like it to run Fedora12 32+64 && Fedora13 32+64 && Rawhide.
For trying to reproduce certain bugs on current Releases.
I can add extra drives to box as necessary.
Best base F12,F13, Rawhide?
XFCE is my preferred DE.

Hi Frank,
That should be pretty straight forward. Run the latest stable release on
your host, eg. F13/x86_64 and download the isos you wish to have
installed. The simplest way to do it is probably to use virt-manager to
install the guests with. Depending on your data setup, like if you want
to be able to share data/source code from the host you could export that
to the guests via NFS. In that case you don't need more than say
10GB/guest for the operating system. Add more if you want more data
space in the guest.
General rule of thumb, don't try to assign more vcpus to a guest than
you have physical cores. Use virtio for networking and disk
(virt-manager should either pick that automatically or give you an
option to choose). Second, if you run a lot of large guests at the same
time, you will see the system being sluggish.
For best performance either use a raw partition on the host for each
guest, or a raw image file. qcow2 is a fair bit slower.
In addition, virt-manager allows you to connect to the GUI of each guest
so you can run whichever window manager you prefer.
Cheers,
Jes

Is 150gb HD space enough for a guest,
that way I can put F13.i686 and x86_64 on the same 320 RAW hd.

It's about 50x more than you'll need for a reasonable base install, so
"enough" entirely depends on what the system is going to do. We can't even
begin to guess at that.

Gave up driving years ago, doesn't go with sleeping at the wheel.

Cool, I can fit 3 guest at 100gb each,
overkill I know but hd's are cheap.
Final Question for now.
Can I set the guests up as a softraid raid1 + spare.
Is this something virt-manager could handle?.

Mmmm, you'll have to elaborate on that one. What do you mean, as in
running the disk images as raid? You can do that by creating multiple
disk images and passing them on to a guest as multiple devices, then
setting up the raid in the guest. However for performance / security you
are better off running the raid on the host and just having image files
there. Unless you want it for testing purposes.

Done.
set the soft raid up to mount as: /var/lib/libvirt/images
