I've committed some changes to koan to allow for provisioning of
kemu/qemu guests.
To try this out:
yum install kvm qemu
(Guests will use hardware support if you have it, if not, they'll be
emulated)
koan --server=bootserver.example.org --profile=foo --virt --virttype="qemu"
You do not need to do any thing special in cobbler -- your existing
0.5.0 profiles/trees will work without modification. In my testing, I
installed
a Centos 5 guest inside of F7 -- and as long as you have sufficient RAM,
it seems to work well.
This commit includes the new --virtpath parameter, which is useful if
you would like to specify a location for the images to go. Right now
the default -- which is /really/ temporary, is "/opt/qemu". I can do
better. I also need to test out the partitioning and volume group
management bits with Xen (this parameter supports things like
--virt-path=partition:/dev/sdb1).
The qemu code pays attention to cobbler attributes such as memory size,
kernel parameters, and disk size.
The new parameters such as --virtpath and --virttype will be able to be
set in cobbler, though I intend to keep the overrides available in koan
for at least those parameters. --virttype will default to "xen" as
shipped because that's what we support officially in RHEL, though I
think I'll let the cobbler system default be changeable in
/var/lib/cobbler/settings so you don't have to specify it with each
profile created.
I still need to customize the qemu support a bit more, clean up the
code, and improve the options some, but I just wanted to pass along that
it's there now for those that want to play with it.
