Currently yes, as I understand it the virtinst library will have PXE
support in a release soon (at least in F7/F8?), and at that point we can
do fullvirt. Right now, since fullvirt installs require a disk image
for provisioning (they can't just be fed a kernel+initrd), we can only
do paravirt Xen. However, KVM does allow this currently, so there
we are doing hardware. We should have something for Xen soon.
OK, in that case I'll just run paravirtualised machines in the mean
time. I'm sure the performance is supposed to be very similar between
paravirt + hardware virt - can anyone confirm?
2) When not using the xen kernel to do the installation (which I can
do if I create the VM manually) I get the following error:
xend.err "Error creating domain: (2, 'Invalid kernel',
'xc_dom_find_loader: no loader found
Right... for paravirt Xen you have to use a kernel with "xen" in it.
Yeah, thought so, just making sure that when using Xen it was *only*
paravirtualised - hence I tried the non-xen kernel
3) When using the xen kernel to start the VM I get the following error:
xend.err "Boot loader didn't return any data!
I'm not sure what that is, actually. We'd need the logs from
/var/log/xen/xend.log to see for sure. There may also be some
relevant logs in ~/.koan
Attached is a snip from my xend.log. The issue is actually caused by
the following error initially I suspect:
[2007-10-04 17:05:44 2504] DEBUG (XendDomain:960) Creating new managed
domain: vps3
[2007-10-04 17:05:48 2504] WARNING (XendDomainInfo:1114) Domain has

[2007-10-04 17:05:48 2504] DEBUG (XendDomainInfo:1709)

I then get the original error i mentioned when i try to start the domain
manually.
4) Are there plans to further expand cobbler to allow you to select
the number of virtual CPU's available?
That's easy to do, and there was a patch for it at some point -- which I
believe got lost in the shuffle. I'll add it.
RFE filled so I don't forget:
https://hosted.fedoraproject.org/projects/cobbler/ticket/27 :)
Excellent, thanks for that :) Will this be rolled out to the Fedora 7
repos, or is it probably going to be more of an 8 thing?
Are you actually on holiday and working btw Michael? If so, even more
thanks are in order.
