Hi.
Is it possible to PXE XenServer domU with cobbler? I've been looking
around but have somehow missed documentation on this one...

I've tried with "cobbler buildiso", but the iso won't boot in
paravirtualized environment, only when domU is in HVM mode...

That's correct I believe for Xen in general. PXE's usually only available
in HVM mode, but not in para mode.
You might need to build the machines in HVM mode and then have some kind of
a trigger to have the host switch the mode? I haven't done it, but just
thinking it might be a strategy to look at.

Well I don't necessary need PXE, I can boot live CD, but how to force
'cobbler buildiso' to build paravirtualized kernel/initrd into it's
generated.iso?!
I would rather not have to manually move from HVM to paravirt, if it's
possible.

I dont think that's up to cobbler
Just add a another distro object with the proper kernel/initrd's

When you imported the distribution, cobbler should have created a version
of the distro/profile that ended with -xen. Use that instead and you should
be good to go.

Hi,
may I ask for what you need that exactly? I always use koan for XenPV, and think its
really convenient. koan --virt to install new machines over the wire and --replace-self on
existing machines for reinstallations. Since that works flawlessly, I've never used
PXE on VMs anymore.
But still, you can use pypxeboot for Xen machines, although I wouldn't know why.
Greetings
André

Yeah, problem is that koan can't manage XenServer AFAIK?
