RE: [Xen-users] Problems creating a Fedora 14 domU using XCP 1.0and xe

Hi Joe,

Sorry for the delay. I forgot one step: you need to change the boot loader from 
pygrub to eliloader. I can't remember the exact param name right now, but it 
should be obvious from looking at xe vm-param-list. Hope that helps.

Hi Mike:

Just a quick follow up. It was trivial to get things working using NFS
-- thank you. But I still can't get the http boot to work. Could there
be some sort of bug or am I just missing something?

Hi Mike:

Setting "other-config:install-methods=cdrom,http" didn't seem to work.
It may be that I didn't do it correctly so ran "xe vm-param-list
uuid=$uuid" to verify. The output is shown below. Apparently I am still
missing something. Do you have any ideas that might help.

  It's probably the documentation's fault, not yours ;)

RHEL 6 x86_64 may also work, but 'Other install media' is often your
best bet.

At this point, you'll also need to update other-config:install-methods
to include http. Otherwise, it will just try to boot from the cdrom,
which is empty.

# xe vm-param-set uuid=$uuid  other-config:install-methods=cdrom,http

If you've got an ISO image on your local network, you can also just boot

from that. You can export the directory containing the ISO as an NFS
share, and then use `xe-mount-iso-sr host:/ISO-directory`. Once you have

the ISO directory mounted as an SR, you can then add the Fedora ISO to
the VM as a CD:

# xe vm-cd-add vm=test device=3

While it would work, I wouldn't recommend putting the ISO directly in
dom0, because we only give that filesystem 4GiB to use, and it'll ruin
your day if you run out of space on dom0.
