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

["Joe Linoff" <jlinoff@xxxxxxxxxx>]

Hi Mike:

Thank you! I am going to try both approaches today:

1. update other-config:install-methods to include http
2. nfs mount of the iso

Cheers,

Joe

  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
cd-name='Fedora-14-x86_64-Live-Desktop.iso'

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.
