Just a quick FYI re: installing FC16 pv under xen-4.0.3-1.fc14.x86_64, which
probs applys to Debian.
I installed FC15 first. Then I installed FC16 over the top and told Anaconda
to use the existing parts.
Here's the script I used:
#!/bin/bash
virt-install \
--paravirt \
--name test \
--ram 1024 \
--os-type=linux --os-variant=fedora15 \
--file /dev/XenVG/test \
--graphics none \
--extra-args="console=hvc0 serial rd_NO_PLYMOUTH nogpt" \
--location http://bckup2007.wwe.com.au/iso/
I mounted the FC15 iso first. Then after the machine came up I killed it,
mounted the FC16 iso and installed again. Tell Anaconda to use the existing
partitions.
Finally have an FC16 pv machine that boots with the old pygrub and seems to
work. Obviously the GPT stuff isn't going, which is the root cause here.
The pv machine overcomes my hvm issue where yum update kills the host when it
goes to upgrade glibc in the domU.
Hope this helps someone, 'cause it took all day to figure it out :-)
