I installed a fully virtualized VM on my system noted below. To keep it
simple I made it puppy linux. It runs as expected, including successful
it appears that reboots are broken on my system for
paravirtualized systems. I seem to recall the test install of windows I did
about a month ago seemed to work also as it was likewise fully virtualized.

Subject: [CentOS-virt] domU reboot leaves VM crashing continually
Im new to xen virtualization on CentOS, but I have been unable to find the
answer to this problem Im experiencing.
My setup: AMD quad core (64bit), 8Gb ram. CentOS 5.3 dom0, CentOS 5.3
Dom0 is set up with two NICs, the built-in and a PCI card, and I set up xen
bridging on both interfaces.
My domUs seem to boot up fine, run fine, and shutdown fine. However, if I
attempt a reboot operation, they go into a state where they continually
crash on startup. I have been unable to ascertain why this happens, and I
do not know how to fix it when it does happen. So, my question is twofold:
1) How do I get it out of the continual boot/crash cycle? Xm destroy
doesnt work, none of the GUI tools work. So far the only answer has been
rebooting dom0, which is not a good answer L
2) Has anyone else seen this/solved this? Besides being able to
manually fix it from #1 above, it sure would be nice to have it able to
reboot as expected.
I havent worked with any fully virtualized guests yet, but I will try that
pretty soon and see if it evidences the same behavior.

Please let me know what additional information would be helpful or what I
can do to facilitate debugging this issue.
