I recently discovered 'savefallback' in grub which I did not know about. |
| 2 |
I'll assume you're using that but again, I haven't seen your grub.conf. |

Dan Farrell made an intresting point about boot log and showconsole, but |
| 5 |
I assumed you were already using that. But I still don't that will help |
| 6 |
you because your problem appears to be one of the following: |
| 7 |
|
| 8 |
* Grub is not loading your kernel and is falling back (same as my |
| 9 |
original theory) |
| 10 |
* Your kernel/hypervisor is loading but is crashing immediately. |
| 11 |
If the Xen hypervisor is crashing you really need the console. |
| 12 |
AFAIK there's no option to log. The only option you really have |
| 13 |
is whether or not to immediately reboot when it crashes. If Xen |
| 14 |
is loading successfully then it loads your dom0. If that's |
| 15 |
crashing it's probably crashing immediately (i.e. not even |
| 16 |
mounting root). If it is the dom0 then that seems to be the case |
| 17 |
since you can't find any record of it having booted. If you |
| 18 |
crash before you mount root read/write then showconsole and |
| 19 |
bootlog are useless. |
| 20 |
|
| 21 |
All things said, I'm still guessing that it's either a grub problem or |
| 22 |
Xen doesn't like your hardware. Xen is picky about hardware and |
| 23 |
sometimes you have to turn on/off things in the BIOS or as a parameter |
| 24 |
to Xen (like the ACPI controller) but it's going to be hard to guess |
| 25 |
without an error message and I'm betting that error message appears |
| 26 |
before bootlog/showconsole take effect. |
