Pressing Ctrl-o on a xen guest console is the equivalent of the magic

      If I press the sysrq key combinations, while attached to the guest
with "xl console", Dom0 responds with the appropriate message, but the
DomU guest does not acknowledge the sysrq keys.

If you are logged in via the dom0 console to run xl console to get the
guest console then I think dom0 will eat the Ctrl-o. Not sure if
something like Ctrl-o Ctrl-o will work. "xl sysrq <domain> <key>" should
do the same sort of thing I think.


Otherwise I'm completely stumped. It's probably worth going back to the
data sheet and making sure everything matches in the DTS, in particular
for virtulisation extension related things which might not be used by
native Linux (e,g, the vtimer interrupt SPI number etc), but really
that's getting a bit desperate.


     The guest doesn't respond to any of the sysrq key combinations, I
tried with both of the methods.

Which is expected because the console is not yet setup.

Based on the log you provided earlier, I would go start to check if the
guest receive the interrupt.

On the xen console (CTRL-a three times) you can type 'q' it will print
all the IRQ present in the LRs and which IRQ is pending for a given domain.


I've attached the full log from the domain dump below. But the interesting part of the log is:

(XEN) Rangesets belonging to domain 1:
(XEN)     Interrupts { }
(XEN)     I/O Memory { }

Perhaps I am interpreting this incorrectly, but it would seem that no interrupts belong to domain 1?
