Looking at the output of dmesg, there is a clear hint of what might be
wrong; it lists several (>10) of the following messages:
[ 3.957006] pcieport 0000:00:01.0: device [8086:0d01] has invalid
IRQ; check vendor BIOS
[    3.957018] pcieport 0000:00:01.0: can't find IRQ for PCI INT A;
please try using pci=biosirq

Additionally, i found some more strangeness in the dmesg output:
[    3.725793] pci 0000:06:00.0: BAR 15: can't assign mem pref (size
[    3.725796] pci 0000:06:04.0: BAR 14: can't assign mem (size
Also repeating several times for multiple devices.
Could this be related to the problems i see?

This while booting the same kernel (3.13-rc1) without xen works fine.

With all of the above - posting just snippets is not going to suffice
if you want any help with this. Please attach full logs at maximum
log level: hypervisor, dom0 kernel, and natively run kernel (either
the same binary as used for dom0, or making sure the configs are
sufficiently similar).


Thanks for your response, i wasn't sure if this was the right place to
address this, so i kept my initial mail short. However I would indeed
appreciate any help that can point me into the direction of a more
useable xen installation on this system.
So brace yourself for some information ;-)

output of xl dmesg:
Looks like the top part is already gone, and i've no way to capture
this via serial port.
I can take some boot camera shots if that is usefull though.

sync_console is quite unnecessary, especially if you are not using a
serial port.

You can use conring_size=<num> to make the Xen console buffer larger. I
would suggest 128K.

Hmm, perhaps I wasn't doing it right, but i couldn't get the conring_size parameter to work as expected. However, having the source at hand, i rebuilt the hypervisor with a larger (128k) default buffer size, which did yield
a full xl dmesg output:
