Hi,
I'm trying to "push" my usb controllers and grahpics into a pvm linux
domU, the graphics bit appears to work just fine :/
I have gone through some of the steps that led some posters here to
success, unfortunately no luck for me.
This is the error I'm getting:
Started domain cent-desk01
rtc: IRQ 8 is not free.
rtc: IRQ 8 is not free.

[ domU just hangs after that ]
but i think the usb controllers start to get reinitialized as the
mouse / keyboard lose power at that point.
I echo'ed each pci id to pciback/new_slot, pciback/bind,
pciback/permissive in that order, using cat shows permissive is set
just fine
dom0 debian etch 2.6.18-5-xen-amd64
domU centos 5.1
xen 3.0.3-1 (holy shit is that old!)
bios iommu enabled (does it matter for pvm?)
(debian etch doesn't recognize the ICH9 components at all, but i don't
care as they'll be mapped to the domU which happens to have the
fitting drivers)

i also tried swiotlb=force (domU crash) iommu=force (same result as
w/o), but i dont exactly know what these do anyway, i tried to stir up
some documentation on those, but turned up quite blank so far.
To me this somewhat feels like not a xen issue dom0 but one in the
domU, still I'd be glad about any input, or hints as to maybe working
around the problem.
Summed what I'm trying to do is to build a loadbalaced (enomalism)
shared root cluster (opensharedroot) of dom0s, where some domUs stay
local to a specific domU, one is the firewall for the non-vlan
external interfaces, and one is my desktop pc for the graphics card.
after successful dom0 boot it's supposed to simply launch a xen
enabled kernel instead of the standard one and otherwise look just the
same, keeping it bootable outside of xen.
So far, it seems possible within a few more rainy weekends, supposing
i somehow get my keyboard activated in the domU :))))
Any hints?
Florian
