I've not been keeping up with developments on PCI passthrough, it last
worked for me in 3.2.0, unfortunately 3.3.0 broke my setup ("pci:
SSSS:BB:DD.F must be co-assigned to the same guest with SSSS:BB:DD.F"
and then when I did try co-assignment of the devices I got the
spurious error "unsupported format character ':' (0x3a) at index 6").

Now I'm trying to catch up with recent developments. I've tried 3.3.1
and it's still not working, but at least the spurious error is now
being reported properly as "pci: SSSS:BB:DD.F: non-page-aligned MMIO
BAR found".

I see Yuji has been doing work with reassigndev/guestdev to realign
these devices, is there anything required within xen for these to
work, or are they purely dom0 changes? I might try to apply the
patches to my CentOS 5.2 dom0.

Is there anything else related to PCI passthrough expected in 3.4.0,
is the timescale still roughly end of March? Is there a release
candidate tag for it on xenbits yet?
