Things that are still broken:
- dom0 VGA text console doesn't work, only serial console works

OK, Gerd identified a mapping problem that probably explains the lack of VGA. I haven't had a chance to cook up a fix for it yet.

- CONFIG_HIGHPTE=y crashes the dom0 kernel sooner or later, so I'm running 

It's possible this is related.  Well, it would be nice ;)

Otherwise my setup consists of:
- Fedora 10 distribution on dom0, latest updates installed
- libvirt 0.6.1 and related packages from f10 updates-testing (earlier versions 
had a lot of problems)
- F11/rawhide Xen 3.3.1-9 packages rebuilt for F10
- New enough pv_ops dom0 kernel so it has /sys/hypervisor support for 

Missing features:
- blktap (tap:aio). Any plans for this? - PV domU PCI-passthrough?

Yes, both are planned. blktap is on a fairly short list (waiting for blktap2 to land, rather than waste time on blktap1).

I think a lot of the tricky bits PCI passthrough are already done in the form of the rest of the dom0 pci changes, but I haven't looked at pciback in detail yet.
