To be perfectly honest, it is not really a high priority. Our priorities are getting the DomU stuff merged upstream & working reliably and continuing the Dom0 work, since those impact every single user of Xen. Unfortunately PCI pasthrough is quite a niche userbase, so its hard to justify work on it in the short term given limited resources. If someone has skills & time to volunteer to work on the PCI passthrough stuff.....
ouch! a large %age of the boxes we deploy have a firewall/DomU & and a NAS/Domu, each with dedicated, pass'd-thru NICs. without passthru, performance is lousy.
so, iiuc "not really a high priority", i guess -- short of 'growing' someone with the skills -- we're hosed.
the unfortunate irony is we *moved* to Fedora because the passthru support in RHEL was flaky, and Fedora was touted as "the right way to get it". regressing a working feature that differentiates the distro would not have been my first choice ... majority, or otherwise.
PCI passthrough *is* supported in RHEL-5 Xen kernels. There was a bug in the RHEL-5.1 Dom0 userspace, but that is fixed in 5.2. AFAIK, any RHEL-5.x guest supports PCI passthrough.
