I think the recent issue was with xend not working.  Did we fix send
and break xl?
Could be. It might also be that that 'xl' never did it the same way
as 'xend' (meaning this might be a XenBus teardown change).

Note also that this is PV guests - and I think most of the testing
had been with the HVM guests with PCI passthrough. So it might be a
seperate issue altogether. Or that nobody tried doing PCI plug/unplug
in the past :-(

I certainly did before my February FOSDEM talk that included driver domains.

In any case, this is a pretty important feature; I think we need to
sort it out before release, so I'm giving it a bug id to track.

Is "pci permissive" set in the global xl.conf file?
No. Let me of course try that.

That really should have to do with getting it working in the first place, not detaching it; but still...

Have you tried this with say, a stock Debian Wheezy kernel?
No. A v3.10-rc4 with Xen 4.3 latest.

Is Debian Wheezy a 2.6.32 kernel?

No, 3.2.
