Kernel 2.6.29 with Andy's rebased patches seems pretty stable in QA.

Boris.

I think 2.6.27 is already out of date and you should start with 2.6.29
using my rebased patches, people have been using them since I did
2.6.25 and 2.6.29 is the most stable one yet, as Boris said in another
thread the xenbits 2.6.27 tree does not shutdown cleanly but 2.6.29
does, I'm sure that could be fixed but right now I dont know of any
issues with 2.6.29 at all, so why not make the jump to the current
stable kernel :).

XCI should update to 2.6.29 as well.

I use pci passthrough with a pci express usb2 card, I also use scsi
passthrough with a ultrium tape drive, usually running several windows
hvm's and a couple of 2.6.29 pv domU's as well, no problems.

Andy
