From: Christian Kujau on 20 Mar 2010 04:20 Hi there, again a bit late in the game, I tried to upgrade one of my DomUs from 2.6.33 to 2.6.34-git (tried -rc1 yesterday, pulled again today, so I'm on -rc2 now): ------ dom0# xm create sid.cfg -c Using config file "/etc/xen/sid.cfg". Started domain sid ------ Then it just "hangs" there: it won't return to the shellprompt (as if the domU crashed) but it won't connect to the domU console either (as it does perfectly with 2.6.33). And indeed, the domU is listed as running: dom0# (xm list sid ; sleep 3; xm list sid) | grep ^sid sid 55 256 1 r----- 140.8 sid 55 256 1 r----- 144.3 Also, "xm dmesg" is blank and netconsole doesn't work inside a domU, IIRC. Hints how to debug this (besides doing git bisect, again) are very much welcome! Oh, the Dom0 is Ubuntu 8.04 (2.6.24-24, Xen 3.2.0) on a Mac Mini.

And yes, it does indeed resolve the issue, the domU is now booting again. For the record, I've put the .config and dmesg on: http://nerdbynature.de/bits/2.6.34-rc2/xen/ Thanks again!
