I am running Xen 3.1.2 from Gentoo, tried 3.1.1. 32 bit PAE as I wrote in the previous post > > I am running Xen 3.1.2 PAE I never had any problem (at least THIS problem) with any PV DomU (2.6.18, 2.6.20, 2.6.21, 2.6.23-RCs and 2.6.23.1). The problem started with 2.6.23.3 and today I finally found time to track it down. This only affects PV domU, so I don't undestand your question about serial console of Dom0. The symptom is (with a lot of subjective judgment) when there is a lot (or too quick) output on the console of the domU (hvc0 connected with either "xm crea file.cfg -c" or "xm cons id") the whole PV domU hangs. It will really hang at random places, sometimes right after init and sometime after I logged in and just generate some ouput (on hvc0) like "find /". IIRC I have never seen a hang before init. When it hangs there is no output on console any more and network to that domU is dead too, nothing affects dom0. "xm list" still reports the domU as "r", nothing special in the logs (of dom0 xen logs) and no OOPS nor panic reported in the domU. It's seem that it's running in a infinite loop. So, I can make screenshots, but they won't tell you anything, the is no message, it's just dead. Gentoo's xen is just a src tarball made from the mercurial repro, w/o any patches (AFAIK). cheers Ming-Wei Shih
