[Xen-devel] strange domU problem

["S.ÃaÄlar Onur" <caglar@xxxxxxxxxxxxx>]

Hi;

After upgrading to current xen-3.0.4-testing.hg domU's starts to not working 
as expected, here are the some findings;

* dom0 boot without a problem
* xend starts without a problem
* As soon as "xm create domain", domain enters a blocked state and never 
returns (nothing changes if i use old 3.0.3-domU kernel or new one)
* dmesg, xen dmesg, xen logs shows nothing strange
* Starting another domU while first domU in blocked state unfreezes first one 
for a while and first domU starts to boot but after a while (~5seconds) 
enters blocked state again
* Second domU also enters blocked state as soon as it started
* In order to boot/use first domU ,i have to continuosly destroy/create second 
domU but they always ended in blocked state

Here are the some output

# xm create pardus -c
