*******************************************
It stops responding at all as 3 days ago.
Just the same picture :-
PV DomU CentOS 5.2 has been tested with new kernel
During shutdown mentioned DomU usual sequence of daemon's messages
drops into stack trace with following messages at the end:-
xenbus_dev_shutdown: device/vif/0 timeout closing device
xenbus_dev_shutdown: device/vbd/51712 timeout closing device
System halted.
OK, so this appears on the domU console? And at the same time, the host
becomes non-responsive? Are there any other symptoms?
Bellow follows my message to you sent on 3/14/09
The bug is old.
I do have null modem cable ( 2 m.) . Setting up serial is quite possible,
but not right now. Boxes are located in different places.
If the host just stops responding, then getting the Xen serial console
may be the best way to diagnose it.
Does it also happen if you remove the vifs from the domU config?
Does reverting changes 8c7e11b6b89b3054623bc26bf6bbbda3ffa0ee18,
8b0ddbff9bf6cd8acb881a6296ca5069723f61b1 and
043854ee604d2b49d4def5ac215925296b64b391 help?
