[Xen-devel] shutdown/migration stop working on paravirt domU

[Vasiliy Tolstov <v.tolstov@xxxxxxxxx>]

Hello. Today i'm try to research, why most of our vm (pvm) not
shutdown correctly (we use shutdown with timeout, then it arrives we
destroy vm), and write simple test case to check that domU watches
works correctly:

xenstore write /local/domain/DOMID/control/shutdown testflag;
xenstore read /local/domain/DOMID/control/shutdown

If userspace watches works correctly - xenstore read returns empty,
becouse domU kernel respond only to known actions and printk and clean
path on unknown actions.
I can't see difference in various kernel versions
(centos/opensuse/debian and other), we use oxenstored old version
(that shipped with 4.0.1_21326_06-0.4.1 on sles)
How can i debug this issue and get more info on this problem?
P.S. Some domains, that has small uptime respond to my check and
shutdown/migrate correctly.
