Description weizhang 2012-04-17 09:26:36 UTC 
Description of problem:
I find it when I test vm installation with perl-sys-virt, after vm finishing installing and shutdown, the perl function get_state() still show that the vm state is running; If I destroy the vm during installation, then get_state() show the vm state is blocked; If I then restart libvirtd, then get_state() will show that vm state is nostate

Version-Release number of selected component (if applicable):
perl-Sys-Virt-0.9.10-4.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. run script with perl-sys-virt
2.
3.
  
Actual results:
get_state() return confusing

Expected results:
get_state() can return the real vm state when domain is shutdown

The 'get_state' function doesn't do anything special - it just calls into the virDomainGetState() C API. So if there is a flaw here, it is probably in the libvirt layer.

Can you try creating a simple demo in C that reproduces the problem, or see if 'virsh dominfo' shows the same behaviour

At the same time, run dom->get_state() return 0, which means nostate
Comment 4 RHEL Program Management 2012-05-03 05:11:01 UTC 
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
