Bug 852260

Description of problem:
ith flag Sys::Virt::Domain::AFFECT_CURRENT, set_scheduler_parameters can not work well when domain is shutoff

Version-Release number of selected component (if applicable):
perl-Sys-Virt-0.9.10-4.el6.x86_64
libvirt-0.10.0-0rc1.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. # cat perl-test.pl
#!/usr/bin/perl
use warnings;
use strict;
use Sys::Virt;

my $uri = "qemu:///system";
my $domname = "guest2";
my $con = Sys::Virt->new(address => $uri, readonly => 0);
my $dom = $con->get_domain_by_name($domname);
my %sched_param = (Sys::Virt::Domain::SCHEDULER_CPU_SHARES=>1);
$dom->set_scheduler_parameters(\%sched_param, Sys::Virt::Domain::AFFECT_CURRENT);

2. Destroy domain guest2
3. Run # perl perl-test.pl

  
Actual results:
report error
libvirt error code: 55, message: Requested operation is not valid: domain is not running


Expected results:
Should work without error

Additional info:
When domain is shutoff, virsh command works well
# virsh schedinfo guest2 --current cpu_shares=1
Scheduler      : posix
cpu_shares     : 1
