Description of problem:
The unit for max migration bandwidth should be Mbps not kilobytes/second

Version-Release number of selected component (if applicable):
perl-Sys-Virt-0.9.10-2.el6.x86_64
libvirt-0.9.10-4.el6.x86_64
qemu-kvm-0.12.1.2-2.234.el6.x86_64

How reproducible:
everytimes

Steps to Reproduce:
1. check usage for migrate_set_max_speed and migrate_get_max_speed
# man /usr/share/man/man3/Sys::Virt::Domain.3pm.gz
...
$dom->migrate_set_max_speed($bandwidth, $flags)
    Set the maximum allowed bandwidth during migration of the guest.  The
    "bandwidth" parameter is measured in kilobytes/second.  The 
    $flags parameter is currently unused and defaults to zero.

$bandwidth = $dom->migrate_get_max_speed($flag)
    Get the maximum allowed bandwidth during migration fo the guest.  The  
    returned <bandwidth> value is measured in kilobytes/second.  The
    $flags parameter is currently unused and defaults to zero.
...

2. use set-migrate-speed.pl to set max migrate speed:
# cat set-migrate-speed.pl
#!/usr/bin/perl
use warnings;
use strict;
use Sys::Virt;

my $uri = "qemu:///system";
my $domname = "vr-rhel6-x86_64-kvm";
my $bandwidth = 2;
my $flags = 0;

my $con = Sys::Virt->new(address => $uri, readonly => 0);
my $dom = $con->get_domain_by_name($domname);

$dom->migrate_set_max_speed($bandwidth, $flags);
$bandwidth = $dom->migrate_get_max_speed($flags);

3. use "virsh migrate-getspeed" to check:
# virsh migrate-getspeed vr-rhel6-x86_64-kvm
2

# virsh help migrate-getspeed
...
  DESCRIPTION
    Get the maximum migration bandwidth (in Mbps) for a domain.
...

Actual results:
The unit for max migration bandwidth is kilobytes/second

Expected results:
The unit for max migration bandwidth should be Mbps
