Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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
