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.

Comment 3 RHEL Program Management 2010-02-17 18:39:08 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 5 Daniel Berrangé 2010-02-26 17:14:23 UTC
Built fix into libvirt-0.7.6-3.el5

Comment 6 Daniel Berrangé 2010-02-26 17:14:51 UTC
That version should of course have said libvirt-0.7.6-3.el6

Comment 8 Matěj Cepl 2010-02-27 10:33:43 UTC
Well, I cannot even test whether this was fixed because with

[root@johanka ~]# rpm -qa libvirt\* qemu\*
libvirt-0.7.6-3.el6.x86_64
qemu-kvm-0.12.1.2-2.17.el6.x86_64
libvirt-client-0.7.6-3.el6.x86_64
qemu-img-0.12.1.2-2.17.el6.x86_64
libvirt-python-0.7.6-3.el6.x86_64
[root@johanka ~]# 

I get this when starting a virtual machine from virt-manager:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain
    vm.startup()

Snap1 contains an update of the libvirt package to
libvirt-0.8.0-3.el6.x86_64.  This update contains the upstream fix for the
issue and I can no longer reproduce the problem.

Comment 16 Kirby Zhou 2010-05-17 04:15:56 UTC
How can we get libvirt-0.8.0-3.el6.x86_64 ?

Comment 17 Daniel Berrangé 2010-06-07 15:21:30 UTC
FYI this bug is a result of QEMU changing to use  bytes instead of kilobytes in the balloon monitor command. The corresponding change to libvirt was missed, so all guests got ballooned to unusably small memory sizes.

Verified PASSED with libvirt-0.8.1-8.el6.x86_64.
- kernel-2.6.32-33.el6.x86_64
- qemu-img-0.12.1.2-2.73.el6.x86_64
- qemu-kvm-0.12.1.2-2.73.el6.x86_64

Change this bug status to VERIFIED.

Could you also verify virt-top:

Comment 22 releng-rhel@redhat.com 2010-07-02 19:29:16 UTC
Red Hat Enterprise Linux Beta 2 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
