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.

Memory statistics are currently disabled in qemu-kvm; hw/virtio-balloon.c contains the following two lines:

/* Disable guest-provided stats by now (bz#623903, bz#626544) */
#define ENABLE_GUEST_STATS   0

I'm not sure what the complete story behind this is since both BZs are currently marked as closed.

From qemu-kvm mainstream discussion I understand that because of regression issue they have disabled this feature. Any idea when it will be implemented ?

And can we have some meaning full information displayed till this comment implemented ?

something like below :
--> "Currently this feature is not supported."

Thanks

Hello Redhat

ANy updates?
Comment 7 Amit Shah 2011-05-30 10:33:58 UTC 
Bug 626958 tracks re-adding virtio balloon stats.  Adam Litke from IBM was pursuing the fixes upstream.  It looks like this won't be ready before the new QAPI is merged upstream.  Marking as duplicate of the other bug.
