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.

Fixed In Version: virt-who-0.17-1.el7
Doc Type: Enhancement
Doc Text:
_virt-who_ handles HTTP error 429 properly When the Subscription Manager load is too big, it might return HTTP error code 429 to rate-limit communication with the client. Previously, _virt-who_ did not handle this error code properly, resulting in sub-optimal behavior. With this update, _virt-who_ now handles HTTP error code 429 properly and retries the communication with Subscription Manager later.

Red Hat Product Errata RHBA-2016:2387 0 normal SHIPPED_LIVE virt-who bug fix and enhancement update 2016-11-03 13:53:39 UTC

Description Radek Novacek 2015-12-01 07:43:50 UTC 
Candlepin has recently introduced rate-limitation for host-guest associations. It returns HTTP error code 429 when the guests (including virt-who) are sending request too often. The clients should increase checking-in interval when they get this error code.

Unfortunately current version of virt-who in RHEL-7 can't handle this kind of reply and it fails with following error:

Support for this error code has been added in virt-who upstream and needs to be backported to RHEL-7. This affects lots of customers.
Comment 1 Chris Arceneaux 2016-02-23 22:30:18 UTC 
Is there somewhere I can find what the checking-in internal minimum is? I had mine set to 5 minutes previously. I've changed it to 1 hour just now to see if that resolves the issue but I'd really like the interval to be shorter than a hour.
Comment 2 Radek Novacek 2016-05-17 13:02:59 UTC 
Fixed in virt-who-0.17-1.el7.
Comment 4 Eko 2016-07-19 09:02:18 UTC 
verified with virt-who-0.17-6.el7.noarch
Comment 7 Radek Novacek 2016-09-29 14:35:47 UTC 
There is a typo in the Doc Text: HTTOP -> HTTP, otherwise looks good. Thanks.
