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 Radek Novacek 2015-03-10 12:39:07 UTC

virt-who should be rebased to latest upstream version.

There are lots of improvements and optimizations in the upstream repository since version that is in RHEL-7.1. I would highly recommend doing a rebase here.

There's a more recent version in RHEL-6.7 that has quite a few improvements, I would be nice if customer can use them also in RHEL-7.

Comment 1 Radek Novacek 2015-06-23 13:36:11 UTC

Virt-who is now rebased to 0.14 upstream version: virt-who-0.14-1.el7.

Comment 3 John Call 2015-07-21 19:06:13 UTC

Radek,

I'm trying to read the source code and find the VMware optimizations that were made.  I'd like to see the query / queries being sent to vCenter.  Would you please tell me where to look?

Thanks,
John

Comment 4 Radek Novacek 2015-07-30 06:53:52 UTC

John,

you can find all the code for handling VMWare in this file:

https://github.com/virt-who/virt-who/blob/master/virt/esx/esx.py

Optimizations in this version are basically three:

* Simplify the inventory traversal - not all the objects in the hierarchy needs to be obtained as we're only interested in host/guest association (see buildFullTraversal method in that file)

* Use WaitForUpdatesEx method instead of RetrievePropertiesEx to get only updated data not all of them. This also allows to listen for updates instead of polling.

* Do not download vim schema from ESX and have local (stripped down) copy instead.

Is this answer enough or do you need some more details?

Comment 5 Liushihui 2015-09-23 08:13:17 UTC

Verified it on virt-who-0.14-8.el7.noarch since the package got rebase and there are no known regressions. Therefore, verify it.
