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:
When booting RHEV-H on some hardware, libvirtd fails to start correctly.

This has been simulated on a virtual machine with an ide disk and a physical machine with a sata disk

from /var/log/messages:  Aug 26 11:41:10 localhost libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory

The failure of libvirtd to start causes ovirt-post to wait until a timeout is reached.  This causes a large number of messages in ovirt.log like:

Aug 26 11:41:10 Waiting for libvirt to finish initializing...

Version-Release number of selected component (if applicable):
RHEV-H 6.0-13

How reproducible:
Intermittent, always on some machines

Steps to Reproduce:
1. Boot RHEV-H iso
2.
3.  

Actual results:
On some hosts, libvirt fails

Expected results:
libvirts starts everywhere

Additional info:

Could not find keytab file is just informational, we're not configuring libvirt for gssapi authentication.

Real root cause is:
stat("/etc/pki/CA/cacert.pem", 0x7fff2812a680) = -1 ENOENT (No such file or directory)

/etc/pki/CA/cacert.pem -> /etc/pki/vdsm/certs/cacert.pem

but /etc/pki/vdsm/certs/cacert.pem does not exist

Workaround is to comment out line in /etc/sysconfig/libvirtd

LIBVIRTD_ARGS=--listen # by vdsm

Dan, why does vdsm need libvirt RPC, isn't it using local unix socket connection to libvirtd ?

libvirtd only needs the --listen argument if someone is going to connect to it remotely over TCP/TLS. AFAIK, VDSM is always running locally using the UNIX domain socket, so this shouldn't be required.

We have to --listen for migration, aren't we?

If using the P2P or TUNNELLED migration methods, then yes you need libvirtd to listen on TCP.
