1110185 – virDomainGetCPUStats returns binary data in error message when domain doesn't exist

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:	libvirt-0.10.2-29.el6_5.10
Doc Type:	Bug Fix
Doc Text:	The UUID (Universally Unique Identifier) is a string of characters which represents the virtual guest. Displaying the UUID on a screen requires correct APIs to present the strings in a user-readable format. Previously, printing unformatted UUID data caused exceptions or incorrectly formatted output. For Python scripts, exceptions that were not handled could cause unexpected failures. For other loggings or visual displays, the characters in the output were jumbled. With this update, the UUID strings are properly formatted and printing them no longer causes unexpected exceptions or jumbled characters on output.
