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.

Debug info from virt-manager
Description
The MAC address of cloned guest should be the same as customized from virt-manager,also no error shows when set the same address as another guest
Version:
virt-manager-0.10.0-5.el7.noarch
libvirt-1.1.1-11.el7.x86_64
How reproducible:
100%

2. Right click the guest,click "clone","Clone virtual machine" dialog pop out.
3. On the dialog,from "Networking",click "Details",a new dialog "Change MAC address" pop out.
4. Input a new MAC address or just keep the original default MAC address,click "OK".
5. Click "clone".
6. After clone is finished,check the MAC address of the new cloned guest,it's not the same as you set in step 4.
7. If set the new MAC address as the same address of original guest,no error occurs,while create a new guest from virt-manager,set the fixed MAC address as one which has been used by other guests,error will pop out:
"Mac address collision":"The MAC address '*******' is in use by another virtual machine."
Actual results：
As description.
Expected results:
The MAC address of cloned guest should be the same as customized from virt-manager and error shows when set the same address as another guest
Additional info:
1.From virt-manager debug info,the newly set MAC address appeared in Clone guest xml,however,it set an random MAC address when create the new cloned guest.
Attached the debug info,my customized MAC address is "52:54:00:ce:20:00".
2.The issue can not be reproduced on rhel 6 system.
3.MAC address can be set successfully from virt-clone command.
# virt-clone -o test -n newtest --mac=54:52:00:ccd:aa -f /var/lib/libvirt/images/testtest.img

virtinst, clone: use the specified MAC address for the new VM
Prevent setup_clone from changing the self._clone_macs list so that
further calls will access the same data.
