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.

# virsh dumpxml r6|grep -2 lxc
<console type='pty'>
<source path='/dev/pts/11'/>
<target type='lxc' port='1'/>
<alias name='console1'/>
</console>
5.cannot detach after attach
# virsh detach-device r6 lxcconsole.xml --live
error: Failed to detach device from lxcconsole.xml
error: Requested operation is not valid: device not present in domain configuration
Actual results:
attach success
Expected results:
report error, this console is for lxc, if we try start a qemu guest with lsc console, will get error :

So attach this console should report error.

qemu: output error when try to hotplug unsupported console type
https://bugzilla.redhat.com/show_bug.cgi?id=1164627
When using 'virsh attach-device' to hotplug an unsupported console type
into a qemu guest the attachment would succeed as the command line
formatter didn't report error in such case.
v1.2.12-rc1-3-g860522d
