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.
If I start virsh in interactive mode and get a serial console on a VM, then exit the console, then re-enter the console, I get garbage output consistent with two console sessions being started simultaneously.
Steps to reproduce:
1) start virsh in interactive mode
2) start $VM
3) console $VM
At this point console output should be normal.
4) exit console with ^]
5) console $VM
At this point the console output will be garbled. Also, destroying the VM and then trying to get a console hangs (I waited over half an hour) instead of reporting that the VM is down.
tested with PASSED
libvirt-0.9.4-12.el6.x86_64
qemu-kvm-0.12.1.2-2.192.el6.x86_64
kernel-2.6.32-197.el6.x86_64
Steps:
1) start virsh in interactive mode
2) start $VM
3) console $VM
At this point console output should be normal.
4) exit console with ^]
5) console $VM
Actual result
All of the guest starting process could be exactly caught and outputted , there is no garbled output for me .
According to the above , set bug status to VERIFIED
