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 Han Han 2019-12-25 04:01:10 UTC 
It could be reproduced on rhel8.2-av:
libvirt-5.10.0-1.module+el8.2.0+5135+ed3b2489.x86_64
qemu-kvm-4.2.0-4.module+el8.2.0+5220+e82621dc.x86_64

+++ This bug was initially created as a clone of Bug #1786413 +++

Description of problem:
As subject

Version-Release number of selected component (if applicable):
Desktop:virt-viewer-7.0-9.el8.x86_64 spice-glib-0.37-1.el8.x86_64
Hosts: qemu-kvm-4.1.0-20.module+el8.1.1+5309+6d656f05.x86_64
libvirt-5.6.0-10.module+el8.1.1+5309+6d656f05.x86_64

How reproducible:
50%

Steps to Reproduce:
1. Prepare a vm on an virt host. Prepare migration for two hosts.
Replace the SRC and DST host for migration in migrate.sh. Replace SPICE_SERVER with your spice console url of your vm. Prepare an USB device on your desktop.
Prepare to gather coredump and log:
# cat /etc/libvirt/qemu.conf
gluster_debug_level = 0
max_core = "unlimited"

# tail /etc/libvirt/libvirtd.conf
log_level = 3
log_filters = "1:qemu 1:libvirt"
log_outputs = "1:file:/var/log/libvirt/libvirtd.log"

Then restart libvirtd.


2. Run ./migrate.sh to start migration loop. Run run.sh to start remote-viewer connnects

3. When remote-viewer has connected the vm, click File --> USB device selection --> select your desktop usb device to enable usbredir. 
Continue above in step3 until the vm crashes.

Comment 3 Ademar Reis 2020-02-05 23:11:31 UTC 
QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
Comment 4 Xueqiang Wei 2020-03-18 05:42:42 UTC 
Set priority to low. If I was wrong, please correct me.
Comment 7 RHEL Program Management 2021-06-25 07:30:43 UTC 
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
Comment 8 yduan 2021-07-27 09:33:24 UTC 
This is a corner case and hard to reproduce, so agree to close it from my perspective.

What do you think? @dgilbert
Comment 9 yduan 2021-08-02 08:08:44 UTC
