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 huiqingding 2014-08-15 02:51:29 UTC 
Description of problem:
boot a RHEL7.1 guest with text console, do migration, after migration, the text on text console cannot be displayed normally.

Version-Release number of selected component (if applicable):
src host:
qemu-kvm-rhev-2.1.0-1.el7.x86_64
kernel-3.10.0-143.el7.x86_64
dst host：
qemu-kvm-rhev-2.1.0-1.el7.x86_64
kernel-3.10.0-143.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. boot a RHEL7.1 guest with text console on src host

2. boot the guest on dst host:

3. do migration
(qemu) migrate -d tcp:10.66.9.152:5800

Actual results:
after migration, some texts on the console are not displayed normally, the screenshot before/after migration are as the attachment files.

Expected results:
after migration, the texts can be displayed normally.

Comment 3 huiqingding 2014-08-15 02:54:03 UTC 
I also test qemu-kvm-rhev-2.1.0-3.el7ev.preview.x86_64, also hit this problem.
Comment 6 Dr. David Alan Gilbert 2015-08-07 15:54:48 UTC 
Please retest on 7.2; I know there were some spice fixes that went in; not sure if they are enough to help.
Comment 7 huiqingding 2015-08-12 02:34:05 UTC 
I test this issue using the following version, also hit this problem:

SRC host:
qemu-kvm-rhev-2.3.0-16.el7.x86_64
kernel-3.10.0-304.el7.x86_64
DST host:
qemu-kvm-rhev-2.3.0-16.el7.x86_64
kernel-3.10.0-304.el7.x86_64
Guest:
RHEL7.2
kernel-3.10.0-302.el7.x86_64

The commandline is same as comment #0:

Comment 10 Dr. David Alan Gilbert 2017-03-21 17:13:18 UTC 
Hi, please retest as per comment 9, but just using the current 7.3.z to see if it's the same as bz 1235732.
Comment 11 huiqingding 2017-03-23 01:26:41 UTC 
(In reply to Dr. David Alan Gilbert from comment #10)
> Hi, please retest as per comment 9, but just using the current 7.3.z to see

I use the command line and steps of comment #0 to test 7.3.z:
kernel-3.10.0-514.18.1.el7.x86_64
qemu-kvm-rhev-2.6.0-28.el7_3.8.x86_64

After migration, not hit this issue and the text is displayed normally.
Comment 12 Dr. David Alan Gilbert 2017-03-23 09:06:53 UTC 
Based on comment 11 it seems fixed; the suspicion is that it was the same as bug 1235732
