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.

Comment 9 zhoujunqin 2015-04-13 11:07:30 UTC 
I can reproduce this issue with package:
virt-viewer-2.0-4.el6.x86_64

Steps to Reproduce:
1. check the display resolution of the vm: (1027*768)
2. zoom out more than 10 times
3. check the display resolution of the vm, resolution has changed to (2024*770).

Then try to verify with new build:
virt-viewer-2.0-5.el6.x86_64

Steps:
1. check the display resolution of the vm: (1027*768)
2. zoom out more than 10 times
3. check the display resolution of the vm. 

Result: Display resolution of the vm keeps, not change.

But when i try zoom out more than 10 times, then use mouse to drag the guest window to a larger one, the guest display will turn dark, and showing "Waiting for display 1...".
I cannot connect to guest graphics again until restart guest.
so please help me have a look of this issue, thanks.

Hi,

According to your comment, this bug is verified.
The problem you described is not related to virt-viewer (and I could reproduce it using previous versions), it is qxl bug that was fixed by xorg-x11-drv-qxl-0.1.1-17.el6

Thanks for your confirmation, Pavel Grunt.
After i update to xorg-x11-drv-qxl-0.1.1-17.el6 on my guest/host, i cannot reproduce "black display" issue, and since this bug issue has been fixed, move this bug from ON_QA to VERIFIED.
Comment 13 zhoujunqin 2015-05-14 07:38:46 UTC 
Try to verify this bug again:
virt-viewer-2.0-7.el6.x86_64

Steps:
1. Prepare a health guest(installed with rhel6.7 snapshot-1), check the display resolution of the vm: (1027*768)
2. zoom out more than 10 times
3. check the display resolution of the vm. 

Result: Display resolution of the vm keeps, not change.

So keep this bug in VERIFIED status.
