screenshot for white screen
With latest 1.3.0 release of gtk-vnc we now honour the empty password again correctly, so we wouldn't hit this specific problem. *** Bug 1941264 has been marked as a duplicate of this bug. *** Too short on time to fix this in 8.7. We can either backport or rebase gtk-vnc fix but in 8.8. I'll assign it to myself. 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. |
Description of problem: virt-viewer display a white screen after input an empty password for a vnc vm in kiosk mode Version-Release number of selected component (if applicable): virt-viewer-9.0-10.el8.x86_64 libgovirt-0.3.7-4.el8.x86_64 gtk-vnc2-0.9.0-2.el8.x86_64 How reproducible: 100% Steps to Reproduce: 1. Prepare a vnc guest with authentication required. # virsh dumpxml rhel8-vnc --security-info --inactive ... <graphics type='vnc' port='-1' autoport='yes' passwd='aabb'> <listen type='address'/> </graphics> 2. Open the vm by "virt-viewer $guest -k" in the kiosk mode, and then input an empty password after the authentication dialog pops up. $ virt-viewer -c qemu:///system rhel7.9-vnc -k Test result: After I input an empty password on the authentication dialog, then click "OK". virt-viewer will show an error message as follows: ------------------------------------------------------ Unable to connect to the graphic server 127.0.0.1:5902 Unknown authentication failure: %s: Weak encryption key ------------------------------------------------------ Click 'OK', then virt-viewer will display a white screen, details please see the attachment. What's more, without in kiosk mode, if I input an empty password, then virt-viewer prompts the above error message, but after click 'OK', virt-viewer will exit silently. Actual results: As described. Expected results: virt-viewer should get another chance to retry again in kiosk mode. Additional info:
