Bug Description
This bug was discovered while doing an Ubuntu QA test, "Install (entire disk with lvm and encryption)" for Ubuntu Kinetic. I'm using the same host system specs as in this bug report: https:/
While running the test, in step 14, immediately after clicking "Install Now", the VM appears to be processing the information its been given, when suddenly there's a sharp graphical glitch. It's hard to describe, it's sorta like the screen gets torn and stretched left and right for a second or something - you'll have to actually reproduce the bug to get a good idea of what it's doing.
(Edit: Upon further inspection, the Ubiquity window is resizing itself such that it fills the entire available horizontal area of the screen, at least on the screen size that virt-manager provides by default. It resizes like this, snaps back to normal position, resizes again, then snaps back again.)
Steps to reproduce the bug:
1: Download the Ubuntu Kinetic daily ISO from 2022-05-11. Here's the link: http://
2: Open virt-manager, and ensure that you have a connection to "QEMU/KVM User session". (If you don't, you can create this connection in virt-manager by clicking "File", "Add Connection", selecting "QEMU/KVM user session" in the "Hypervisor" drop down, then clicking "Connect".
3: Create a new VM under QEMU/KVM user session. Select the Kinetic ISO downloaded above, set the OS to "Ubuntu 21.04" (that's the newest version my virt-manager recognizes), and give it 4 GB RAM, 2 CPU cores, and 20 GB of disk space.
4: Follow the steps in this test procedure: http://
Expected results: In step 14, after clicking "Install Now", the VM should pause for a bit, processing the data you've given it, and then the screen should advance without any glitches.
Actual results: After clicking "Install Now", the screen throws a fit for a bit before going back to normal. Everything seems normal after the glitch.
