Public bug reported: This bug was discovered while doing an Ubuntu QA test, "Install (entire disk with lvm and encryption)" for Ubuntu Kinetic. I'm doing this within a virtual machine - the host OS is Ubuntu Studio 21.10 running on an HP Z220 SFF Workstation, UEFI, no secure boot, 16 GB of RAM, quad-core Intel Xeon with no hyperthreading. I placed the VM disk image on a SATA SSD different than the SSD the host OS is installed on.
After following the steps in the testcase mentioned above and rebooting the system, I was presented with a solid black screen. Opening the System Monitor on the host OS revealed that the VM was using almost no CPU. I tried blindly entering the disk's decryption password into the VM by clicking in the black screen of the VM, typing the password, and hitting Enter. Upon doing so, the VM's CPU usage immediately spiked, and I was presented with a login screen in the VM not too long after. I was able to log in and get to the desktop, where I'm currently typing this bug report. Steps to reproduce the bug: 1: Download the Ubuntu Kinetic daily ISO from 2022-05-11. Here's the link: http://cdimage.ubuntu.com/daily-live/20220511.1/kinetic-desktop-amd64.iso 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://iso.qa.ubuntu.com/qatracker/milestones/433/builds/247872/testcases/1451/results Expected results: Upon rebooting in step 25, you should be presented with a field to input the disk decryption password into. Actual results: You are presented with a black screen, but you can blindly enter the password into the VM and get it to boot.
