hanmaan Posted March 4, 2022 Share Posted March 4, 2022 Trying to start up a VM in UnRaid - can't seem to get it started. I tried to setup GPU passthough first, mucked around trying to setup SteamOS, reset it back so I could try to just work with only the HVM to get a Ubuntu VM going. I went into the BIOS, enabled VT-d, tried to bind the GPU to VFI0, enable unsafe interrupts, reverted all the above then tried to setup a new VM. I created the VM with only one CPU, launch it using the VNC video card and try to build the VM with the Ubuntu 20.04.3 ISO. I get the initial GRUB menu, then it tries to verify the contents (I skip it), then the screen goes to black. The mouse cursor spins, I can hear the printer reacting to the OS booting, but I can't see what, if anything, is happening on the UI. Any suggestions? tower-diagnostics-20220303-1933.zip Quote Link to comment

hanmaan Posted March 5, 2022 Author Share Posted March 5, 2022 This doesn't look to be an issue with Unraid - looks more like its specifically Ubuntu 20.04. Once the splash screen tries to come up, the display disappears. I switched to a 18.04 guest to build the VM and VNC is fine. The issue might be related to this https://askubuntu.com/questions/1316746/no-video-on-ubuntu-20-04-minimal-vm-via-virt-manager, but not sure what steps to take to get the guest further along before the display cuts out.

Solution hanmaan Posted December 7, 2022 Author Solution Share Posted December 7, 2022 (edited) Okay, revisiting this because I ran into issues with Ubuntu 22 as well. Looks like the issue was not setting enough RAM. I set the minimum RAM value too low, 1GB. I bumped to 4GB and all is well. 😅 Edited December 7, 2022 by hanmaan Better explanation of my error Quote Link to comment
