vb543 Posted April 3, 2021 Share Posted April 3, 2021 Hello! I have a VM that's giving me some trouble. The issue started after an unclean shutdown. When starting the VM, I can get to grub just fine - but after the CentOS grub I just get a solid underscore on a black screen. I can also see that one of the unraid hosts CPU cores is stuck at 100% usage when this occurs. Any suggestions for getting this VM working again? Thanks! Quote Link to comment
Leandres Posted April 7, 2021 Share Posted April 7, 2021 I have the exact same problem after updating to. 6.9.1. My Ubuntu VMs start but all the CentOS VMs stuck with a blank screen after grub. This is an issue. Quote Link to comment

Interesting, I thought my problem was related more so to the unclean shutdown - but I did do the update to 6.9.1 during all of that as well. Quote Link to comment
vb543 Posted April 14, 2021 Author Share Posted April 14, 2021 Doing some troubleshooting, I created a new VM with just a live boot of CentOS 7 attached to the VM and it too would not boot past the underscore. I suppose this rules out my VM being the issue and this more so looks like an Unraid / KVM issue. Quote Link to comment
Leandres Posted April 14, 2021 Share Posted April 14, 2021 Yes. I did a roll back to 6.8.3. My CentOS VM's are working again. 1 Quote Link to comment
vb543 Posted April 15, 2021 Author Share Posted April 15, 2021 Cool, can confirm rolling back from 6.9.1 to 6.8.3 resolved this issue. Hopefully they can get it patched in a future update. Quote Link to comment
