I've just tried to provision a new VM (via uvtools) using the latest focal kernel (5.4.0-25-generic) and it seems to boot fine with 256MB of memory. However, I haven't tried to do the release upgrade from 19.10 (I'll test this later).
If you have a way to boot into the previous kernel you can try to install the linux-kvm kernel and boot with this one, it has smaller memory footprint and it should be able to boot fine. Then, once it's booted you probably need also a swap file / swap partition to be able to do your normal activities without triggering the oom killer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872535 Title: Kernel panic in 5.4.0-21-generic when try to launch on system with 256 MB RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
