I don't have a Win Server 2012 machine available right now, but I have a Win10 Pro machine with Hyper-V and I was able to boot 4.15.0-45 on a gen1 VM.
Do you think there's any other specific VM configuration that you are using? I will try later with gen2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814069 Title: kernel linux-image-4.15.0-44 not booting on Hyperv Server 2008R2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1814069/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
