It's still very slow. When I don't attach a serial device like you gave an example for to the virtualbox, it still has that 90s pause between mentioned 'printk' lines during booting and booting is slow in general.
When I do attach the serial device, it still panics the first time, but the whole thing is so fast that vagrant doesn't notice or times out. So that setup is now workable. Still doesn't explain why it behaves so strange without a serial device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874453 Title: ubuntu/focal64 very slow to boot and reboots once To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1874453/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
