I've confirmed that the latest Vagrant box published has the fix. I've also confirmed that users can overwrite the default passing of the serial console to a File::NULL and write to a different file.
For everyone affected, run a `vagrant box update` on Focal boxes. This will grab the latest box. If you cannot update your base, using the workaround of attaching a NULL handler will work. This is documented in the code attached to this MP, as well as below Vagrant cloud link to latest: https://app.vagrantup.com/ubuntu/boxes/focal64/versions/20201012.0.0 configuring a NULL file handler ``` config.vm.provider "virtualbox" do |vb| vb.customize [ "modifyvm", :id, "--uart1", "0x3F8", "4" ] # Create a NULL serial port to skip console logging by default vb.customize [ "modifyvm", :id, "--uartmode1", "file", File::NULL ] end ``` ** Changed in: cloud-images/focal Status: Confirmed => Fix Released -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
