Then vagrant hangs at the point, when it tries to access the VM via SSH in order to configure the VM. At the same time in Virtualbox, when I click on the VM in the list, the GUI of Virtualbox freezes and does not unfreeze anymore. I need to end the Virtualbox Manager Process in Windows Task manager in order to make Virtualbox work again. The Problem occurs with several Vagrant Boxes with recent Ubuntu versions (e.g. ubuntu/focal64, ubuntu/eoan64). It seems to work (at least most of the time) with older Ubuntu versions (e.g. ubuntu/trusty64). I have the feeling that I experience problems with Virtualbox since upgrading Windows to 2004 (Spring 2020 Update) and/or enabling WSL2, but I cannot prove since I haven't used Virtualbox immediately before the upgrade / WSL 2 enabling. Expected bahaviour: ------------------- The Virtualbox GUI does not freeze when I click on the VM in the list of VMs and Vagrant is able to finish the prozess of configuring the VM. Additional Information: ----------------------- - Windows 10 Pro (2004, Spring 2020 Update) - Windows Subsystem for Linux (WSL) 2 enabled - Virtualbox 6.1.10 r138449 (Qt5.6.2) - Vagrant 2.2.9 - Vagrant Box: ubuntu/focal64, 20200605.1.0",defect,new,other,VirtualBox 6.1.10,,,,Linux,Windows
