Windows sleep breaks network hotplugging

[bomvir]

I have a windows 10 host system with archlinux as guest. Both operate using virtualbox 6.0.12.

In virtualbox, I have set up two network interfaces

1. Bridge
2. Host only adapter

The network bridge usually operates either on a USB-C docking station or the laptops own network interface depending on where I am working. So far, changing the bridges' interface (docking station vs built-in) seems to work fine. However, if I meanwhile put the windows asleep, e.g., through closing its lid it seems to break.

Here is what I mean with break: The bridge network (when connected to either the docking station or the built-in adapter) obtains an IP from a DHCP which offers IPs in range 172.28.0.0/16. If the above mentioned problem occurs (putting windows asleep and changing the bridge's interface e.g. from docking station to built-in or the other way around). The linux interface is not able to obtain an IP (it seems to default to an IP starting with 169.xxxx) and also restarting the dhcp client does not change this. The only thing that seems to work is to shutdown and start the VM again.

Addendum: I believe there is a correlation with an error shown in windows event viewer:

1. This sounds like a possible duplicate of #13466, #14208, #15308, #16077, #16338, #16382, #16973, #17126, #17459, possibly others...

2. No, the error in the Event Viewer is not related to your problem. See ​ID Event 12 for VBoxNetLwf.
