VMs lose bridged network connection after host suspend/resume

Reported by: VeHav2GoVeeper Owned by:
Component: network Version: VirtualBox 6.1.4
Keywords: bridge bridged disconnected Cc:
Guest type: all Host type: Windows

Description

This doesn't happen every time, but often enough to become frustrating: when I suspend/resume the host, all of the guests (Windows and Linux) are unable to communicate over the bridged network.

What does not work:

  • suspending/resuming the guest
  • restarting the guest OS network services
  • restarting the guest OS
  • disabling/enabling the guest's network adapter
  • disabling/enabling the host's network adapter that is bridged
  • disabling/enabling the vbox bridging driver on the host's network adapter

One thing that did work:

  • connect alternate network adapter on host (eg.: wireless) and set as bridge for VM

Aside from that, the only thing that fully works is to reboot the host, but I have several passwords to enter and dozens of applications to run in order to get my environment setup, which makes frequent rebooting untenable.

This may also provide a clue: when I enabled the host's wireless adapter, the host was not able to receive an IP lease from the router's DHCP server, I had to key in a static IP for the host.

Is there a service or executable I can restart or run to kickstart the bridged networking?

taskkill /t /f /im VBoxNetDHCP.exe

What helps is to change the promiscuous mode in the extended network settings back and forth. Hope this helps.
