Linux host freezes with bridged adapter and apt

[gabrc]

My Linux (Fedora 33) host freezes whenever I enable bridged adapter and the guest transfers (some) data.

Steps to reproduce:

1. Install an Ubuntu 20.04 server guest
2. Go to Guest settings, Network, Attached to, Bridged Adapter
3. Run an apt install command on it. I was following [these instructions](​https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-quickstart).
4. The host completely freezes, and I'm forced to reboot.

I've installed some server software (Jitsi Meet) and now it freezes even on guest boot.

Some hardware details:

Similar to https://www.virtualbox.org/ticket/7879, but that bug is already resolved.

The Jitsi thing is unnecessary. I just installed an Ubuntu 16.04 LTS VM, changed the network setting to Bridged Adapter, and ran sudo apt upgrade, and my host froze as well.
