So my networking on my host has been extremely slow and choppy on my VM guests. I read somewhere to not use NAT but when I tried to turn off NAT, I could never get and IP address. Turns out that was the fault of lagg.
I have disabled lagg and configured my VMs to use bridging mode and suddenly my host is extremely fast.
Also, when I accidently configured my VM to use iwn0 instead of wlan0, the system hung, followed by a reboot.
So lets sum up the three tips for using VirtualBox on FreeBSD:
- Don’t use lagg on the host.
- Don’t use NAT.
- Don’t configure the guest to use your wireless device using iwn0, but make sure to use wlan0.
