Description Gijs Peskens 2021-05-04 15:34:10 UTC 
During some testing I tried moving an interface with an IP configured on it into a vnet kernel, which paniced (I assume, since the machine rebooted) the kernel

Sigh I was tired when I typed this "vnet kernel" -> vnet jail.

i.e.:

create jail with vnet enabled, without interfaces
ifconfig epair create
ifconfig epair0b inet 1.2.3.4/24
ifconfig epair0b vnet yourjail
<PANIC>

I'm unable to reproduce this. Do you have a crashdump, or at least a kernel panic message?
Comment 3 Kristof Provost freebsd_committer freebsd_triage 2021-05-14 07:54:44 UTC 
There's not enough information here to debug. Please re-open when a reproduction scenario or a crash dump are available.
