VNET Failure in all jails

[phomchick]

I had a perfectly fine PLEX instance operating in a jail. But I changed the NIC in the machine and all networking to jails now fails.

When I try to start the jail it fails with this Error: [EFAULT]Stopped plex due to VNET failure

If I create a new jail, networking doesn't work in it, either.

The last thing I see in /var/log/messages when booting the system is:

I'm fairly knowledgeable about IP networking and think I could fix a problem if I could figure out what is wrong.

Can some kind soul(s) suggest some debugging steps I could start on?

Thanks!

P.S. This is on my FREENAS 11.3-U5 system

If the new NIC is a different driver or has changed numbers, you'll need to edit the jails to use that new NIC... maybe it was em0 and now ix0.

It may also be that you need to redefine bridge0 to include your new NIC as a member (best done in Network | Interfaces with all jails stopped... shouldn't be an issue if they won't start).

Thanks for the suggestions. I'll give it a try.
