rebooting. I had the line ifconfig_bridge0="addm xn0 addm epair0a up" on
the /etc/rc.conf , and the server went into an infinite crash-reboot loop.

Here is the situation:
I have a VPS server from a well reputed provider (and they deserve the
reputation), running FreeBSD 11 stable x64 under Xen Full Virtualization
(HVM). I have the xn0 interface which is working fine. I intend to use VIMAGE,
so I compiled the kernel, added cloned_interface="bridge0" and restarted the
server. But as soon as I am attaching the xn0 to bridge0, the kernel is
panicking and the server restarting.
Any suggestion/pointer/test-instruction is highly appreciated.
The code crashes at line 427 of sys/netinet/if_ether.c:
stable/11 has problems accounting the outgoing octets of any xn
interface, although this isn't connected to your case.
Just to rule out any uncertainty, try this patch:
See PR 213439,
Note, I'm not a developer nor a committer, just a humble sysadmin.
This problem is unrelated. ARP statistics is global and isn't related to
some specific interface. IMHO, the kernel panics due to missing VNET
context. As I see from the code in sys/dev/xen, it is not capable with

Still we need to address this issue!
Even here in FreeBSD-11 stable I see crashing
of the bhyve.
What I need to help you is what is needed for running gdb ../bhyve ../bhyve.core
What I would like to have, if possible, is running FreeBSD 11 stable on
the server, use vnet/vimage for my jails so I can isolate each of them
from one another.
Currently I am building world with the patch suggested by Trond (started
that before I read the mail from Andrey). But if that is unlikely to
bring a solution, that would mean most people on VPS with jails that are
using Xen are going to suffer from any upgrade to 11 (or having new
servers running 11) -- which is definitely undesirable.
If anyone would like me to run further test on the box, please let me
know what you'd like me to run, and I can come back with the response.
Having a reliable/stable solution is the objective from my end.
Thanks to all for your suggestions/comments.
