I tried 11.1 amd64 iso installation in the same guest, and em0 didn't work. I tried 10.4 amd64 iso installation in the guest and em0 dhcp worked fine. So it appears that em0 driver of 11.1 is buggy?
How to rescue my kvm guest which has already upgraded to 11.1?

主旨: em0 doesn't work after upgrading from 11.0 to 11.1
After the first reboot after upgrading my freebsd (in a kvm guest hosted on CentOS 6) from 11.0 to 11.1, em0 couldn't get IP address from DHCP:
em0: Watchdog timeout -- resetting
em0: link state changed to DOWN
em0: link state changed to UP
The above messages are repeated in dmesg.
I reran "freebsd-update install" to complete the upgrade and rebooted the host again, and the issue was still there.
Networking worked perfectly fine before the upgrade. /etc/rc.conf:
