Hi,

I am running bhyve on FreBSD 11.1-RELEASE-p4.
I use vm to control the virtual machines.

I have several machines running.
Two of them are configured with the same template, one Linux Mint and one
RHEL 7.4.
Both of them receive their IP address through DHCP.

For some reason the RHEL server is dropping it's address and becomes
unavailable on the network after a while.
When that happens /var/log/messages on the FreeBSD server is spammed with
this:

 dhcpd: send_packet: Host is down
 dhcpd: dhcp.c:3976: Failed to send 300 byte long packet over fallback
interface.

This never happens with the machine running Linux Mint.

dhcpd is running on the same FreeBSD server as bhyve.

This is the output of "vm vonfigure rhel":
uefi="yes"
cpu=2
memory=4G
network0_type="virtio-net"
network0_switch="lan"
disk0_type="ahci-hd"
disk0_name="disk0.img"

xhci_mouse="yes"

Any ideas of what is causing this?
