Can you share the <interface> configuration for your guest NIC so we
can see how it is setup.
Here we go...
<interface type='direct'>
<mac address='xx:xx:xx:xx:xx:xx'/>
<source dev='enp0s31f6' mode='bridge'/>
<target dev='macvtap0'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x01' slot='0x00'
function='0x0'/>
</interface>
# ifconfig
Both the physical and macvtap interfaces are disconnected (note how
RUNNING is missing):
enp0s31f6: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

# ip link
2: enp0s31f6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc
fq_codel state DOWN mode DEFAULT group default qlen 1000

I can bring up the macvtap interface with the following command (notice
the RUNNING/UP flag):
# ip link set macvtap0 protodown off
# ifconfig
macvtap0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::redacted prefixlen 64 scopeid 0x20<link>
ether xx:xx:xx:xx:xx:xx txqueuelen 500 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 42 bytes 6001 (6.0 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
# ip link
6: macvtap0@enp0s31f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP mode DEFAULT group default qlen 500
link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
However, at the next connection/disconnection of the physical link, the
macvtap interface will go down again.
Regards.
