Question: =======
Why is LXD Host unreachable? From my remote workstation having IP address 192.168.0.101/24 I cannot ping LXD Host’s ip address 192.168.0.77.
I see on LXD Host: #ip link show
lxdbr0: <NO-CARIER, BROADCAST,MULTICAST,UP>
Why is virtual bridge lxdbr0 down? What am I missing?
You shouldn’t use the same subnet on multiple network interfaces in the same network stack, in your case both enp4s0 and lxdbr0 are configured with IP addresses in 192.168.0.0/24.I assume.
You should choose another subnet for lxdbr0 and configure a static route to that subnet on the router with the host as gateway.
I do not use the same subnet on multiple network interfaces: LXD Host has its physical interface enp4s0 unconfigured w/ no ip address --and-- its virtual interface lxdbtr0 configured w/ ip address 192.168.0.77/24.
Virtual bridge lxdbr0 is enslaving physical interface enp4s0.
See my configuration files in the initial post.
It looks like virtual lxdbr0 does not use physical interface enp4s0 to communicate outside from the LXD Host.
On LXD Host I see : #ip link show
lxdbr0: <NO-CARIER, BROADCAST,MULTICAST,UP> …
I sit at remote workstation w/ ip address 192.168.0.101/24. and problem is that from remote workstation I cannot ping LXD Host.
