[lxc-users] lxc network create - macvlan

[Ron Kelley]

Good suggestion, but same result:

lxc network attach QA-Server-03:vxlan.1101 QA-Server-03:centos-vm4
error: not found


On the remote server (QA-Server-03):
----------------------------------
root at QA-Server-03:~# ip link |grep 1101
4: vxlan.1101: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

The network interface is definitely there.

I have a number of vxlan interfaces created via the “ip link” command and would like to create the corresponding LXD networks without having to create separate profiles.  I tried the commands "lxc network create vxlan1101 type=physical” and "lxc network create vxlan1101 nictype=macvlan”.  Each time, I get "error: Invalid network configuration key:”
