Hi all,

Sorry for being so terse in the last post. It has been a year since I
used LXC, and everything worked easily then.  Now, with a new Fedora 26
system, it is not straightforward. How would you troubleshoot this?


# brctl show

bridge name    bridge id        STP enabled    interfaces
virbr0        8000.525400c7428b    yes        virbr0-nic
# lxc-checkconfig
<all enabled>

# lxc-create -n crowdsr -t fedora

# lxc-start -n crowdsr -F
lxc-start: conf.c: instantiate_veth: 2669 failed to attach 'vethMU7OO1'
to the bridge 'lxcbr0': Operation not permitted

brctl shows only virbr0; you are trying to attach to lxcbr0 which, apparently, doesn't exist. I thought lxc created that but you can add it with

  brctl addbr lxcbr0
