[lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[Ron Kelley]

hmmm, seems you are running the “original” version of lxc and not the new lxc/lxd software.  Please ignore my comments then…

# lxc profile show
The program 'lxc' is currently not installed. You can install it by typing:
apt install lxd-client

Maybe that's part of the problem?  Am I missing a package?  Here are the packages I have installed for lxc:

# dpkg -l | grep lxc | cut -c1-20
ii  liblxc1         
ii  lxc             
ii  lxc-common      
ii  lxc-templates   
ii  lxc1            
ii  lxcfs           
ii  python3-lxc

Next I deleted that container and went back to the first host, and it failed.  Lastly, I tried the above steps on multiple hosts and found that it works fine on some hosts, but not on others, and I have no idea why.  On hosts where this fails there are no error messages, but the container can't access the network, and nothing on the network can access the container.
