Hi Javier, The output of "onevm show <network id>" does give the correct information, however, I have noticed that in the CONTEXT=[] statement, I have the variable ETH0_NETWORK set to "10.54.136.0", and looking at the context script in the (Debian) VM - /etc/one-context.d/00-network - it seems to take that and use it to generate netmask and default gateway from the VM, thus ending up with the both an incorrect netmask, and an incorrect gateway.
Why would this be happening?

That is, that in the output of "onevm show <vmid>" the context section has the values it is supposed to have.
