vSphere bootstrap fails with ssh key error

Newbie here, I’m trying to juju bootstrap myvsphere --config datastore=storage --debug and it is failing with
connection attempt for failed: No RSA host key is known for and you have requested strict checking.

It seems to create the vm fine but just repeats that message forever instead of proceeding, any ideas?

Sorry to hear that you’re having trouble. It looks like Juju is having trouble setting up networking.

Could you please provide some more information about your environment? Which versions of ESXi, vSphere and Juju are you running?
