Hi, I can answer your last question about the virbr0.
In the past we had some issues if vm on another network also uses IP in 192.168.122.0/24. Hence we decided to disable the default network virbr0. you can find the commit in https://github.com/apache/cloudstack/pull/3227/commits -Wei On Sat, 26 Jun 2021 at 03:57, Junxuan Wu <atrocityth...@gmail.com> wrote: > Hi, > > I recently migrated my dev environment of cloudstack to a remote Google > cloud machine.
