Hi @weizhouapache - yes the addHost ssh issue is fixed with the changes to
sshd_config
- Thanks I've verified the -F option with qemu-img on Ubuntu 16.04 - you're
right. That means we don't need to explicitly deprecate 16.04 wrt these
changes. But I'm okay to drop 16.04 support in future releases (4.16 maybe)
- Yes, in my testing I had added cloudbr0 before adding the host
On further testing my colleagues (@shwstppr) found an issue with newer qemu
when trying to take a volume snapshot:
```
