ad 1. yes they can, if you look in the ticket there is a part of
description that describes this possibility. But that said I don't see how
restore is going to be hindered if the vm was created using a full clone. The
image is not deleted.
ad 2. No it is only marking templates for gc and not touching any cleanup
process, it relies on the regular process to do the actual cleanup. The benefit
is that short lived templates that will be replaced by cron jobs for instance
will be cleaned without having to wait until the VMs cloned from it are all
gone (on a per primary store basis btw)
ad 3. Yes so far it is I have not studied other hypervisors on this area.
The code is now in the vmware plugin but not tightly coupled to the vmware API
so generalizing it shoud be rather trivial.
ad 4. the host scan task was an empty placeholder with only todo. The
vcente clusters are not scanned for new hosts atm. If you look at the old code
you can find that the task consists of only a comment:
```
private Runnable getHostScanTask() {
return new Runnable() {
@Override
public void run() {
// TODO scan vSphere for newly added hosts.
// we are going to both support adding host from CloudStack
UI and
// adding host via vSphere server
//
// will implement host scanning later
}
};
}
```
