Subject Re: VM from ISO cannot execute restoreVirtualMachine
Date Fri, 13 Dec 2019 13:48:17 GMT
Hi Jerry,

I think this is because of the way a VM is tied to its root disk, and how a root disk is chained
to its template.
VMs created from ISO do not have such a chain.

Technically, it shouldn't be an issue to swap out the root disk entirely, though...

Regards,
Gregor

Subject: VM from ISO cannot execute restoreVirtualMachine

Hello All
When I analyzed the restoreVirtualMachine API, I found that If the VM is from ISO, newTemplate
can only be ISO when executing restoreVirtualMachine.

Why do we have such a design?

>From our application scenarios (I think most of them are the same), the VM created by
the user through ISO may need to be reinstalled through template later.
