It's probably a not so good idea.
Admins restart a host only when there is some kind of manteinance to do.
This means 2 things:- long time before it come up again
- the host'll restart with different feature than before
(increased due to a new feature, reduced due to a regression or a security fix)
Having VMs suspended or hybernated for so long and having them to restart with a different host could be not such a good idea. Even if probably this is not so different than move them to a updated Host.

Google is always a great friend: https://xen-orchestra.com/blog/xenserver-emergency-shutdown/
edit: screenshots are outdated, but the feature is still here (emergency shutdown)

if you don't ask, you won't find out -
To be fair, it's not in the XO doc. We'll correct that!
-
This will suspend and hybernate all the VMs.
But not during a reboot.
Instead allow you to halt all hosts -
@akurzawa hi, I've done it when installing patches before rebooting no problem so far, but as said here maybe is not a good practice.

@xisco is this XCP thing? or citrix?
about pausing VM - this is default behavior in Hyper-V server and is work flawless - restarting server prior to some MS patching - all vm are going nicely to sleep and after boot resumes accordingly.
