        restart of the host?

            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:

            1. long time before it come up again
            2. 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              edit: screenshots are outdated, but the feature is still here (emergency shutdown)

                  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.
