@scottalanmiller I've recently looked at the SLES installer and it seems it is able to support Xen. Not sure about opensuse.
openSuse Leap has everything like SLES does. It's essentially a straight copy. Suse and openSuse have kept on supporting Xen since the very beginning. They never moved away from it.

I've never used xen so I do not know if XO is able to deal with Xen over suse.
It's not Suse that's a factor. It's that XS has XAPI which is the extra API for management. To use XO, you need XAPI. So if you use Xen in any non-XS configuration, you have to add XAPI support yourself to get those kinds of things.
-
You might want to test openSuse Tumbleweed, too, for the very latest features.

you mean build them from source?

I mean get them. RPM, Source, binary... whatever it takes. You need them from somewhere, though.

I've not added XAPI support onto openSuse, so have no idea what the availability of that project might be.

@scottalanmiller I've recently looked at the SLES installer and it seems it is able to support Xen. Not sure about opensuse.
My idea was: why use XS if I can install it on a minimal suse leap? I've never used xen so I do not know if XO is able to deal with Xen over suse.
This would be a nice way to go out of the really strict/limited apporach of XS. And anyway it would be way more close to what one does with centos minimal install + libvirt/kvm.Currently I'm using hyper-v + altaro. I've just setup a replica server using the build-in replica service and I'm going to test it (and write a little bit about the process). Altaro is great but hyper-v is really MS stuff:
- dynamic memory has frozed ALL of the VMs on my host (even win ones), leading me to go the static memory way.
- everytime I read about issues with a potential update a million of guys jump out of the blue with the wierds issues, scarrying me. I always pray when an update is to be installed.
- performance is not top notch (minor issue here)
- now and then the VM manager freezes...
- and honestly poweshell is way worst than unix-like apps + bash/sh
All in all it seems the classic lack of QA and NIH syndrome from MS. But for sure it does the job and the SW ecosystem is wide.
Updates pretty minor when using Hyper-V Server instead.
Dynamic Memory works great as longs the hyperv-daemons for Linux is installed and also configure memory ballooning.
I have experienced Manager freezing because of antivirus.
PowerShell does take awhile to get use. I've been forcing myself to use PowerShell exclusively. I understood it more than I did with vbscript.

Using XAPI would be cumbersome as @scottalanmiller said, but you can use the very mature and IMHO better libvirt framework, like KVM do! The support for Xen is very good, you should also be able to do almost anything virt-manager support with KVM. The XL toolstack for Xen is mature and is the de facto standard outside of XS.
Ma, dato il tipo di configurazione che stai cercando di metter su, ti consiglio di usare Fedora con KVM più che provare adattamenti: la sicurezza e le features di KVM (nonché le performance) sono ormai pari e volte superiori a Xen.

Yes, but searching for the KB number always raises more issues than on any other platform! Once they had to ask Chuck Norris to stop KBs to create chaos!

In my experience even win server 2012R2 VMs freezed. I think this is an issue with the HW/SW combination. Don't know. But it appens. And on a certified configuration.

Yes, you are right , but hey they say I need an AV on windows
PowerShell does take awhile to get use. I've been forcing myself to use PowerShell exclusively. I understood it more than I did with vbscript.
I've coded in my life (for a few weeks up to a lot of years) in c, c++, python, java, matlab, js and even in bash or VBA! I've debugged a bit of VB and c#. It's almost 20 years since my first attempt with a programming language. No problem with new languages. But honestly my issue with Powershell is exactly this: it seems to me more of a scripting language than a real shell.
If you have used linux utils + shell you can understand what I mean: while PS is powerful, it is way more verbose and programmish than the linux counterpart.

The idea about suse + xen came in mind considering the issues with XS. On the other hand XO features (like incremental backups) seem really interesting.

That's one of the biggest problems with Xen. Some features are from Xen itself and so you want the latest and greatest. Others come from XAPI and XO so you want to go that route. Argh.

@scottalanmiller Yeah I did and it worked great to get it running but I still have issues now connecting from other Domains/Networks even with it. So I RDP onto one of the VM's that has 5nine running to do simple stuff.
Looking at putting a Server in the DC of our new MPLS hosts so might try Hyper-V again for that.
I still love XenServer and XenOrchestra as my one of choice for now. But then i'm only running small Linux/Windows servers on it anyway like Zabbix, Radius, Unifi. Nothing full production like the DC or Dynamics/SQL

Same here, but cautiously watching...
