So blame me for that, not XS.
Oh I blame you, don't worry.
That's good.

Don't get me wrong, I really like XS...
As a HyperV guy, if HyperV was setup like XS (instead of needing all the the domain BS just to connect) it would be much more successful, my 2 centsWait... what? You don't need to be connected to a domain to use Hyper-V? Where did you get that idea from?

LOL.
All good. It was a learning process.
I have the ability to learn new stuff where I work.
I'm still not 100% sure what I would do. Now that it's working, it's fine. Not a blip in sight thus far.

@coliver Let me re-phrase that.
You need a domain to take full advantage of the Hyper-V stack (is that better?) -

Why can't you just install Hyper-V & connect with a browser like ESXi or XO?

What does this have to do with a domain? Even when connected to a domain you'd need Hyper-V Manager to do any management. This was a design decision, that was the wrong choice in my opinion, but has really nothing to do with functionality.

Because Hyper-V is lacking and needs commercial third party tools to get to that point. That's a big deficiency in the system.
XS has that too, but XO provides it and for free. So that's why XS+XO as a bundle is what we often refer to.

XS may not be complete, but isn't it the "most complete" of all options available?

With XO it certainly is a very complete solution.
Without XO, we would be using unitrends (or hyper-v and some backup appliance)

Nothing, but I assume he means without a domain setup, remote connectivity is a pain in the ass to set up.

I agree with the OP - Dustin's SR problem wasn't solved by going to a USB stick based install. Did it ultimately make it easier, perhaps a little, but the install was still not easy.
But, at the same time I don't know that ESXi or Hyper-V would be any easier.
Can anyone speak to installing ESXi or Hyper-V to local OBR-10 5 TB or larger and having access to the remaining storage for VMs upon completion of installation?
With any luck, XS v7 has fixed this.But back to the OP's point. XS does seem to expect one to know a lot of linux based commands and lookup many xe commands to do things that are completely possible to be done within the GUI in ESXi and Hyper-V.
For example, importing a SR(datastore). In XS you must use the command line for this. In ESXi, this can be accomplished completely in the vSphere GUI.
And speaking about importing a SR - ESXi will see and import the VMs from the SR automatically, recreating all of the VMs on that SR (it does ask first though). in XS you have to have previously backed up the metadata, then restore it. The restore might be along the same lines ESXi, but the backup process? That doesn't exist in ESXi. -
I can say this, coming from ESXi to XenServer was almost painless, it saved my arse. But please oh please learn about XO because I had to get help from the community because I had a poorly thought up backup plan (aka didn't make it that far) and it came back to bite me in the arse.
I think install XenServer compared to ESXi is about equal except for I can install to ESXi to a USB like it requires nothing
That had to be my biggest draw to ESXi. Outside of that, I mean managing XS is actually kinda straight forward but I think the way the gui works its better than ESX it just takes getting used to.Adding hard drives is my current dilemma
thats where in my test environment I'm getting painnnnnnnnnnnn. But once you put it on a proper raid / server you should be fine. -
Hope you don't mind some questions.

Did you use XO at all before you realized your backups weren't there?
I think install XenServer compared to ESXi is about equal
Did you use local storage? If so, how large is/was your SR?
except for I can install to ESXi to a USB like it requires nothing
That had to be my biggest draw to ESXi.Actually, install XS to USB is as easy or easier than installing ESXi to USB.
Outside of that, I mean managing XS is actually kinda straight forward but I think the way the gui works its better than ESX it just takes getting used to.
When you say it's easier in XS, is that in XC or XO or both? What makes it easier/better? Did you ever have to remount a datastore in ESXi compared to doing so in XS?
Adding hard drives is my current dilemma
thats where in my test environment I'm getting painnnnnnnnnnnn. But once you put it on a proper raid / server you should be fine.Did you ever add additional storage in your ESXi - if yes, was it easier/harder? What about doing this in XS is hard/painful?

More complete than other options. What else comes with as many pieces as XS does, at least when XO is included?

No, I was just testing it. I had used it 1 year prior, I used Ghetto method before.
Small storage just under 600 GB / SSD
Yea installing ESXi to usb is so easy I wish they all could be so simple.
It is easier to me but I have used all 3 - Hyper-V, ESXi and XS and between the 3, I favored XS. But if your use to windows tools I find it hard to believe one wouldn't love hyper-v and 9nine tools. I did have to remount the data store and it was painful because I didn't have a proper backup, I still made it work but wow I had some downtime. Had I spent more time getting used to XO I wouldn't have had the issue.
Adding storage to ESXi was pretty straight forward. I used iscsi, local drives, raid 1, raid 10. I went nuts. That was for testing purposes and for learning.
When I do my entire infrastructure over, I'm going full XS+X0 with Windows Server Data Center 2012 to as of now, just 1 host with a minimum of 32 GB of RAM with RAID 10 Storage hopefully using 15K drives. I have to shoot for the moon because i'm part of a non profit. My storage needs are kinda paltry. at the moment 1-2 tb is almost more than enough for all my VMs and really I could get by with 1 TB. My actual file server is where I'm rethinking my strategy as I split my nas using iscci to handle some of FS requirements and instead will stop us using my for split storage (vms/shares) and let it just be for backup.

KVM. Qemu and libvirt do pretty much everything. Qemu even does dirty bitmap for incremental backups.

Libvert is an API, though. That's like XS with XAPI. What does the GUI for a cluster look like with KVM and libvert?
