Why destroy what you have built already? Just standup ovirt on a separate vm.
It's the upstream for RHEV. It's not a management interface for Xen.

What process are you using to add it through the CLI, I wonder if the same thing is happening when I attempt to setup the newer Xo installations that I've tried.
Just mounting it normally. I just go to /tmp/xo-server/mounts and do
mount -t nfs server:/volume/path remote-#Then click attach in the interface and it attaches.
If I unattach the mount and remount it even through the cli, it won't mount in XO.
Weird, that's not true. It mounted again, but then I noticed it was unmounted (I was running a test backup).
Well this did work once I was under root on my test system. I had to initially add the mount using the web console as ip /path/store
Including the initial / it didn't mount otherwise.

@DustinB3403 and I have a GitHub hosting of the script now. As it gets updated, it will update there.
Is this just for Ubuntu or will it work on CentOS?? (I prefer CentOS know my way round it better than Ubuntu)

Xen Orchestra was built on Debian, I built the installation guide on Ubuntu and have tested it on Debian as well.
If you want to build an installer for CentOS you're more then welcome to, this one was built for the Debian family.

It's Ubuntu specific. Should be adaptable to CentOS, but they don't target CentOS so I would recommend Ubuntu as that is what the XO project tests against. I plan to be doing a 16.04 update very soon, as we need XO up and running in the NTG Lab once it reaches California.

That script seems to have worked fine with 16.04 I have XO up and running. Just need to play now see what it can do

So I've gone through this thread but still a bit confused on Backups.
My plan is to run 7-8 VM's over two XenServers and Starwinds free VSAN. But I want to "backup" the VM's (well at least 3) to a NAS, is this done via the "snapshot" option?

Interesting, why are you using Starwind which requires a Windows VM, on top of the hypervisor, on each node.. that's a lot of Windows overhead and stuff, when XenServer does this natively itself with no need for VMs, licensing or anything. Would be faster and more stable doing it the native way unless you need Starwind features that XS doesn't provide.

Wasn't aware XenServer could do VSAN/Replication so will look into this thanks Scott.

It's called DRBD and is fully automated if you use HA-Lizards' HA system for XenServer.
It's not VSAN, VSAN is conceptually a fallback for when things like DRBD do not exist. This is native RAIN. Full replication at the lowest level of the stack, and presented as local storage, not SAN, on each host. So there is never a network block storage protocol to get in the way like a VSAN has to use.
-
The difference is that DRBD does not do scale out, you need Starwind for that. But for two node mirrored replication, it's unbeatable. It's the same technology we use for storage clustering on all Linux systems.

Yeah I think we are never going to go over 2 hosts for the Citrix farm. So that will do.
Thx again Scott. -
DRBD is used as the base for HA in many NAS storage systems.

Thx again Scott.Just wondering, why do you need shared storage for a Citrix farm? Doesn't that kind of defeat the farm part?
Now that I think about my question more, I guess the shared storage is less about the farm, and more about your VM infrastructure.
But then I wonder, why are you limiting the VM infrastructure to potentially only two hosts?And is something like VSAN really needed to protect a Citrix farm? I thought Citrix farms were like ADDS servers, and typically we don't need VSAN to protect ADDS servers.

I think that you are assuming that Citrix is a proxy word for XenApp, which it often is. But I suspect that it is not, here.

Oh? You think he's calling a XS infrastructure a Citrix farm?

The two server are for Citrix XenDesktop. Each server will have 4 VM's giving 250 users Desktop Sessions (not VDI more RDS). The idea for VSAN/Replication between the two is if one host goes down the remaining host can spin the 4 VM's up so we always have 8 VMs running until the host is fixed.
Is was just going to use XenServer as the Hypervisor as it's FREE and does a lot as @Scott and others keep mentioning
-
Oh, @Dashrender is right then, why use shared storage for a XenDesktop farm? Or, more importantly why HA?

Exactly, why are you using HA? That's supposedly the whole purpose of a Citrix farm, the farm is the HA. Just like multiple ADDS servers are the HA, you don't protect it at the hardware level, you protect it by putting it one 2+ hosts.
-
Because no desktop means no sales and one sale could be £100K so we need all 8 VM's running during office hours.
Yes 4 VM's could I guess run all 250 users for a day but if there is a FREE method of ensuring the VM's are there ready to run in their latest state i'll take it
