How does Xen Orchestra work.

Biggen

Runs as a VM either through their appliance (XOA) or through a dedicated Linux VM. You have to build it yourself if you are running it through a Linux VM. It’s referred to as XO Community Edition if done that way.

Can’t be installed to the host directly.

Thank you so much @Biggen. I think I was coming to that conclusion last night that whatever happened it was going to be installed as a separate VM. I'm guessing that means I need to set the VM where XO is running to autostart if I was a web GUI to be accessible whenever XCP-ng is running.

The other part was that XOA was having trouble with the install on my particular machine.

@Jarvar said in Xen Orchestra vs. XPG-ng Center:

Failed: HVM is required for this operation.

Can you describe your hardware? Does it support virtualization? Is it enabled in the bios?

@Danp
I don't have a bare metal system available for it right now. I did in the past, but it seems like some things have changed.
I am running it in Virtualbox 6.0.14. Under Settings->System->Hardware
Virtualization is enabled, but the nested feature under processor is greyed out.
I have many other VMs already working with Virtualbox, from Ubuntu, CentOS to Windows.
Thank you so much for chiming in.

You can install XO in whatever VM you want (even not hosted on XCP-ng, doesn't matter) as long as you can connect XO to the target pool/host (in Settings/server, you'll enter the IP address). You could even install XO on a RaspberryPi if you like

If I installed XO on a different VM, then both would have to be on and can talk to each other in order to administrate XCP-ng. I'm just trying to figure out what the best options right now.

Initially I had set my drives to have 100GB of space, after install it showed I had 58GB free. and now after install XOA it shows 14GB free. I had 2x 100GB drives installed as Software Raid1.
Somehow I need to free up some space...

Check https://github.com/xcp-ng/xcp/wiki/Requirements

The free space (beyond system partitions) can be used as a local storage.

@olivierlambert
Which one is the system partitions?
I am SSH'd into the system and this is the output from lsblk

olivierlambert

/ is the root partition, /var/log is in another dedicated one.

Jarvar

@olivierlambert
Is there a list of commands in which I could use to navigate XCP-ng without a GUI using just the SSH or command line?

I removed the defunct XOA VM which was taking up 20GB, but it still shows only 14GB free out of 58GB

I think I saw somewhere that XCP-ng is closely related to Centos? or Debian... Is that correct or not really?

Thanks.
