I'm not able to add a new hard disk with xen orchestra.

[ziomario]

Hello.

I'm trying to add a new hard disk (/dev/sdb) to a vm in xen orchestra,but I'm not able to find it. Let's see that I'm running xcp-ng nested with xen-hypervisor and libvirt. When I go in the xen orchestra management,in the disk section,I don't see the disk sdb that I have added in xen + virt-manager + libvirt. Check the images below :

thanks.

Can you explain your setup again? Which hypervisor / os are you running on bare metal? You are running XCP-ng nested under libvert? XO is running under libvert or XCP-ng?

Do you see the new drive when you do an lsblk in the xcp-ng host?

On baremetal there is xen 4.10 + ubuntu 20.04. I'm running a domain 0 on a xen enabled kernel. On top of this I created a new vm with libvirt with the iso image of XCP-ng. When I do "lsblk" I see one only disk : the xcp-ng.img IDE DISK 1

Is your XO running from xen inside libvirt? Or is it running from inside XCP-ng?

Also from the screen shot, your IDE 1 is to a file path "/etc/xen/xcp-ng.img" with a size of 50GB, but your IDE 2 is to a device "/dev/sdb" with "Sconosciuto" size (no idea what that means), may be try mounting the device to a mount point and pass that in to XCP-ng instead?

No. Xen orchestra is installed on the host OS. And on top of the host OS I have installed libvirt + xen + virt manager and I have created a virtual machine of 50 gb with the xcp-ng iso image. How can I pass /dev/sdb as a mount point in XCP-ng ? this is what I'm not able to do.

dimensione storage = sconosciuto --> size of the storage = unknown.

First thing you need to check if the problem is with passing the drive to XCP-ng VM, like Biggen said, try lsblk inside xcp-ng VM (there is an option to go to shell in the installation menu if you haven't installed XCP-ng. If the XCP-ng VM only sees 1 device then it is a libvert/virt manager issue.
