Subject RE: Unable to attach second disk on CentOS 7 VM

Xen-tools include the required PV drivers and we don't have to download anything for this.
Try attach ISO option on a vm from CS UI and you will see xen-tools iso in the drop down list.

Thanks for the idea. Do the xen-tools include the required PV drivers? 

I know that there is no official rpm of xen-tools so I need to download them and install them
manually, correct?
