OS: Ubuntu 16.04.1
Issue: When trying to create a VM with Citrix XenServer (version 7), error "Failed to create root disk". The VM is created on the XenServer but with no HDD attached. I can create VMs manually using xencenter.
Output: Creating virtual system with Citrix Xen .. .. creation failed : Failed to create root disk : Failed to create partition : Error: Error informing the kernel about modifications to partition /dev/sm/backend/b958d5ab-470b-5519-39e8-6f37b464e2c0/cef74117-a7 -- Invalid argument. This means Linux won't know about any changes you made to /dev/sm/backend/b958d5ab-470b-5519-39e8-6f37b464e2c0/cef74117-a7 until you reboot -- so you shouldn't mount it or use it in any way before rebooting. Error: Failed to add partition 1 (Invalid argument)
