      Hello all, looking for feedback as to a challenge I'm experiencing when migrating VMs from Xenserver 6.5 to XCP-ng 8.2.1. The exported vms fail to start and have the error "Boot device:Hard Disk - failure: could not read boot disk".The methods I have used to migrate are taking a snapshot of the VM,create a template from that snapshot, export that template to XCP then create a VM from it. The newly created VM will not start for some VMs. The only common trait that the VMs have is that they are Linux but they are diffrerent distros. I have tried removing xentools then trying the same but the issue still remains.

      Any insight or alternatives on how to move these VMs will be appreciated

        Without more info it's hard to help.

        Those VMs are in HVM mode already in 6.5?

            I would boot them with a live CD and check if the disks are readable inside the VM.

            Alternatively, it's a boot order issue, or something like that.

              @olivierlambert This was resolved by editing the disk position. The disk position on XenServer was xvda and changing it to 0 resolved this.
