maybe i miss something but i see:

if (dbVm != null && (on this host) || (not on this host and up))

so the last part is not protected if dbVm is null
Line 89:                         if (vmData != null) {
Line 90:                             changedVms.add(new Pair<>(dbVm, vmData));
Line 91:                         }
Line 92:                         if (isDevicesChanged(dbVm, vdsmVm)) {
