Hi,<br><br>We are looking to add new hypercalls to XEN hypervisor 3.4.3 for one of projects.<br>Is there any range of hypercall numbers reserved which can be used to add new hypercalls any third-party developer other than Xen.<br>
Because if we now add a new hypercall (say, with number #60), and in future XEN releases a official patch which also adds a new hypercall with same number (#60), there will be a clash.<br><br>So, could you please advice which of the hypercall numbers (may be a range) can be safely used for our customizations.<br>
<br>Thanks &amp; Regards,<br>VSR.<br>
