Re: [libvirt][PATCH RESEND v10 5/5] qemu: Add command-line to generate SGX EPC memory backend

Since the argument is going to be required I think it makes sense to require it for qemu 6.2.0. Otherwise we could have yet another capability to reflect whether .node attribute is needed or not. But IMO that's pointless because the capability would be set only for one particular release of QEMU (not to mention it's probably impossible to detect whether .node attribute is needed or not).
