Pre Xen-4.14 streams will not contain any CPUID/MSR information. There is nothing libxc can do about this, and will have to rely on the higher level toolstack to provide backwards compatibility. To facilitate this, extend the static_data_done() callback, highlighting the missing information, and modify libxl to use it. At the libxc level, this requires an arch-specific hook which, for now, always reports CPUID and MSR as missing. This will be adjusted in a later change. No overall functional change - this is just plumbing. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
