I am now noticing it :-(.
As Anthony noted in V1, libvirt uses LIBXL_API_VERSION and currently has it set
to 0x040500. I'm attempting to bump libvirt's minimum supported Xen version to
4.9.0 and for that would use 0x040800, but it's not possible without this
commit
backported through 4.9 and picked up and released by all the downstreams.
Any ideas on how to use the APIs changes through 0x040800, but avoid the ones
introduced in 0x041300 would be much appreciated.
Regards,
Jim
