Please open bugs for these issues. The CPU features/flags is an important feature that needs to be properly addressed in libxl toolstack.

Odd. I thought you could. The only one missing was the PV framebuffer + intial domain support but the rest were enabled. And that initial domain support was due to them mucking with Kconfig to outright disable it. > The point to be made is that Fedora is not RHEL and Centos is more like > RHEL. > > So comparing Centos to Fedora is like complaining that RHEL should > support all the current Fedora packages/features. > There is a relationship between all of them but they are not the same.
