hi,

(this is on xen-3.0.testing.hg),

I am trying to figure out what the difference is between calling
vm-assist to enable writable page tables, and what the xen-feature
with the same name does. The former is enabled, while the latter
returns false. This has the effect that the various checks from
changeset 9243:f00e257d200c fail and pages are still pinned/unpinned,
but things still seem to work. This is with my own domain builder
using libxc.

So what is the story when combining VMASST_ and XENFEAT_?

Jacob
