Re: [Xen-users] what hypercalls are supported in user-level HVM guests?

[Big Strong <fangtuo90@xxxxxxxxx>]

Sorry I miss the list. I've enabled the privcmd driver. But what hypercalls are exposed to HVM guests? Is there a list? Looks like not all hypercalls are exposed.

If the domain has a privcmd driver then any hypercalls which are exposed to
an HVM guest is also therefore exposed to a suitably privileged HVM user
-level application.
