set_hv

set the hypervisor binary

Set the hypervisor binary that we will use. The hypervisor depends on the backend, but is usually the location of the qemu/KVM hypervisor. For the uml backend, it is the location of the linux or vmlinux binary.

The default is chosen when the library was compiled by the configure script.

You can also override this by setting the LIBGUESTFS_HV environment variable.

Note that you should call this function as early as possible after creating the handle. This is because some pre-launch operations depend on testing qemu features (by running "qemu -help"). If the qemu binary changes, we don't retest features, and so you might see inconsistent results. Using the environment variable LIBGUESTFS_HV is safest of all since that picks the qemu binary at the same time as the handle is created.

Parameters:

this	A GuestfsSession object

Returns:

true on success, false on error
