The nova.virt.disk.vfs.guestfs Module

class VFSGuestFS(image, partition=None)

Bases: nova.virt.disk.vfs.api.VFS

This class implements a VFS module that uses the libguestfs APIs to access the disk image. The disk image is never mapped into the host filesystem, thus avoiding any potential for symlink attacks from the guest filesystem.

Prevent libguestfs trying to use KVM acceleration

It is a good idea to call this if it is known that KVM is not desired, even if technically available.
