This sentance doesn't make any sense. HVF can certainly be compared to KVM featurewise. KVM has no dependancy on / expectation of devices being impl in the Linux kernel. If using KVM, then you can optionally take advantage of other Linux features for device backends. HVF and KVM are approximately equivalent. macOS however lacks kerenl accelerated device backends. > + <ul> > + <li> > + Instruction emulation in "hvf" accelerator is not mature.

ALso if either of those options were required it would be considered a bug - we should auto-select all features We should just not document any of this, since standard build instructions should apply. > +</pre> > + > + </body> > +</html> > -- > 2.31.1 > Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
