QEMU version 2.12.1 introduced a performance feature under commit
be7773268d98 ("target-i386: add KVM_HINTS_DEDICATED performance hint").
Support for this performance hint was added in libvirt 5.7.0 by commit
cb12c59dac04 ("qemu: support for kvm-hint-dedicated performance hint").
This patch extends virt-install's existing --features option to insert the
appropriate XML into the guest definition if this feature is specified
on the command line.
E.g. --features='kvm.hint-dedicated.state=on' would result
in the following XML:
<features>
...
<kvm>
<hint-dedicated state='on'/>
</kvm>
...
</features>
