With I<--pretty>, cpu affinities are shown as ranges.
An example output is

B<STATES>
The State field displays the current operating state of a virtual CPU
=over 4
=item B<offline>
The virtual CPU is offline and not usable by the domain.
This state is not supported by all hypervisors.
=item B<running>
The virtual CPU is available to the domain and is operating.
=item B<blocked>
The virtual CPU is available to the domain but is waiting for a resource.
This state is not supported by all hypervisors, in which case I<running>
may be reported instead.
=item B<no state>
The virtual CPU state could not be determined. This could happen if
the hypervisor is newer than virsh.
=item B<N/A>
There's no information about the virtual CPU state available. This can
be the case if the domain is not running or the hypervisor does
not report the virtual CPU state.
