Simulate an SMP system with @var{n} CPUs. On the PC target, up to 255
CPUs are supported. On Sparc32 target, Linux limits the number of usable CPUs
to 4.
+For the PC target, the number of @var{cores} per socket, the number
+of @var{threads} per cores and the total number of @var{sockets} can be
+specified. Missing values will be computed. If any on the three values is
+given, the total number of CPUs @var{n} can be omitted. @var{maxcpus}
+specifies the maximum number of hotpluggable CPUs.

@item -drive @var{option}[,@var{option}[,@var{option}[,...]]]
@var{snapshot} is "on" or "off" and allows to enable snapshot for given drive (see @option{-snapshot}).
@item cache=@var{cache}
@var{cache} is "none", "writeback", or "writethrough" and controls how the host cache is used to access block data.
+@item aio=@var{aio}
+@var{aio} is "threads", or "native" and selects between pthread based disk I/O and native Linux AIO.
@item format=@var{format}
Specify which disk @var{format} will be used rather than detecting
the format. Can be used to specifiy format=raw to avoid interpreting

@item -net nic[,vlan=@var{n}][,macaddr=@var{mac}][,model=@var{type}][,name=@var{name}][,addr=@var{addr}][,vectors=@var{v}]
Create a new Network Interface Card and connect it to VLAN @var{n} (@var{n}
-= 0 is the default). The NIC is an ne2k_pci by default on the PC
+= 0 is the default). The NIC is an e1000 by default on the PC
target. Optionally, the MAC address can be changed to @var{mac}, the
device address set to @var{addr} (PCI cards only),
and a @var{name} can be assigned for use in monitor commands.
