[Qemu-devel] -net nic,model=? not working

[Andreas Färber]

Hello,

According to the HTML documentation, "-net nic,model=?" is supposed to  
display a list of available devices for the target. `qemu -net  
nic,model=?` however shows only the standard usage message. Anyone any  
insights why? Is the documentation wrong? The usage message itself  
does not explicitly mention '?' for that option.

The documentation is unclear.  You need to give other, valid options
for starting QEMU.  The simplest is to give the name of a disk image
file as an argument.

Then it outputs the message about NIC models and exits - after
starting then closing some devices.

Which of the drivers is the most efficient?

qemu: Supported ISA NICs: ne2k_isa
qemu: Supported PCI NICs: i82551 i82557b i82559er ne2k_pci pcnet rtl8139

ne2k_pci seems to be the default one


Seems like it doesn't work with KVM though, I use virtio with these 
machines anyways.

It depends which guest you are running, that's why there are choices.
Some guests don't support some NICs, some guests don't support others.

KVM returns a different list than the above one.

What would it be with a 32 bit Linux setup?
