QEMU added -drive in 2007, and NBD in 2008. Both appeared first in
release 0.10.0. Thus the code to support network disks without -drive
is dead, and in fact it incorrectly escapes commas. Drop it.
The network disks support appeared in 0.8.7: Jan 4 2011 actually.

add network disk support
This patch adds network disk support to libvirt/QEMU. The currently
supported protocols are nbd, rbd, and sheepdog. The XML syntax is like
this:
<disk type="network" device="disk">
<driver name="qemu" type="raw" />
<source protocol='rbd|sheepdog|nbd' name="...some image
identifier...">
<host name="mon1.example.org" port="6000">
<host name="mon2.example.org" port="6000">
<host name="mon3.example.org" port="6000">
</source>
<target dev="vda" bus="virtio" />
</disk>

I believe -drive support is before 0.8.7, but how about libvirt is new
enough with the network disk support, and qemu too old without -drive
support?
