[libvirt] Curl/HTTP block device

[Radek Hladik]

Hi,
	I've noticed newer version of curl in last qemu changelog. It seems 
that its needed for curl block device. Unfortunatelly, I was not able to 
find out more. I tried to look into qemu source code and to some patches 
but I am not much wiser.
	As I understand it, qemu could be able to use a curl compatible URL as 
block device. Probably only in readonly mode but it still would be very 
usefull for i.e. ISO images.
	Can anyone point me in the right direction and more importantly, is 
this feature available via Libvirt?
	I checked the documentation on libvirt.org and it seems that remode 
disk can be only nbd/rbd/sheepdog.
