Since qemu-kvm tree is syncronized with 4.1.0 now, it's easier to handle this as 4.1.0 and not as rc4 - Resolves: bz#1740692

If the nbd-server uses named exports (supported since NBD 2.9.18, or with QEMU's
|
|
own embedded NBD server), you must specify an export name in the URI:
|
|
@example
|

-qemu-system-i386 -cdrom nbd://localhost/debian-500-ppc-netinst

|
-qemu-system-i386 -cdrom nbd://localhost/openSUSE-11.1-ppc-netinst

|
|
also available. Here are some example of the older syntax:
