qemu-doc: Do not hard-code the name of the QEMU binary
In our documentation, we use a mix of "$QEMU", "qemu-system-i386" and
"qemu-system-x86_64" when we give examples to the users how to run
QEMU. Some more consistency would be good here. Also some distributions
use different names for the QEMU binary (e.g. "qemu-kvm" in RHEL), so
providing more flexibility here would also be good. Thus let's define
some variables for the names of the QEMU command and use those in the
documentation instead: @value{qemu_system} for generic examples, and
@value{qemu_system_x86} for examples that only work with the x86
binaries.

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

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

You can open an image using pre-opened file descriptors from an fd set:
|

@example
|

qemu-system-i386
|

-add-fd fd=3,set=2,opaque="rdwr:/path/to/file"

You can connect a CDROM to the slave of ide0:
|
||||
@example
|

qemu-system-i386 -drive file=file,if=ide,index=1,media=cdrom
|
||||
@value{qemu_system_x86} -drive file=file,if=ide,index=1,media=cdrom
|
||||
@end example
|
||||
|
||||
If you don't specify the "file=" argument, you define an empty drive:
|
||||
@example
|
||||
qemu-system-i386 -drive if=ide,index=1,media=cdrom
|

@value{qemu_system_x86} -drive if=ide,index=1,media=cdrom
