Hi,
this patch allows to connect directly a disk image file to an NBD
device. It introduces the use of a unix socket (instead of inet).
- To connect a file to a device:
# qemu-nbd --connect=/dev/nbd0 my_disk.qcow2
Then you can see directly your disk (no need of nbd-client):
# fdisk -l /dev/nbd0
Disk /dev/nbd0: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/nbd0p1 * 1 492 3951958+ 83 Linux
/dev/nbd0p2 493 522 240975 5 Extended
/dev/nbd0p5 493 522 240943+ 82 Linux swap /
Solaris
- To disconnect the file from the device:
# qemu-nbd --disconnect /dev/nbd0
Regards,
Laurent
