2011-05-03NBD: Avoid leaking a couple of strings when the NBD device is closedNick Thomas1-0/+4

2011-04-07NBD device: Separate out parsing configuration and opening sockets.Nick Thomas1-55/+102
We also change the way the file parameter is parsed so IPv6 IP addresses can be used, e.g.: "drive=nbd:[::1]:5000" Signed-off-by: Nick Thomas <nick@bytemark.co.uk> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-09-21nbd: correctly manage default portLaurent Vivier1-2/+0
block/nbd.c: use default port number when none is specified qemu-nbd.c: use IANA-assigned port number: 10809 Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-08-30nbd: Introduce NBD named exports.Laurent Vivier1-19/+49
This patch allows to connect Qemu using NBD protocol to an nbd-server using named exports. For instance, if on the host "isoserver", in /etc/nbd-server/config, you have: [generic] [debian-500-ppc-netinst] exportname = /ISO/debian-500-powerpc-netinst.iso [Fedora-10-ppc-netinst] exportname = /ISO/Fedora-10-ppc-netinst.iso You can connect to it, using: qemu -cdrom nbd:isoserver:exportname=debian-500-ppc-netinst qemu -cdrom nbd:isoserver:exportname=Fedora-10-ppc-netinst NOTE: you need at least nbd-server 2.9.18 Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-05-03block: Open the underlying image file in generic codeKevin Wolf1-1/+1
Format drivers shouldn't need to bother with things like file names, but rather just get an open BlockDriverState for the underlying protocol. This patch introduces this behaviour for bdrv_open implementation. For protocols which need to access the filename to open their file/device/connection/... a new callback bdrv_file_open is introduced which doesn't get an underlying file opened. For now, also some of the more obscure formats use bdrv_file_open because they open() the file themselves instead of using the block.c functions. They need to be fixed in later patches.

2010-01-26block: kill BDRV_O_CREATChristoph Hellwig1-3/+0
The BDRV_O_CREAT option is unused inside qemu and partially duplicates the bdrv_create method. Remove it, and the -C option to qemu-io which isn't used in qemu-iotests anyway. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
