2011-04-07NBD: Use qemu_socket functions to open TCP and UNIX socketsNick Thomas
This commit has the side-effect of making the qemu-nbd binary capable of binding to IPv6 addresses. ("-b ::1", for instance). block/nbd.c fails to parse IPv6 IP addresses correctly at this point, but will work over IPv6 when given a hostname. It still works over IPv4 as before. We move the qemu-sockets object from the 'common' to the 'block' list in the Makefile. The common list includes the block list, so this is effectively a no-op for the rest of the code. We also add 32-bit 'magic' attributes to nbd_(request|reply) to facilitate calculating maximum request/response sizes later.

2010-09-21Improve qemu-nbd performance by 4400 %Laurent Vivier
This patch allows to reduce the boot time from an NBD server from 225 seconds to 5 seconds (time between the "boot cd:0" and the kernel init) for the following command lines: ./qemu-nbd -t ../ISO/debian-500-powerpc-netinst.iso and ./ppc-softmmu/qemu-system-ppc -cdrom nbd:localhost:1024 This patch combines the reply header and payload send operation.

2010-08-30nbd: Introduce NBD named exports.Laurent Vivier
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>

2008-09-15Use common objects for qemu-img and qemu-nbdaliguori
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the code. It's ugly and causes us to have to build multiple object files for linking against qemu and the tools. This patch introduces a new file, qemu-tool.c which contains enough for qemu-img, qemu-nbd, and QEMU to all share the same objects. This also required getting qemu-nbd to be a bit more Windows friendly. I also changed the Windows block-raw to use normal IO instead of overlapping IO since we don't actually do AIO yet on Windows. I changed the various #if 0's to #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows. After this patch, there are no longer any #ifdef's related to qemu-img and qemu-nbd.

2008-08-02Fix compilation of nbd on Solaris (Andreas Faerber)aliguori
Compilation of QEMU is currently broken on Solaris due to nbd's use of _IO and due to network libraries not being linked into qemu-img. The attached patch adds the appropriate libraries (copied from Makefile.target) and includes an additional Sun-specific header for _IO. With these fixes it compiles okay, on OpenSolaris snv_93 (amd64).
