2012-01-04hw/9pfs: Add new proxy filesystem driverM. Mohan Kumar
Add new proxy filesystem driver to add root privilege to qemu process. It needs a helper process to be started by root user. Following command line can be used to utilize proxy filesystem driver -virtfs proxy,id=<id>,mount_tag=<tag>,socket_fd=<socket-fd> Signed-off-by: M.

2012-01-04hw/9pfs: Move pdu_marshal/unmarshal code to a seperate fileM. Mohan Kumar

2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-22sheepdog: move coroutine send/recv function to generic codePaolo Bonzini
Outside coroutines, avoid busy waiting on EAGAIN by temporarily making the socket blocking. The API of qemu_recvv/qemu_sendv is slightly different from do_readv/do_writev because they do not handle coroutines. It returns the number of bytes written before encountering an EAGAIN. The specificity of yielding on EAGAIN is entirely in qemu-coroutine.c. Reviewed-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

handle fs driver require a set of newly added syscalls. Don't Compile handle FS driver if those syscalls are not available. Instead of adding #ifdef for all those syscalls we check for open by handle syscall. If that is available then rest of the syscalls used by the driver should be available.

2011-10-31hw/9pfs: Add synthetic file system support using 9pAneesh Kumar K.V
This patch create a synthetic file system with mount tag v_synth when -virtfs_synth command line option is specified in qemu. The synthetic file system can be mounted in guest using 9p using the below command line mount -t 9p -oversion=9p2000.L,trans=virtio v_synth <mountpint> Synthetic file system enabled different qemu subsystem to register callbacks for read and write events from guest. The subsystem can create directories and files in the synthetic file system as show in ex below qemu_v9fs_synth_mkdir(NULL, 0777, "test2", &node); qemu_v9fs_synth_add_file(node, 0777, "testfile", my_test_read, NULL, NULL); Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
2011-10-28iSCSI block driverRonnie Sahlberg
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-08-21guest agent: remove uneeded dependenciesMichael Roth
This patch tries to cull any uneeded library dependencies from the guest agent to improve portability across various distros. We do so by being as explicit as possible about in-tree dependencies rather than relying on existing *-obj-y targets, and by manually setting LIBS for the qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by configure.

2011-08-04usb: use iovecs in USBPacketGerd Hoffmann
Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
