2013-04-15Add linux-headers to QEMU_INCLUDESJan Kiszka
virtio/dataplane/vring.c requires the Linux headers and is built for all targets. So we need to add the corresponding include to QEMU_INCLUDES to avoid that outdated distribution headers are used. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-15block: ssh: Use libssh2_sftp_fsync (if supported by libssh2) to flush to disk.Richard W.M. Jones
libssh2_sftp_fsync is an extension to libssh2 to support fsync(2) over sftp, which is itself an extension of OpenSSH. If both libssh2 and the ssh daemon support it, this will allow bdrv_flush_to_disk to commit changes through to disk on the remote server. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-04-15block: Add support for Secure Shell (ssh) block device.Richard W.M. Jones
qemu-system-x86_64 -drive file=ssh://hostname/some/image QEMU will ssh into 'hostname' and open '/some/image' which is made available as a standard block device. You can specify a username (ssh://user@host/...) and/or a port number (ssh://host:port/...). You can also use an alternate syntax using properties (file.user, file.host, file.port, file.path). Current limitations: - Authentication must be done without passwords or passphrases, using ssh-agent. Other authentication methods are not supported. - Uses a single connection, instead of concurrent AIO with multiple SSH connections. This is implemented using libssh2 on the client side. The server just requires a regular ssh daemon with sftp-server support. Most ssh daemons on Unix/Linux systems will work out of the box. Signed-off-by: Richard W.M.

2013-04-12cpu-exec: Allow "-d exec" in non-debug builds (drop CONFIG_DEBUG_EXEC)Peter Maydell
The CONFIG_DEBUG_EXEC define compiles out a single qemu_log_mask() call, which is a pretty trivial cost even for something in the main cpu_exec() loop. Having this be conditionally defined means that '-d exec' on a non-debug build will silently do nothing. Drop the define and the configure machinery that sets it, in favour of just always allowing this log option to be enabled at runtime. As a concession to the mainloopiness, we use qemu_loglevel_mask()+qemu_log() rather than qemu_log_mask() to avoid the function call overhead. Note that DEBUG_DISAS is always defined, so removing the '|| defined(CONFIG_DEBUG_EXEC)' from those conditionals makes no behavioural change for that logging.

2013-04-08configure: Don't fall back to gthread coroutine backendPeter Maydell
The gthread coroutine backend is broken and does not produce a working QEMU; it is only useful for some very limited debugging situations. Clean up the backend selection logic in configure so that it now runs "if on windows use windows; else prefer ucontext; else sigaltstack". To do this we refactor the configure code to separate out "test whether we have a working ucontext", "pick a default if user didn't specify" and "validate that user didn't specify something invalid", rather than having all three of these run together. We also simplify the Makefile logic so it just links in the backend the configure script selects.

2013-02-21ui: add basic GTK gui (v5)Anthony Liguori
This is minimalistic and just contains the basic widget infrastructure. The GUI consists of a menu and a GtkNotebook. To start with, the notebook has its tabs hidden which provides a UI that looks very similar to SDL with the exception of the menu bar. The menu bar allows a user to toggle the visibility of the tabs. Cairo is used for rendering. I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU since it was originally written as a remote display for QEMU. So for the most part, the approach to rendering and keyboard handling should be pretty solid for GTK.

2013-01-21vnc: added initial websocket protocol supportTim Hardeck
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support to QEMU VNC. Binary encoding support on the client side is mandatory. Because of the GnuTLS requirement the Websockets implementation is optional (--enable-vnc-ws). To activate Websocket support the VNC option "websocket"is used, for example "-vnc :0,websocket". The listen port for Websocket connections is (5700 + display) so if QEMU VNC is started with :0 the Websocket port would be 5700. As an alternative the Websocket port could be manually specified by using ",websocket=<port>" instead. Parts of the implementation base on Anthony Liguori's QEMU Websocket patch from 2010 and on Joel Martin's LibVNC Websocket implementation.
