2014-08-29block.curl: adding 'timeout' optionDaniel Henrique Barboza
The curl hardcoded timeout (5 seconds) sometimes is not long enough depending on the remote server configuration and network traffic. The user should be able to set how much long he is willing to wait for the connection. Adding a new option to set this timeout gives the user this flexibility. The previous default timeout of 5 seconds will be used if this option is not present.

2014-06-23migration: dump vmstate info as a json file for static analysisAmit Shah
This commit adds a new command, '-dump-vmstate', that takes a filename as an argument. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit. The JSON-format output can then be used to compare the vmstate info for different QEMU versions, specifically to test whether live migration would break due to changes in the vmstate data. A Python script that compares the output of such JSON dumps is included in the following commit.

Other options (nowait, telnet) will make the chardev unusable and the netdev will not be initialised.

2013-12-09net: Adding netmap network backendVincenzo Maffione
This patch adds support for a network backend based on netmap. netmap is a framework for high speed packet I/O. You can use it to build extremely fast traffic generators, monitors, software switches or network middleboxes. Its companion software switch VALE lets you interconnect virtual machines. netmap and VALE are implemented as a non-intrusive kernel module, support NICs from multiple vendors, are part of standard FreeBSD distributions and available in source format for Linux too. To compile QEMU with netmap support, use the following configure options: ./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys where "/path/to/netmap" contains the netmap source code, available at http://info.iet.unipi.it/~luigi/netmap/ The same webpage contains more information about the netmap project (together with papers and presentations).

2013-07-29Revert "chardev: Make the name of memory device consistent"Markus Armbruster
This reverts commit 6a85e60cb994bd95d1537aafbff65816f3de4637. Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver" introduced a memory ring buffer character device driver named "memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff & doc fixes" changed the driver name to "ringbuf", along with a whole bunch of other names, with the following rationale: Naming is a mess. The code calls the device driver CirMemCharDriver, the public API calls it "memory", "memchardev", or "memchar", and the special commands are named like "memchar-FOO". "memory" is a particularly unfortunate choice, because there's another character device driver called MemoryDriver. Moreover, the device's distinctive property is that it's a ring buffer, not that's in memory. This is what we released in 1.4.0. Unfortunately, the rename missed a critical instance of "memory": the actual driver name. Thus, the new device could be used only by an entirely undocumented name. The documented name did not work. Bummer. Commit 6a85e60 fixes this by changing the documentation to match the code. It also changes some, but not all related occurences of "ringbuf" to "memory". Left alone are identifiers in C code, HMP and QMP commands. The latter are external interface, so they can't be changed. The result is an inconsistent mess. Moreover, "memory" is a rotten name. The device's distinctive property is that it's a ring buffer, not that's in memory. User's don't care whether it's in RAM, flash, or carved into chocolate tablets by Oompa Loompas. Revert the commit. Next commit will fix just the bug.

Added TLS support to the VNC QEMU Websockets implementation. VNC-TLS needs to be enabled for this feature to be used. The required certificates are specified as in case of VNC-TLS with the VNC parameter "x509=<path>". If the server certificate isn't signed by a rooth authority it needs to be manually imported in the browser because at least in case of Firefox and Chrome there is no user dialog, the connection just gets canceled. As a side note VEncrypt over Websocket doesn't work atm because TLS can't be stacked in the current implementation. (It also didn't work before) Nevertheless to my knowledge there is no HTML 5 VNC client which supports it and the Websocket connection can be encrypted with regular TLS now so it should be fine for most use cases.

2013-04-22Add option to mlock qemu and guest memorySatoru Moriya
In certain scenario, latency induced by paging is significant and memory locking is needed. Also, in the scenario with untrusted guests, latency improvement due to mlock is desired. This patch introduces a following new option to mlock guest and qemu memory: -realtime mlock=on|off Signed-off-by: Satoru Moriya <satoru.moriya@hds.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 1366382526-26146-1-git-send-email-pbonzini@redhat.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.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.
