This patch fixes migration so that it works on Win32. This requires using socket specific calls since sockets cannot be treated like file descriptors on win32.

The live migration code broke the windows build. As part of this change, I've switched the BIOS path to C:\Program Files\Qemu instead of /c/Program Files/Qemu. The later is only valid when launching from MSYS but the former is always valid.

This patch changes the cache= option to accept none, writeback, or writethough to control the host page cache behavior. By default, writethrough caching is now used which internally is implemented by using O_DSYNC to open the disk images. When using -snapshot, writeback is used by default since data integrity it not at all an issue. cache=none has the same behavior as cache=off previously. The later syntax is still supported by now deprecated. I also cleaned up the O_DIRECT implementation to avoid many of the #ifdefs.

This patch allows QEMUFile's read and write operations to return negative error codes. This is necessary to detect things like closed streams during live migration. It also removes unused code for QEMUFileFD write path. Finally, it makes sure to avoid attempting to flush an output buffer if the file is only being used for input. This was spotted by Uri Lublin.

Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.

Introduce a max_cpus per-machine variable, allowing individual boards to limit it's number of CPUs.

This patch replaces the static memory savevm/loadvm handler with a "live" one. This handler is used even if performing a non-live migration. The key difference between this handler and the previous is that each page is prefixed with the address of the page. The QEMUFile rate limiting code, in combination with the live migration dirty tracking bits, is used to determine which pages should be sent and how many should be sent. The live save code "converges" when the number of dirty pages reaches a fixed amount. Currently, this is 10 pages. This is something that should eventually be derived from whatever the bandwidth limitation is.

The current savevm/loadvm protocol has some draw backs. It does not support the ability to do progressive saving which means it cannot be used for live checkpointing or migration. The sections sizes are 32-bit integers which means that it will not function when using more than 4GB of memory for a guest. It attempts to seek within the output file which means it cannot be streamed. The current protocol also is pretty lax about how it supports forward compatibility. If a saved section version is greater than what the restore code support, the restore code generally treats the saved data as being in whatever version it supports. This means that restoring a saved VM on an older version of QEMU will likely result in silent guest failure. This patch introduces a new version of the savevm protocol. It has the following features: * Support for progressive save of sections (for live checkpoint/migration) * An asynchronous API for doing save * Support for interleaving multiple progressive save sections (for future support of memory hot-add/storage migration) * Fully streaming format * Strong section version checking Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5434 c046a42c-6fe2-441c-8c8c-71466251a162

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.

This patch adds support for removing USB devices by host address. Which is usefull for things like libvirtd because there is no easy way to find guest USB address of the host device. In other words you can now do: usb_add host:3.5 ... usb_del host:3.5 Before the patch 'usb_del' did not support 'host:' notation. ---- Syntax for specifying auto connect filters has been improved. Old syntax was host:bus.dev host:pid:vid New syntax is host:auto:bus.dev[:pid:vid] In both the cases any attribute can be set to "*". New syntax is more flexible and lets you do things like host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */ It's now possible to remove auto filters. For example: usb_del host:auto:3.*:5533:* Active filters are printed after all host devices in 'info usb' output. Which now looks like this: Device 1.1, speed 480 Mb/s Hub: USB device 1d6b:0002, EHCI Host Controller Device 1.4, speed 480 Mb/s Class 00: USB device 1058:0704, External HDD Auto filters: Device 3.* ID *:* Signed-off-by: NMax Krasnyansky <maxk@kernel.org> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5205 c046a42c-6fe2-441c-8c8c-71466251a162

This patch introduces signalfd() to work around the signal/select race in checking for AIO completions. For platforms that don't support signalfd(), we emulate it with threads. There was a long discussion about this approach. I don't believe there are any fundamental problems with this approach and I believe eliminating the use of signals is a good thing. I've tested Windows and Linux using Windows and Linux guests. I've also checked for disk IO performance regressions.
