2008-11-11sockets: helper functions for qemu (Gerd Hoffman)aliguori
This patch creates a new source file qemu-sockets.c with a bunch of helper functions to create listening and connected sockets. New features of this code are (a) support for searching for a free port in a given range and (b) support for IPv6. The following patches put that code into use.

2008-11-11Reintroduce migrate-to-exec: support (Charles Duffy)aliguori
KVM's live migration support included support for exec: URLs, allowing system state to be written or received via an arbitrary popen()ed subprocess. This provides a convenient way to pipe state through a compression algorithm or an arbitrary network transport on its way to its destination, and a convenient way to write state to disk; libvirt's qemu driver currently uses migration to exec: targets for this latter purpose. This version of the patch refactors now-common code from migrate-tcp.c into migrate.c.

2008-11-05Add KVM support to QEMUaliguori
This patch adds very basic KVM support. KVM is a kernel module for Linux that allows userspace programs to make use of hardware virtualization support. It current supports x86 hardware virtualization using Intel VT-x or AMD-V. It also supports IA64 VT-i, PPC 440, and S390. This patch only implements the bare minimum support to get a guest booting. It has very little impact the rest of QEMU and attempts to integrate nicely with the rest of QEMU. Even though this implementation is basic, it is significantly faster than TCG. Booting and shutting down a Linux guest: w/TCG: 1:32.36 elapsed 84% CPU w/KVM: 0:31.14 elapsed 59% CPU Right now, KVM is disabled by default and must be explicitly enabled with -enable-kvm. We can enable it by default later when we have had better testing.

2008-10-13Introduce TCP live migration protocolaliguori
This patch introduces a tcp protocol for live migration. It can be used as follows: qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio <vm runs for a while> (qemu) migrate tcp:localhost:1025 On the same system: qemu-system-x86_64 -hda ~/images/linux-test.img -incoming tcp:localhost:1025 The monitor can be interacted with while waiting for an incoming live migration.

2008-10-13Introduce a buffered file wrapper for QEMUFilealiguori
This patch introduces a buffered QEMUFile wrapper. This allows QEMUFile's to be rate limited. It also makes it easier to implement a QEMUFile that is asynchronous since the current QEMUFile API requires that all reads and writes be synchronous. The only real non-obvious part of the API is the "frozen" concept. If the backend returns EAGAIN, the QEMUFile is said to be "frozen". This means no additional output will be sent to the backend until the file is unfrozen. qemu_file_put_notify can be used to unfreeze a frozen file. A synchronous interface is also provided to wait for an unfreeze event. This is used during the final part of live migration when the VM is no longer running.

2008-10-08Fix IO performance regression in sparcaliguori
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.

2008-09-22Refactor AIO to allow multiple AIO implementationsaliguori
This patch refactors the AIO layer to allow multiple AIO implementations. It's only possible because of the recent signalfd() patch. Right now, the AIO infrastructure is pretty specific to the block raw backend. For other block devices to implement AIO, the qemu_aio_wait function must support registration. This patch introduces a new function, qemu_aio_set_fd_handler, which can be used to register a file descriptor to be called back. qemu_aio_wait() now polls a set of file descriptors registered with this function until one becomes readable or writable. This patch should allow the implementation of alternative AIO backends (via a thread pool or linux-aio) and AIO backends in non-traditional block devices (like NBD).

2008-09-11Only build compatfd when using AIO and make sure to always init AIOaliguori
OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO. Also make sure to call qemu_aio_init() from bdrv_init. Everything that uses bdrv calls bdrv_init so it makes sense to init aio from there instead of in every single tool.

2008-09-10Use signalfd() to work around signal/select racealiguori
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.
