* tools: use system installed libaio by default.Ian Campbell2011-11-221-2/+6
| | | | | | | | | | | | | | | | | | | | I could have sworn I did this years ago. IIRC the need for our own copy was due to the use of io_set_eventfd which is not present in version 0.3.106. However it is in 0.3.107 the first version of which was uploaded to Debian in June 2008 (I can't find a better reference for the release date). The necessary version is available in Debian Lenny onwards and is in at least RHEL 6, Fedora 13 and OpenSuSE 11.3. The necessary version appears to not be available in RHEL 5 or SLES 11 which is why I haven't simply nuked the in tree version. This is based on tools-system-libaio.diff from the Debian packaging although I have made it optional (but default on).

* libvchan: interdomain communications libraryDaniel De Graaf2011-10-061-0/+1
| | | | | | | | | | | | | | | | | | | | | This library implements a bidirectional communication interface between applications in different domains, similar to unix sockets. Data can be sent using the byte-oriented libvchan_read/libvchan_write or the packet-oriented libvchan_recv/libvchan_send. Channel setup is done using a client-server model; domain IDs and a port number must be negotiated prior to initialization. The server allocates memory for the shared pages and determines the sizes of the communication rings (which may span multiple pages, although the default places rings and control within a single page). With properly sized rings, testing has shown that this interface provides speed comparable to pipes within a single Linux domain; it is significantly faster than network-based communication.

* tools: Revert seabios and upstream qemu build changesIan Jackson2011-09-141-25/+39
| | | | | | | | | | | | | | | These have broken the build and it seems to be difficult to fix. So we will revert the whole lot for now, and await corrected patch(es). Revert "fix the build when CONFIG_QEMU is specified by the user" Revert "tools: fix permissions of git-checkout.sh" Revert "scripts/git-checkout.sh: Is not bash specific. Invoke with /bin/sh."

* tools: remove fs-front/fs-backTim Deegan2011-01-111-2/+0
| | | | | | | | | | | | | | | | Its access controls are really not OK. In particular, it's not good for libxl, which stores per-VM config blobs in a directory that is exported to all VMs. This will break stub-qemu save/restore, which is the only user of fs-front that I'm aware of, but: - It's currently broken anyway (fs-back isn't run by default and crashes if it is run manually); and - Stefano has a plan to plumb qemu save records through a dedicated console channel instead.

* qemu-xen: build adjustments to support out-of-tree buildsJan Beulich2010-11-231-11/+6
| | | | | | | | | | | | | | | | QEMU by itself can be built outside of its source directory. With the qemu repository being separate from the hypervisor/tools one it seems to make sense to make use of this feature, but doing so requires a couple of adjustments to the Xen changes to it. Basically, if CONFIG_QEMU is found to indicate an existing directory, this directory will be used rather than cloning the git repo into the build tree. [ This changeset is the xen-unstable part of the patch but also includes the QEMU_TAG update to pull in the qemu part. -iwj ] Signed-off-by: Jan Beulich <jbeulich@novell.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

| | | | | | | | | | | | | This patch adds an explicit update mechanism: make tools/ioemu-dir-force-update This isn't brilliant but is better than doing "cd tools/ioemu-remote && git reset --hard <sha1...>" by hand.

* "kdd" Windows debugger stub.Tim Deegan2010-10-261-0/+11
| | | | | | | | | | | | kdd runs in dom0, attaches to a domain and speaks the Windows kd serial protocol over a TCP connection (which should go to kd or windbg, e.g. by having another VM with its virtual COM1 set up as a TCP listener). It doesn't do breakpoints &c yet, and windbg can get quite confused since the kernel debugger's not actually running, but it's good enough to extract backtraces from wedged VMs. Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com>

* Generic bi-directional map, and related initialisation functions. At the momentKeir Fraser2009-12-171-0/+2
| | | | | | | | | | | | | a single map is used to store mappings between sharing handles and disk blocks. This is used to share pages which store data read of the same blocks on (virtual) disk. Note that the map is stored in a shared memory region, as it needs to be accessed by multiple tapdisk processes. This complicates memory allocation (malloc cannot be used), prevents poniters to be stored directly (as the shared memory region might and is mapped at different base address) and finally pthread locks need to be multi-process aware.

* User-land tool for memory paging.Keir Fraser2009-12-171-0/+1
| | | | | | | | | | | | | This tool will page out the specified number of pages from the specified domain. When a paged out page is accessed, Xen will issue a request and notify the tool over an event channel. The tool will process ther request, page the page in, and notify Xen. The current (default) policy tracks the 1024 most recently paged in pages and will not choose to evict any of those. This is done with the assumption that if a page is accessed, it is likely to be accessed again soon. Signed-off-by: Patrick Colp <Patrick.Colp@citrix.com>

* tools: xenbackendd for NetBSDKeir Fraser2009-07-221-0/+1
| | | | | | | | | | | | | | | | Attached patch introduces xenbackendd. It is used on NetBSD to launch the hotplug scripts. Later xenbackendd can be improved to also launch qemu-dm as child process and will notice when qemu-dm crashes. The changes the patch makes: - rename hotplug scripts as xenbackendd expects them (current names were taken from pkgsrc) - install hotplug scripts as executable scripts - introduce xenbackendd - build/install/launch on NetBSD only Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>

* blktap2: a completely rewritten blktap implementationKeir Fraser2009-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Benefits to blktap2 over the old version of blktap: * Isolation from xenstore - Blktap devices are now created directly on the linux dom0 command line, rather than being spawned in response to XenStore events. This is handy for debugging, makes blktap generally easier to work with, and is a step toward a generic user-level block device implementation that is not Xen-specific. * Improved tapdisk infrastructure: simpler request forwarding, new request scheduler, request merging, more efficient use of AIO. * Improved tapdisk error handling and memory management. No allocations on the block data path, IO retry logic to protect guests transient block device failures. This has been tested and is known to work on weird environments such as NFS soft mounts. * Pause and snapshot of live virtual disks (see xmsnap script). * VHD support. The VHD code in this release has been rigorously tested, and represents a very mature implementation of the VHD image format. * No more duplication of mechanism with blkback. The blktap kernel module has changed dramatically from the original blktap. Blkback is now always used to talk to Xen guests, blktap just presents a Linux gendisk that blkback can export. This is done while preserving the zero-copy data path from domU to physical device. These patches deprecate the old blktap code, which can hopefully be removed from the tree completely at some point in the future.
