* libxl: IDL: autogenerate functions to produce JSON from libxl data structures.Ian Campbell2011-10-071-2/+2
| | | | | | | | | | | | | | | | | | | | Two functions are provided. TYPE_gen_json exposes an interface which is compatible with the YAGL generator infrastructure. TYPE_to_string uses this to produce a pretty printed string. The TYPE_gen_json functions are defined in a new header libxl_json.h which is not exposed via libxl.h due to the use of YAGL datatypes to avoid poluting the namespace us libxl users which don't use the library themselves. If a libxl user is interested in integrating at the YAGL level then it should #include this file itself. Also update testidl to generate a random version of each IDL datastructure and convert it to JSON. Unfortunately this requires a libxl_ctx and therefore the test must be run on a Xen system now.

* tools: libxl: hide selection of device-model by default.Ian Campbell2011-04-201-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should never have been exposed to users as something they are required to think about, unless they want to. At the libxl API level: * Add libxl_device_model_info.device_model_version allowing the user to say which qemu version (e.g. old qemu-xen or qemu upstream) they want for a domain. * Add libxl_device_model_info.device_model_stubdomain allowing the user to select stub or non-stub device model * Default both the device_model field to NULL and DTRT when building a domain with that value in those fields, but still allow libxl users to specify something explicit if they want. * Note that libxl_device_model_info.device_model, if specified, must now be a complete path. At the xl level: * Support a new "device_model_version" option which sets the new libxl_device_model_info.device_model_version field. This option is mandatory if device_model_override is used. * Support a new "device_model_stubdomain_override" option which allows the user to request stubdomain if desired. * WARN if an HVM guest cfg uses the "device_model" config option, and direct users to the "device_model_override" option if they really do not want the default. If the "device_model" directive contains "stubdom-db" then direct users to the "device_model_stubdomain_override" directive. The default qemu remains the existing qemu-xen based qemu-dm and stubdomain defaults to off. I chose the name "qemu-xen traditional" to refer to the existing Xen fork of qemu and simply "qemu-xen" to refer to the new device model based on qemu upstream. I suspect that the vast majority of users only have these config options because they've copied them from somewhere and they normally have no interest in which device model is used. Renaming the fields and warning when they are used makes these decisions internal. This will allow us to make decisions at a platform level regarding the preferred hvmloader, device model, stub domain etc without requiring everyone to change their configuration files. Adding a device model version to the API is intended to make it easy for users to select what they need without having to know about the paths to specific binaries etc. Most importantly it gets rid of the parsing of the output of qemu -h... It's not clear where upstream qemu will eventually be installed, I went with /usr/bin/qemu for now.

* libxl: drop domid field from libxl_device_*Ian Campbell2011-04-081-2/+2
| | | | | | | | | | | | | | | | | | All functions which add a device to a domain already take a domid argument and the callers typically write the same value to the structure right before making the call. Functions which delete a device typically do not but adding this field makes the interface more consistent anyway and all callers have the domid to hand. All functions which return a libxl device structure are given a domid as a paramter and the caller therefore already knows which domain it is dealing with.

* libxl: disk specification interface changeKamala Narasimhan2011-02-151-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | Currently we pile all the backend and format information pertaining to disk option in a single enum. This check-in separates the two and uses two enums, one for disk format and another for disk backend. This helps clearly differentiate between disk format and backend within the implementation and also helps cleanup the code in this area in preparation for the impending parser revamping to be done post 4.1. Along with separating format and backend, this check-in also removes unwanted types and renames variables in the disk interface and fixes the code affected by the interface changes. In specific, here are the disk interface changes made - In libxl_device_disk structure physpath was renamed to pdev_path, virtpath was renamed to vdev, phystype was removed and replaced with backend and format enums. Also previously a single enum libxl_disk_phystype held the values for qcow, qcow2, vhd, aio, file, phy, empty and that got refactored into two enums, libxl_disk_format to hold unknown, qcow, qcow2, vhd, raw, empty and libxl_disk_backend to hold unknown, phy, tap and qdisk.

* libxl/xl: improve behaviour when guest fails to suspend itself.Ian Campbell2011-02-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PV suspend protocol requires guest co-operating whereby the guest must respond to a suspend request written to the xenstore control node by clearing the node and then making a suspend hypercall. Currently when a guest fails to do this libxl times out and returns a generic failure code to the caller. In response to this failure xl attempts to resume the guest. However if the guest has not responded to the suspend request then the is no guarantee that the guest has made the suspend hypercall (in fact it is quite unlikely). Since the resume process attempts to modify the return value of the hypercall (to indicate a cancelled suspend) this results in the guest eax/rax register being corrupted! To fix this change libxl to do the following: * Wait for the guest to acknowledge the suspend request. - on timeout cancel the suspend request. - if cancellation is successful then return a new error code to indicate that the guest is not responding. - if the cancel does not succeed then we raced with the guest which actually did acknowledge at the last minute, so continue. * Wait for the guest to suspend. - on timeout return the standard error code as before * Guest successfully suspended, return success. Lastly in xl do not attempt to resume a guest if it has not responded to the suspend request. Tested by live migration of PVops kernels which either ignore the suspend request, have already crashed and those which suspend/resume correctly. In the first two cases the source domain is left alone (and continues to function in the first case) and in the third the migration is successful.

* libxl, xl: fixes to domain creation cleanup logic (domid values)Ian Jackson2011-01-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libxl__domain_make makes some assumptions about the way its caller treats its uint32_t *domid parameter: specifically, if it fails it may have partially created the domain and it does not every destroy it. But it does not initialise it. Document this assumption in a comment, and assert on entry that domid not a guest domain id, to ensure that the caller has properly initialised it. Introduce a function libxl_domid_valid_guest to help with this. This is not intended to produce any practical functional change in current code. Secondly, libxl_create_stubdom calls libxl__domain_make and has no code to tear down the domain again on error. This is complicated to fix (since it may even be possible for the the domain to be left in a state where it's not possible to tell that it was going to be a stubdom for some other domain). So for now simply leave a fixme comment. Finally, in 22739:d839631b6048 we introduced "-1" as a sentinel "no such domain" value for domid. However, domid is a uint32 so testing it with "if (domid > 0)" as we do in 22740:ce208811f540 is wrong because it always triggers. Instead use libxl_domid_valid_guest. This fix means that that if "xl create" fails, it will not try to destroy the domain "-1". Previously you'd see this message: libxl: error: libxl.c:697:libxl_domain_destroy non-existant domain -1 whose "-1" many readers may have thought was an error code, but which is actually supposedly a domain id.

* tools: cpupools: Support arbitrary numbers of physical cpusJuergen Gross2010-10-211-0/+3
| | | | | | | | | | | | | | To be able to support arbitrary numbers of physical cpus it was necessary to include the size of cpumaps in the xc-interfaces for cpu pools. These were: definition of xc_cpupoolinfo_t xc_cpupool_getinfo() xc_cpupool_freeinfo() xc_cpupool_getinfo() and xc_cpupool_freeinfo() are changed to allocate the needed buffer and return it.

* xl: Implement PCI passthrough force removalGianni Tedesco2010-10-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes two errors with removing PCI devices from HVM domains. The first error is that the handling of "pci-rem" device-model command is erroneously implemented in qemu and difficult (impossible?) to get right. For example, during domain shutdown there can be a race where the guest OS unloads it's drivers and perhaps even shuts down PCI subsystem before the pci-rem command has been received by qemu. This means that no OS is present to write to the port which causes the dm command to be acknowledged. We fix this by implementing a 'force removal' option to libxl_device_pci_remove which is always set to 1 during guest shutdown. It can be optionally enabled on the xl command line for other occasions. The second error is that if a guest OS doesn't respond to the SCI interrupt and therefore the pci-rem dm command, which can happen if the guest OS has no ACPI PCI hotplug support, then device removal bails with an error but only AFTER removing the device from xenstore. This means that xenstore gets in to an inconsistent state where an assigned device also appears to be assignable. This is fixed by moving xenstore device removal to occur only after the device has really been removed.

* libxl: implementing legacy xm cpuid parserAndre Przywara2010-10-011-0/+2
| | | | | | | | | | To support compatibility with the xm config files, add a parser for the old style cpuid= syntax. This uses a Python list, so it can be distinguished from the new syntax easily.

* xl: implement parsing of cpuid parameter and translate to Xen interfaceAndre Przywara2010-10-011-0/+1
| | | | | | | | | | | | | | | | | | Parses a string enumerating cpuid flags and their behavior. The syntax is: cpuid = "host,<flagname>=[01xks],..." Supports: 0: clear this flag 1: set this flag x: don't care, use the default handling k: use the host value s: as k, but keep stable across migrations For multiple bit flags there have to be numbers passed (hex or dec), like: family=0x10,model=4 Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> committer: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
