* xend: Add support for URI ('file:' and 'data:' scheme) for PV/kernel and ↵Keir Fraser2009-07-204-5/+300
| | | | | | | | | | | | | | | | | | | | PV/ramdisk Add support for 'file:' and 'data:' URI schemes for the parameters 'PV/kernel' and 'PV/ramdisk' in the VM.create() call. The 'data:' scheme handling enables using a file which is stored inside the management system (from where the XenAPI call is send) as kernel or ramdisk. Notes: o all included: a detailed description can be found in the xenapi documentation o bumped up the version of the API document to 1.0.8 (because of (minimal) interface extension) o Future enhancements (like http:, ftp: schemes) fit seamlessly into the current design / classes Signed-off-by: Andreas Florath <xen@flonatel.org>

* fs-back: better error handling in fs-backendKeir Fraser2009-07-084-50/+138
| | | | | | | | | | | Currently most of the error checking in fs-backend is done by the use of asserts that would terminate the daemon in case of a single error on a single request. This patch replaces the asserts with debugging messages and terminates the connection on which the error occurred. With this patch applied I was able to complete successfully over 1000 live migrations with stubdoms. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

* xend: allow pv_ops kernel driver pci-stub to hide devices for assignmentKeir Fraser2009-07-064-27/+29
| | | | | | | | | | | | | | | | | pciback is used by VT-d to hide device for assigment. But in pv-ops dom0, pciback is not supported yet. Fortunately, pci-stub module is used to hide device in Linux for KVM VT-d device assignment and it's included in pv-ops dom0. So can use pci-stub to hide devices for assignment. Device must be hidden before assignment. Control panel has checks if devices can be assigned or not, and can list assignable devices via reading devices owned by pciback. This patch changes the checks, and also list assignable devices which are owned by pci-stub. Use pci-stub to hide devices, and use this patch to pass checkes in control panel, device assignemnt with VT-d works on Xen with pv-ops dom0. Signed-off-by: Weidong Han <weidong.han@intel.com>
* blktap2: fix save/restore/migrationKeir Fraser2009-07-062-12/+36
| | | | | | | | | | | | | | | | | | | | blktap2 devices use a regular 'phy' vbd blkback backend, causing Blktap2Controller to trample the devices' parameters. This causes problems with save/restore and managed domains, among other things. This patch modifies Blktap2Controller to store both the vbd and tap2 parameters in xenstore, and stops it from trampling the device's config on device creation. * store blktap2 parameters in xenstore * restore blktap2 device config to original state once the underlying * vbd device is created (this fixes managed domains) * use blktap2 parameters rather than vbd parameters when building * blktap2 device configurations * remove blktap2 specific code from XendConfig Signed-off-by: Ryan O'Connor <rjo@cs.ubc.ca>

* blktap2: add blktap2 device class and device controllerKeir Fraser2009-07-018-87/+117
| | | | | | | | | | | | | | | | | | | blktap2 devices must be handled differently than blktap2 devices. blktap2 devices require a sysfs write to close the underlying device, as well as extra sysfs writes when the domU is paused/unpaused. The differences between blktap1 and blktap2 are great enough to warrant the creation of a new device class, 'tap2', and device controller for blktap2 devices. * add a new device controller (Blktap2Controller) and device class (tap2) for blktap2 devices * move blktap2 specific code from DevController to Blktap2Controller * if possible, check xenstore to determine block device class * use vmpath (/vm/<uuid>/) when releasing devices * modify linux hotplug cleanup script to handle blktap2 device removal Signed-off-by: Ryan O'Connor <rjo@cs.ubc.ca>

* xend: pass-through: Implement least-mapping of virtual functionsKeir Fraser2009-06-272-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternative to identity mapping virtual functions. It works by assigning the numerically lowest virtual function that is available. * The order of assignment is thus dependent on the order that physical functions are specified. e.g. config physical virtual 01.00.0,2 -> 01:00.0 -> 00:07.0 -> 01:00.2 -> 00:07.1 is different to config physical virtual 01.00.2,0 -> 01:00.2 -> 00:07.0 -> 01:00.0 -> 00:07.1 * Physical function 0 need not be present e.g. config physical virtual 01.00.1,2 -> 01:00.1 -> 00:07.0 -> 01:00.2 -> 00:07.1 * Functions from the same physical multi-function device may be exported as multiple multi-function and single-function devices e.g. 01.00.0,2 -> 01:00.0 -> 00:07.0 -> 01:00.2 -> 00:07.1 and 01.00.1,3 -> 01:00.1 -> 00:08.1 -> 01:00.3 -> 00:08.1 and 01.00.5 -> 01:00.5 -> 00:09.0 Cc: Dexuan Cui <dexuan.cui@intel.com> Cc: Masaki Kanno <kanno.masaki@jp.fujitsu.com> Signed-off-by: Simon Horman <horms@verge.net.au>

| | | | | | | | | | | When unplugging a function, all functions in the same vslot must be unplugged, and function 0 must be one of the functions present when a vslot is hot-plugged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The general format is as follows: Now: SEQ:BUS:DEV.FUNC[@VSLOT][,OPT...] New: SEQ:BUS:DEV.FUNC0-FUNCN[@VSLOT][,OPT...] SEQ:BUS:DEV.FUNC0,FUNCM,FUNCN[@VSLOT][,OPT...] SEQ:BUS:DEV.*[@VSLOT][,OPT...] In the case of unplug the VSLOT and OPT must be omitted. Xm expands this notation notation out and passes more conventional parameters to qemu-xen.

| | | | | | | | | | | | | | | | Instead of suppling a slot number to qemu-xen, supply a devfn. This and subsequent other changes will allow xend to ask for more than one function to be inserted into a single slot - by specifying which function of the slot should be used. This is a minimal patch for this change. A subsequent patch that has a lot of noise to rename slot to devfn is intended to follow.
