/* Test storage pool implementation
*
* These functions aid testing of storage pool related stuff when creating a
* qemu command line.
*
* There are a few "magic" values to pass to these functions:
*
* 1) "inactive" as a pool name to create an inactive pool. All other names are
* interpreted as file names in storagepoolxml2xmlout/ and are used as the
* definition for the pool. If the file doesn't exist the pool doesn't exist.
*
* 2) "nonexistent" returns an error while looking up a volume. Otherwise
* pattern VOLUME_TYPE+VOLUME_PATH can be used to simulate a volume in a pool.
* This creates a fake path for this volume. If the '+' sign is omitted, block
* type is assumed.

Introduce new OOM testing support The previous OOM testing support would re-run the entire "main" method each iteration, failing a different malloc each time. When a test suite has 'n' allocations, the number of repeats requires is (n * (n + 1) ) / 2. This gets very large, very quickly. This new OOM testing support instead integrates at the virtTestRun level, so each individual test case gets repeated, instead of the entire test suite. This means the values of 'n' are orders of magnitude smaller. The simple usage is $ VIR_TEST_OOM=1 ./qemuxml2argvtest ... 29) QEMU XML-2-ARGV clock-utc ... OK Test OOM for nalloc=36 .................................... OK 30) QEMU XML-2-ARGV clock-localtime ... OK Test OOM for nalloc=36 .................................... OK 31) QEMU XML-2-ARGV clock-france ... OK Test OOM for nalloc=38 ...................................... OK ... the second lines reports how many mallocs have to be failed, and thus how many repeats of the test will be run. If it crashes, then running under valgrind will often show the problem $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When debugging problems it is also helpful to select an individual test case $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When things get really tricky, it is possible to request that just specific allocs are failed. eg to fail allocs 5 -> 12, use $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest In the worse case, you might want to know the stack trace of the alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it is set to 1 then it will only print if it thinks a mistake happened. This is often not reliable, so setting it to 2 will make it print the stack trace for every alloc that is failed. $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest 30) QEMU XML-2-ARGV clock-localtime ...

tests: simplify common setup A few of the tests were missing basic sanity checks, while most of them were doing copy-and-paste initialization (in fact, some of them pasted the argc > 1 check more than once!). It's much nicer to do things in one common place, and minimizes the size of the next patch that fixes getcwd usage. * tests/testutils.h (EXIT_AM_HARDFAIL): New define.

tests: guarantee abs_srcdir in all C tests While trying to debug a failure of virpcitest during 'make distcheck', I noticed that with a VPATH build, 'cd tests; ./virpcitest' fails for an entirely different reason. To reproduce the distcheck failure, I had to run 'cd tests; abs_srcdir=/path/to/src ./virpcitest'. But we document in HACKING that all of our tests are supposed to be runnable without requiring extra environment variables. The solution: hardcode the location of srcdir into the just-built binaries, rather than requiring make to prepopulate environment variables. With this, './virpcitest' passes even in a VPATH build (provided that $(srcdir) is writable; a followup patch will fix the conditions required by 'make distcheck'). [Note: the makefile must still pass on directory variables to the test environment of shell scripts, since those aren't compiled. So while this solves the case of a compiled test, it still requires environment variables to pass a VPATH build of any shell script test case that relies on srcdir.] * tests/Makefile.am (AM_CFLAGS): Define abs_srcdir in all compiled tests. * tests/testutils.h (abs_srcdir): Quit declaring. * tests/testutils.c (virtTestMain): Rely on define rather than environment variable. * tests/virpcimock.c (pci_device_new_from_stub): Rely on define. * tests/cputest.c (mymain): Adjust abs_top_srcdir default. * tests/qemuxml2argvtest.c (mymain): Likewise. * tests/qemuxmlnstest.c (mymain): Likewise.

qemu: add new disk device='lun' for bus='virtio' & type='block' In the past, generic SCSI commands issued from a guest to a virtio disk were always passed through to the underlying disk by qemu, and the kernel would also pass them on. As a result of CVE-2011-4127 (see: http://seclists.org/oss-sec/2011/q4/536), qemu now honors its scsi=on|off device option for virtio-blk-pci (which enables/disables passthrough of generic SCSI commands), and the kernel will only allow the commands for physical devices (not for partitions or logical volumes). The default behavior of qemu is still to allow sending generic SCSI commands to physical disks that are presented to a guest as virtio-blk-pci devices, but libvirt prefers to disable those commands in the standard virtio block devices, enabling it only when specifically requested (hopefully indicating that the requester understands what they're asking for). For this purpose, a new libvirt disk device type (device='lun') has been created. device='lun' is identical to the default device='disk', except that: 1) It is only allowed if bus='virtio', type='block', and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if device !='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are specifically forbidden). Guests which continue to use disk device='disk' (the default) will no longer be able to use SG_IO commands on the disk; those that have their disk device changed to device='lun' will still be able to use SG_IO commands. *docs/formatdomain.html.in - document the new device attribute value. *docs/schemas/domaincommon.rng - allow it in the RNG *tests/* - update the args of several existing tests to add scsi=off, and add one new test that will test scsi=on. *src/conf/domain_conf.c - update domain XML parser and formatter *src/qemu/qemu_(command|driver|hotplug).c - treat VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above. Note that no support for this new device value was added to any hypervisor drivers other than qemu, because it's unclear what it might mean (if anything) to those drivers.

qemu: add new disk device='lun' for bus='virtio' & type='block' In the past, generic SCSI commands issued from a guest to a virtio disk were always passed through to the underlying disk by qemu, and the kernel would also pass them on. As a result of CVE-2011-4127 (see: http://seclists.org/oss-sec/2011/q4/536), qemu now honors its scsi=on|off device option for virtio-blk-pci (which enables/disables passthrough of generic SCSI commands), and the kernel will only allow the commands for physical devices (not for partitions or logical volumes). The default behavior of qemu is still to allow sending generic SCSI commands to physical disks that are presented to a guest as virtio-blk-pci devices, but libvirt prefers to disable those commands in the standard virtio block devices, enabling it only when specifically requested (hopefully indicating that the requester understands what they're asking for). For this purpose, a new libvirt disk device type (device='lun') has been created. device='lun' is identical to the default device='disk', except that: 1) It is only allowed if bus='virtio', type='block', and the qemu version is "new enough" to support it ("new enough" == qemu 0.11 or better), otherwise the domain will fail to start and a CONFIG_UNSUPPORTED error will be logged). 2) The option "scsi=on" will be added to the -device arg to allow SG_IO commands (if device !='lun', "scsi=off" will be added to the -device arg so that SG_IO commands are specifically forbidden). Guests which continue to use disk device='disk' (the default) will no longer be able to use SG_IO commands on the disk; those that have their disk device changed to device='lun' will still be able to use SG_IO commands. *docs/formatdomain.html.in - document the new device attribute value. *docs/schemas/domaincommon.rng - allow it in the RNG *tests/* - update the args of several existing tests to add scsi=off, and add one new test that will test scsi=on. *src/conf/domain_conf.c - update domain XML parser and formatter *src/qemu/qemu_(command|driver|hotplug).c - treat VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above. Note that no support for this new device value was added to any hypervisor drivers other than qemu, because it's unclear what it might mean (if anything) to those drivers.

qemu: support event_idx parameter for virtio disk and net devices In some versions of qemu, both virtio-blk-pci and virtio-net-pci devices can have an event_idx setting that determines some details of event processing. When it is enabled, it "reduces the number of interrupts and exits for the guest". qemu will automatically enable this feature when it is available, but there may be cases where this new feature could actually make performance worse (NB: no such case has been found so far). As a safety switch in case such a situation is encountered in the field, this patch adds a new attribute "event_idx" to the <driver> element of both disk and interface devices. event_idx can be set to "on" (to force event_idx on in case qemu has it disabled by default) or "off" (for force event_idx off). In the case that event_idx support isn't present in qemu, the attribute is ignored (this on the advice of the qemu developer). docs/formatdomain.html.in: document the new flag (marking it as "don't mess with this!" docs/schemas/domain.rng: add event_idx in appropriate places src/conf/domain_conf.[ch]: add event_idx to parser and formatter src/libvirt_private.syms: export virDomainVirtioEventIdx(From|To)String src/qemu/qemu_capabilities.[ch]: detect and report event_idx in disk/net src/qemu/qemu_command.c: add event_idx parameter to qemu commandline when appropriate. tests/qemuxml2argvdata/qemuxml2argv-event_idx.args, tests/qemuxml2argvdata/qemuxml2argv-event_idx.xml, tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c: test cases for event_idx.

"-global" is the only way to define vram_size for the primary qxl device, regardless of how qemu names it, (It's not good a good way, as original idea of "-global" is to set a global default for a driver property, but to specify vram for first qxl device, we have to use it). For other qxl devices, as they are represented by "-device", could specify it directly and seperately for each, and it overrides the default set by "-global" if specified. v1 - v2: * modify "virDomainVideoDefaultRAM" so that it returns 16M as the default vram_size for qxl device. * vram_size * 1024 (qemu accepts bytes for vram_size). * apply default vram_size for qxl device for which vram_size is not specified. * modify "graphics-spice" tests (more sensiable vram_size) * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr, to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr). v2 - v3: * Modify default video memory size for qxl device from 16M to 24M * Update codes to be consistent with changes on qemu_capabilities.*

qemu: support type='hostdev' network devices at domain start This patch makes sure that each network device ("interface") of type='hostdev' appears on both the hostdevs list and the nets list of the virDomainDef, and it modifies the qemu driver startup code so that these devices will be presented to qemu on the commandline as hostdevs rather than as network devices. It does not add support for hotplug of these type of devices, or code to honor the <mac address> or <virtualport> given in the config (both of those will be done in separate patches). Once each device is placed on both lists, much of what this patch does is modify places in the code that traverse all the device lists so that these hybrid devices are only acted on once - either along with the other hostdevs, or along with the other network interfaces. (In many cases, only one of the lists is traversed / a specific operation is performed on only one type of device. In those instances, the code can remain unchanged.) There is one special case - when building the commandline, interfaces are allowed to proceed all the way through networkAllocateActualDevice() before deciding to skip the rest of netdev-specific processing - this is so that (once we have support for networks with pools of hostdev devices) we can get the actual device allocated, then rely on the loop processing all hostdevs to generate the correct commandline. (NB: <interface type='hostdev'> is only supported for PCI network devices that are SR-IOV Virtual Functions (VF). Standard PCI[e] and USB devices, and even the Physical Functions (PF) of SR-IOV devices can only be assigned to a guest using the more basic <hostdev> device entry. This limitation is mostly due to the fact that non-SR-IOV ethernet devices tend to lose mac address configuration whenever the card is reset, which happens when a card is assigned to a guest; SR-IOV VFs fortunately don't suffer the same problem.)

selinux: distinguish failure to label from request to avoid label https://bugzilla.redhat.com/show_bug.cgi?id=924153 Commit 904e05a2 (v0.9.9) added a per-<disk> seclabel element with an attribute relabel='no' in order to try and minimize the impact of shutdown delays when an NFS server disappears. The idea was that if a disk is on NFS and can't be labeled in the first place, there is no need to attempt the (no-op) relabel on domain shutdown. Unfortunately, the way this was implemented was by modifying the domain XML so that the optimization would survive libvirtd restart, but in a way that is indistinguishable from an explicit user setting. Furthermore, once the setting is turned on, libvirt avoids attempts at labeling, even for operations like snapshot or blockcopy where the chain is being extended or pivoted onto non-NFS, where SELinux labeling is once again possible. As a result, it was impossible to do a blockcopy to pivot from an NFS image file onto a local file. The solution is to separate the semantics of a chain that must not be labeled (which the user can set even on persistent domains) vs. the optimization of not attempting a relabel on cleanup (a live-only annotation), and using only the user's explicit notation rather than the optimization as the decision on whether to skip a label attempt in the first place. When upgrading an older libvirtd to a newer, an NFS volume will still attempt the relabel; but as the avoidance of a relabel was only an optimization, this shouldn't cause any problems. In the ideal future, libvirt will eventually have XML describing EVERY file in the backing chain, with each file having a separate <seclabel> element. At that point, libvirt will be able to track more closely which files need a relabel attempt at shutdown. But until we reach that point, the single <seclabel> for the entire <disk> chain is treated as a hint - when a chain has only one file, then we know it is accurate; but if the chain has more than one file, we have to attempt relabel in spite of the attribute, in case part of the chain is local and SELinux mattered for that portion of the chain. * src/conf/domain_conf.h (_virSecurityDeviceLabelDef): Add new member. * src/conf/domain_conf.c (virSecurityDeviceLabelDefParseXML): Parse it, for live images only.

qemu: set/validate slot/connection type when assigning slots for PCI devices Since PCI bridges, PCIe bridges, PCIe switches, and PCIe root ports all share the same namespace, they are all defined as controllers of type='pci' in libvirt (but with a differing model attribute). Each of these controllers has a certain connection type upstream, allows certain connection types downstream, and each can either allow a single downstream connection at slot 0, or connections from slot 1 - 31. Right now, we only support the pci-root and pci-bridge devices, both of which only allow PCI devices to connect, and both which have usable slots 1 - 31. In preparation for adding other types of controllers that have different capabilities, this patch 1) adds info to the qemuDomainPCIAddressBus object to indicate the capabilities, 2) sets those capabilities appropriately for pci-root and pci-bridge devices, and 3) validates that the controller being connected to is the proper type when allocating slots or validating that a user-selected slot is appropriate for a device.. Having this infrastructure in place will make it much easier to add support for the other PCI controller types. While it would be possible to do all the necessary checking by just storing the controller model in the qemyuDomainPCIAddressBus, it greatly simplifies all the validation code to also keep a "flags", "minSlot" and "maxSlot" for each - that way we can just check those attributes rather than requiring a nearly identical switch statement everywhere we need to validate compatibility. You may notice many places where the flags are seemingly hard-coded to QEMU_PCI_CONNECT_HOTPLUGGABLE | QEMU_PCI_CONNECT_TYPE_PCI This is currently the correct value for all PCI devices, and in the future will be the default, with small bits of code added to change to the flags for the few devices which are the exceptions to this rule. Finally, there are a few places with "FIXME" comments. Note that these aren't indicating places that are broken according to the currently supported devices, they are places that will need fixing when support for new PCI controller models is added. To assure that there was no regression in the auto-allocation of PCI addresses or auto-creation of integrated pci-root, ide, and usb controllers, a new test case (pci-bridge-many-disks) has been added to both the qemuxml2argv and qemuxml2xml tests. This new test defines a domain with several dozen virtio disks but no pci-root or pci-bridges. The .args file of the new test case was created using libvirt sources from before this patch, and the test still passes after this patch has been applied.

qemu: fix handling of default/implicit devices for q35 This patch adds in special handling for a few devices that need to be treated differently for q35 domains: usb - there is no implicit/default usb controller for the q35 machinetype. This is done because normally the default usb controller is added to a domain by just adding "-usb" to the qemu commandline, and it's assumed that this will add a single piix3 usb1 controller at slot 1 function 2. That's not what happens when the machinetype is q35, though. Instead, adding -usb to the commandline adds 3 usb (version 2) controllers to the domain at slot 0x1D.{1,2,7}. Rather than having <controller type='usb' index='0'/> translate into 3 separate devices on the PCI bus, it's cleaner to not automatically add a default usb device; one can always be added explicitly if desired. Or we may decide that on q35 machines, 3 usb controllers will be automatically added when none is given. But for this initial commit, at least we aren't locking ourselves into something we later won't want. video - qemu always initializes the primary video device immediately after any integrated devices for the machinetype. Unless instructed otherwise (by using "-device vga..." instead of "-vga" which libvirt uses in many cases to work around deficiencies and bugs in various qemu versions) qemu will always pick the first unused slot. In the case of the "pc" machinetype and its derivatives, this is always slot 2, but on q35 machinetypes, the first free slot is slot 1 (since the q35's integrated peripheral devices are placed in other slots, e.g. slot 0x1f). In order to make the PCI address of the video device predictable, that slot (1 or 2, depending on machinetype) is reserved even when no video device has been specified. sata - a q35 machine always has a sata controller implicitly added at slot 0x1F, function 2. There is no way to avoid this controller, so we always add it. Note that the xml2xml tests for the pcie-root and q35 cases were changed to use DO_TEST_DIFFERENT() so that we can check for the sata controller being automatically added. This is especially important because we can't check for it in the xml2argv output (it has no effect on that output since it's an implicit device). ide - q35 has no ide controllers. isa and smbus controllers - these two are always present in a q35 (at slot 0x1F functions 0 and 3) but we have no way of modelling them in our config. We do need to reserve those functions so that the user doesn't attempt to put anything else there though. (note that the "pc" machine type also has an ISA controller, which we also ignore).

qemu: add dmi-to-pci-bridge controller This PCI controller, named "dmi-to-pci-bridge" in the libvirt config, and implemented with qemu's "i82801b11-bridge" device, connects to a PCI Express slot (e.g. one of the slots provided by the pcie-root controller, aka "pcie.0" on the qemu commandline), and provides 31 *non-hot-pluggable* PCI (*not* PCIe) slots, numbered 1-31. Any time a machine is defined which has a pcie-root controller (i.e. any q35-based machinetype), libvirt will automatically add a dmi-to-pci-bridge controller if one doesn't exist, and also add a pci-bridge controller. The reasoning here is that any useful domain will have either an immediate (startup time) or eventual (subsequent hot-plug) need for a standard PCI slot; since the pcie-root controller only provides PCIe slots, we need to connect a dmi-to-pci-bridge controller to it in order to get a non-hot-plug PCI slot that we can then use to connect a pci-bridge - the slots provided by the pci-bridge will be both standard PCI and hot-pluggable. Since pci-bridge devices themselves can not be hot-plugged into a running system (although you can hot-plug other devices into a pci-bridge's slots), any new pci-bridge controller that is added can (and will) be plugged into the dmi-to-pci-bridge as long as it has empty slots available. This patch is also changing the qemuxml2xml-pcie test from a "DO_TEST" to a "DO_DIFFERENT_TEST". This is so that the "before" xml can omit the automatically added dmi-to-pci-bridge and pci-bridge devices, and the "after" xml can include it - this way we are testing if libvirt is properly adding these devices.
