With current flow in qemudDomainDefine we might lose data when updating an existing domain. We parse given XML and overwrite the configuration. Then we try to save the new config. However, this step may fail and we don't perform any roll back. In fact, we remove the domain from the list of domains held up by qemu driver. This is okay as long as the domain was brand new one.

Currently, when guest agent is configured but not responsive (e.g. due to appropriate service not running in the guest) we return VIR_ERR_INTERNAL_ERROR. Both are wrong. Therefore we need to introduce new error code to reflect this case.

We were failing to react to allocation failure when initializing a snapshot object list. Changing things to store a pointer instead of a complete object adds one more possible point of allocation failure, but at the same time, will make it easier to react to failure now, as well as making it easier for a future patch to split all virDomainSnapshotPtr handling into a separate file, as I continue to add even more snapshot code.

If a domain is pmsuspended then virsh suspend will succeed. Beside obvious flaw, virsh resume will report success and change domain state to running which is another mistake. Therefore we must forbid any attempts for suspend and resume when pmsuspended.

This patch changes the behaviour of xml element cputune.period and cputune.quota to limit cpu bandwidth only for vcpus, and no longer limit cpu bandwidth for the whole guest. The reasons to do this are: - This matches docs of cputune.period and cputune.quota. - The other parts excepting vcpus are treated as "emulator", and there are separate period/quota settings for emulator in the subsequent patches

The defines QEMU_REMOTE_PORT_MIN and QEMU_REMOTE_PORT_MAX were used to find free port when starting domains. As this was hard-coded to the same ports as default VNC servers, there were races with these other programs. This patch includes the possibility to change the default starting port as well as the maximum port (mostly for completeness) in qemu config file. Support for two new config options in qemu.conf is added: - remote_port_min (defaults to QEMU_REMOTE_PORT_MIN and must be >= than this value) - remote_port_max (defaults to QEMU_REMOTE_PORT_MAX and must be <= than this value)

This patch clears these inconsistencies and makes sure the same behavior will be used when ports for remote displays are changed. Changes: - hard-coded number 5900 removed (handled elsewhere like with VNC) - reservedVNCPorts renamed to reservedRemotePorts (it's not just for VNC anymore) - QEMU_VNC_PORT_{MIN,MAX} renamed to QEMU_REMOTE_PORT_{MIN,MAX} - port allocation unified for VNC and SPICE

Setting hard_limit larger than previous swap_hard_limit must fail, it's not that good if one wants to change the swap_hard_limit and hard_limit together. E.g. % virsh memtune rhel6 hard_limit : 1000000 soft_limit : 1000000 swap_hard_limit: 1000000 % virsh memtune rhel6 --hard-limit 1000020 --soft-limit 1000020 \ --swap-hard-limit 1000020 --live This patch reorder the limits setting to set the swap_hard_limit first, hard_limit then, and soft_limit last if it's greater than current swap_hard_limit. And soft_limit first, hard_limit then, swap_hard_limit last, if not.

The parameter value for cpuset could be in special format like "0-10,^7", which is not recognized by cgroup. This patch is to ensure the cpuset is formatted as expected before passing it to cgroup. As a side effect, after the patch, it parses the cpuset early before cgroup setting, to avoid the rollback if cpuset parsing fails afterwards.

virtPortProfile is now used by 4 different types of network devices (NETWORK, BRIDGE, DIRECT, and HOSTDEV), and it's getting cumbersome to replicate so much code in 4 different places just because each type has the virtPortProfile in a slightly different place. This patch puts a single virtPortProfile in a common place (outside the type-specific union) in both virDomainNetDef and virDomainActualNetDef, and adjusts the parse and format code (and the few other places where it is used) accordingly. Note that when a <virtualport> element is found, the parse functions verify that the interface is of a type that supports one, otherwise an error is generated (CONFIG_UNSUPPORTED in the case of <interface>, and INTERNAL in the case of <actual>, since the contents of <actual> are always generated by libvirt itself).

The meat of this patch is just moving the calls to virNWFilterRegisterCallbackDriver from each hypervisor's "register" function into its "initialize" function. The rest is just code movement to allow that, and a new virNWFilterUnRegisterCallbackDriver function to undo what the register function does. The long explanation: There is an array in nwfilter called callbackDrvArray that has pointers to a table of functions for each hypervisor driver that are called by nwfilter. One of those function pointers is to a function that will lock the hypervisor driver. Entries are added to the table by calling each driver's "register" function, which happens quite early in libvirtd's startup. Sometime later, each driver's "initialize" function is called. This function allocates a driver object and stores a pointer to it in a static variable that was previously initialized to NULL. (and here's the important part...) If the "initialize" function fails, the driver object is freed, and that pointer set back to NULL (but the entry in nwfilter's callbackDrvArray is still there). When the "lock the driver" function mentioned above is called, it assumes that the driver was successfully loaded, so it blindly tries to call virMutexLock on "driver->lock". BUT, if the initialize never happened, or if it failed, "driver" is NULL. And it just happens that "lock" is always the first field in driver so it is also NULL. Boom. To fix this, the call to virNWFilterRegisterCallbackDriver for each driver shouldn't be called until the end of its (*already guaranteed successful*) "initialize" function, not during its "register" function (which is currently the case). This implies that there should also be a virNWFilterUnregisterCallbackDriver() function that is called in a driver's "shutdown" function (although in practice, that function is currently never called).

Any time we have a string with no % passed through gettext, a translator can inject a % to cause a stack overread. When there is nothing to format, it's easier to ask for a string that cannot be used as a formatter, by using a trivial "%s" format instead. In the past, we have used --disable-nls to catch some of the offenders, but that doesn't get run very often, and many more uses have crept in. Syntax check to the rescue! The syntax check can catch uses such as virReportError(code, _("split " "string")); by using a sed script to fold context lines into one pattern space before checking for a string without %. This patch is just mechanical insertion of %s; there are probably several messages touched by this patch where we would be better off giving the user more information than a fixed string. * cfg.mk (sc_prohibit_diagnostic_without_format): New rule. * src/datatypes.c (virUnrefConnect, virGetDomain) (virUnrefDomain, virGetNetwork, virUnrefNetwork, virGetInterface) (virUnrefInterface, virGetStoragePool, virUnrefStoragePool) (virGetStorageVol, virUnrefStorageVol, virGetNodeDevice) (virGetSecret, virUnrefSecret, virGetNWFilter, virUnrefNWFilter) (virGetDomainSnapshot, virUnrefDomainSnapshot): Add %s wrapper. * src/lxc/lxc_driver.c (lxcDomainSetBlkioParameters) (lxcDomainGetBlkioParameters): Likewise. * src/conf/domain_conf.c (virSecurityDeviceLabelDefParseXML) (virDomainDiskDefParseXML, virDomainGraphicsDefParseXML): Likewise. * src/conf/network_conf.c (virNetworkDNSHostsDefParseXML) (virNetworkDefParseXML): Likewise. * src/conf/nwfilter_conf.c (virNWFilterIsValidChainName): Likewise. * src/conf/nwfilter_params.c (virNWFilterVarValueCreateSimple) (virNWFilterVarAccessParse): Likewise. * src/libvirt.c (virDomainSave, virDomainSaveFlags) (virDomainRestore, virDomainRestoreFlags) (virDomainSaveImageGetXMLDesc, virDomainSaveImageDefineXML) (virDomainCoreDump, virDomainGetXMLDesc) (virDomainMigrateVersion1, virDomainMigrateVersion2) (virDomainMigrateVersion3, virDomainMigrate, virDomainMigrate2) (virStreamSendAll, virStreamRecvAll) (virDomainSnapshotGetXMLDesc): Likewise. * src/nwfilter/nwfilter_dhcpsnoop.c (virNWFilterSnoopReqLeaseDel) (virNWFilterDHCPSnoopReq): Likewise. * src/openvz/openvz_driver.c (openvzUpdateDevice): Likewise. * src/openvz/openvz_util.c (openvzKBPerPages): Likewise. * src/qemu/qemu_cgroup.c (qemuSetupCgroup): Likewise. * src/qemu/qemu_command.c (qemuBuildHubDevStr, qemuBuildChrChardevStr) (qemuBuildCommandLine): Likewise. * src/qemu/qemu_driver.c (qemuDomainGetPercpuStats): Likewise. * src/qemu/qemu_hotplug.c (qemuDomainAttachNetDevice): Likewise. * src/rpc/virnetsaslcontext.c (virNetSASLSessionGetIdentity): Likewise. * src/rpc/virnetsocket.c (virNetSocketNewConnectUNIX) (virNetSocketSendFD, virNetSocketRecvFD): Likewise. * src/storage/storage_backend_disk.c (virStorageBackendDiskBuildPool): Likewise. * src/storage/storage_backend_fs.c (virStorageBackendFileSystemProbe) (virStorageBackendFileSystemBuild): Likewise. * src/storage/storage_backend_rbd.c (virStorageBackendRBDOpenRADOSConn): Likewise. * src/storage/storage_driver.c (storageVolumeResize): Likewise. * src/test/test_driver.c (testInterfaceChangeBegin) (testInterfaceChangeCommit, testInterfaceChangeRollback): Likewise. * src/vbox/vbox_tmpl.c (vboxListAllDomains): Likewise. * src/xenxs/xen_sxpr.c (xenFormatSxprDisk, xenFormatSxpr): Likewise. * src/xenxs/xen_xm.c (xenXMConfigGetUUID, xenFormatXMDisk) (xenFormatXM): Likewise.

The previous check for YAJL would have many undesirable consequences, the most important being that it caused the capabilities XML to lose all <guest> elements.
