There was a crash possible when both <boot dev... and <boot order... were specified due to virDomainDefParseBootXML() erroring out before setting *tmp (which was free'd in cleanup). As a fix, I created this cleanup that uses one pointer for all the temporary stored XPath strings and values, plus this pointer is correctly initialized to NULL.

BZ:https://bugzilla.redhat.com/show_bug.cgi?id=851981 When using macvtap, a character device gets first created by kernel with name /dev/tapN, its selinux context is: system_u:object_r:device_t:s0 Shortly, when udev gets notification when new file is created in /dev, it will then jump in and relabel this file back to the expected default context: system_u:object_r:tun_tap_device_t:s0 There is a time gap happened. Sometimes, it will have migration failed, AVC error message: type=AVC msg=audit(1349858424.233:42507): avc: denied { read write } for pid=19926 comm="qemu-kvm" path="/dev/tap33" dev=devtmpfs ino=131524 scontext=unconfined_u:system_r:svirt_t:s0:c598,c908 tcontext=system_u:object_r:device_t:s0 tclass=chr_file This patch will label the tapfd device before qemu process starts: system_u:object_r:tun_tap_device_t:MCS(MCS from seclabel->label)

This patch adds support for SUSPEND_DISK event; both lifecycle and separated. The support is added for QEMU, machines are changed to PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes to shut-off. This and much more needs to be done in order for libvirt to work with transient devices, wake-ups etc. This patch is not aiming for that functionality.

Upstream kernel introduced new sysfs knob "merge_across_nodes" to specify if pages from different numa nodes can be merged. When set to 0, only pages which physically reside in the memory area of same NUMA node can be merged. When set to 1, pages from all nodes can be merged. This patch supports the tuning by adding new param field "shm_merge_across_nodes".

This patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=805071 to the extent that it can be resolved with current qemu functionality. It attempts to detect as many situations as possible when the simple operation of disconnecting an existing tap device from one bridge and attaching it to another will satisfy the change requested in virDomainUpdateDeviceFlags() for a network device. Before this patch, that situation could only be detected if the pre-change interface *and* the post-change interface definition were both "type='bridge'". After this patch, it can also be detected if the before or after interfaces are any combination of type='bridge' and type='network' (the networks can be <forward mode='nat|route|bridge'>, as long as they use a Linux host bridge and not macvtap connections). This extra effort is especially useful since the recent discovery that a netdev_del+netdev_add combo (to reconnect the network device with completely different hostside configuration) doesn't work properly with current qemu (1.2) unless it is accompanied by the matching device_del+device_add - see this mailing list message for details: http://lists.nongnu.org/archive/html/qemu-devel/2012-10/msg02355.html (A slight modification of the patch referenced there has been prepared to apply on top of this patch, but won't be pushed until qemu can be made to work with it.) * qemuDomainChangeNet needs access to the virDomainDeviceDef that holds the new netdef (so that it can clear out the virDomainDeviceDef if it ends up using the NetDef to replace the original), so the virDomainNetDefPtr arg is replaced with a virDomainDeviceDefPtr. * qemuDomainChangeNet previously checked for *some* changes to the interface config, but this check was by no means complete. It was also a bit disorganized. This refactoring of the code is (I believe) complete in its check of all NetDef attributes that might be changed, and either returns a failure (for changes that are simply impossible), or sets one of three flags: needLinkStateChange - if the device link state needs to go up/down needBridgeChange - if everything else is the same, but it needs to be connected to a difference linux host bridge needReconnect - if the entire host side of the device needs to be torn down and reconstructed (currently non-working, as mentioned above) Note that this function will refuse to make any change that requires the *guest* side of the device to be detached (e.g. changing the PCI address or mac address). Those would be disruptive enough to the guest that it's reasonable to require an explicit detach/attach sequence from the management application. * As mentioned above, qemuDomainChangeNet also does its best to understand when a simple change in attached bridge for the existing tap device will work vs. the need to completely tear down/reconstruct the host side of the device (including tap device). This patch *does not* implement the "reconnect" code anyway - there is a placeholder that turns that into an error. Rather, the purpose of this patch is to replicate existing behavior with code that is ready to have that functionality plugged in in a later patch. * The expanded uses for qemuDomainChangeNetBridge meant that it needed to be enhanced as well - it no longer replaces the original brname string in olddev with the new brname; instead, it relies on the caller to replace the *entire* olddev with newdev (since we've gone to great lengths to assure they are functionally identical other than the name of the bridge, this is now not only safe, but more correct). Additionally, qemuDomainNetChangeBridge can now set the bridge for type='network' interfaces as well as plain type='bridge' interfaces. (Note that I had to make this change simultaneous to the reorganization of qemuDomainChangeNet because the two are too closely intertwined to separate).

This function really should have been taking virDevicePCIAddress* instead of the inefficient virDevicePCIAddress (results in copying two entire structs onto the stack rather than just two pointers), and returning a bool true/false (not matching is not necessarily a "failure", as a -1 return would imply, and also using "if (!virDevicePCIAddressEqual(x, y))" to mean "if x == y" is just a bit counterintuitive).

If the vcpu placement is "static", it's just fine to ignore the def->cpumask if emulatorpin is specified.
-
由 Osier Yang 提交于
When vcpu placement is "auto", the domain process will be pinned to advisory nodeset from querying numad, While emulatorpin will override the pinning. That means both of them are to set the pinning policy for domain process, but conflicts with each other. This patch ingore emulatorpin if vcpu placement is "auto", because <vcpu> placement can't be simply ignored for <numatune> placement could default to it.

由 Osier Yang 提交于
The onlined vcpu pinning policy should inherit def->cpuset if it's not specified explicitly, and the affinity should be set in this case. Oppositely, the offlined vcpu pinning policy should be free()'ed.

Various APIs use cgroup to either set or get the statistics of host or guest. Hotplug or hot unplug new vcpus without creating or removing the cgroup for the vcpus could cause problems for those APIs. E.g. % virsh vcpucount dom maximum config 10 maximum live 10 current config 1 current live 1 % virsh setvcpu dom 2 % virsh schedinfo dom --set vcpu_quota=1000 Scheduler : posix error: Unable to find vcpu cgroup for rhel6.2(vcpu: 1): No such file or directory This patch fixes the problem by creating cgroups for each of the onlined vcpus, and destroying cgroups for each of the offlined vcpus.

Document for <vcpu>'s "cpuset" says: Since 0.4.4, this element can contain an optional cpuset attribute, which is a comma-separated list of physical CPU numbers that virtual CPUs can be pinned to. However, it's not the truth, libvirt actually pins the domain process to the specified pCPUs by "cpuset" of <vcpu>. And the vcpu thread are pinned to all available pCPUs if no <vcpupin> is specified for it. This patch is to implement the codes to inherit <vcpu>'s "cpuset" for vcpu that doesn't have <vcpupin> specified, and <vcpupin> for these vcpu will be ignored when formating. Underlying driver implementation will make sure the vcpu thread pinned to correct pCPUs.

Setting pinning policy for vcpu which exceeds current vcpus number just makes no sense, however, it could cause various problems, E.g. <vcpu current='1'>4</vcpu> <cputune> <vcpupin vcpuid='3' cpuset='4'/> </cputune> % virsh start linux error: Failed to start domain linux error: cannot set CPU affinity on process 32534: No such process We must have some odd codes underlying which produces the "on process 32534", but the point is why we not to prevent earlier when parsing? Note that this is only one of the problem it could cause. This patch is to ignore the <vcpupin> for not onlined vcpus.

These 3 elements conflicts with each other in either the doc or the underlying codes. Current problems: Problem 1: The doc shouldn't simply say "These settings are superseded by CPU tuning. " for element <vcpu>. As except the tuning, <vcpu> allows to specify the current, maxmum vcpu number. Apart from that, <vcpu> also allows to specify the placement as "auto", which binds the domain process to the advisory nodeset from numad. Problem 2: Doc for <vcpu> says its "cpuset" specify the physical CPUs that the vcpus can be pinned. But it's not the truth, as actually it only pin domain process to the specified physical CPUs. So either it's a document bug, or code bug. Problem 3: Doc for <vcpupin> says it supersed "cpuset" of <vcpu>, it's not quite correct, as each <vcpupin> specify the pinning policy only for one vcpu. How about the ones which doesn't have <vcpupin> specified? it says the vcpu will be pinned to all available physical CPUs, but what's the meaning of attribute "cpuset" of <vcpu> then? Problem 4: Doc for <emulatorpin> says it pin the emulator threads (domain process in other context, perhaps another follow up patch to cleanup the inconsistency is needed) to the physical CPUs specified its attribute "cpuset". Which conflicts with <vcpu>'s "cpuset". And actually in the underlying codes, it set the affinity for domain process twice if both "cpuset" for <vcpu> and <emulatorpin> are specified, and <emulatorpin>'s pinning will override <vcpu>'s. Problem 5: When "placement" of <vcpu> is "auto" (I.e. uses numad to get the advisory nodeset to which the domain process is pinned to), it will also be overridden by <emulatorpin>, This patch is trying to sort out the conflicts or bugs by: 1) Don't say <vcpu> is superseded by <cputune> 2) Keep the semanteme for "cpuset" of <vcpu> (I.e. Still says it specify the physical CPUs the virtual CPUs). But modifying it to mention it also set the pinning policy for domain process, and the CPU placement of domain process specified by "cpuset" of <vcpu> will be ingored if <emulatorpin> specified, and similary, the CPU placement of vcpu thread will be ignored if it has <vcpupin> specified, for vcpu which doesn't have <vcpupin> specified, it inherits "cpuset" of <vcpu>. 3) Don't say <vcpu> is supersed by <vcpupin>. If neither <vcpupin> nor "cpuset" of <vcpu> is specified, the vcpu will be pinned to all available pCPUs. 4) If neither <emulatorpin> nor "cpuset" of <vcpu> is specified, the domain process (emulator threads in the context) will be pinned to all available pCPUs. 5) If "placement" of <vcpu> is "auto", <emulatorpin> is not allowed. 6) hotplugged vcpus will also inherit "cpuset" of <vcpu> Codes changes according to above document changes: 1) Inherit def->cpumask for each vcpu which doesn't have <vcpupin> specified, during parsing. 2) ping the vcpu which doesn't have <vcpupin> specified to def->cpumask either by cgroup for sched_setaffinity(2), which is actually done by 1). 3) Error out if "placement" == "auto", and <emulatorpin> is specified. Otherwise, <emulatorpin> is honored, and "cpuset" of <cpuset> is ignored. 4) Setup cgroup for each hotplugged vcpu, and setup the pinning policy by either cgroup or sched_setaffinity(2). 5) Remove cgroup and <vcpupin> for each hot unplugged vcpu.

We are currently able to work only with non-translated SELinux contexts, but we are using functions that work with translated contexts throughout the code. This patch swaps all SELinux context translation relative calls with their raw sisters to avoid parsing problems. The problems can be experienced with mcstrans for example. The difference is that if you have translations enabled (yum install mcstrans; service mcstrans start), fgetfilecon_raw() will get you something like 'system_u:object_r:virt_image_t:s0', whereas fgetfilecon() will return 'system_u:object_r:virt_image_t:SystemLow' that we cannot parse. I was trying to confirm that the _raw variants were here since the dawn of time, but the only thing I see now is that it was imported together in the upstream repo [1] from svn, so before 2008. Thanks Laurent Bigonville for finding this out. [1] http://oss.tresys.com/git/selinux.git

The comment stated that you may call qemuDomainObjBeginJobWithDriver without passing qemud_driver to signal it's not locked. qemuDomainObjBeginJobWithDriver still accesses the qemud_driver structure and the lock singaling is done through a separate parameter.

Save/restore with passed through USB devices currently only works if the USB device can be found at the same USB address where it used to be before saving a domain. This makes sense in case a user explicitly configure the USB address in domain XML. However, if the device was found automatically by vendor/product identification, we should try to search for that device when restoring the domain and use any device we find as long as there is only one available. In other words, the USB device can now be removed and plugged again or the host can be rebooted between saving and restoring the domain.

Using VIR_DOMAIN_XML_MIGRATABLE flag, one can request domain's XML configuration that is suitable for migration or save/restore. Such XML may contain extra run-time stuff internal to libvirt and some default configuration may be removed for better compatibility of the XML with older libvirt releases. This flag may serve as an easy way to get the XML that can be passed (after desired modifications) to APIs that accept custom XMLs, such as virDomainMigrate{,ToURI}2 or virDomainSaveFlags.

USB devices can disappear without OS being mad about it, which makes them ideal for startupPolicy. With this attribute, USB devices can be configured to be mandatory (the default), requisite (will disappear during migration if they cannot be found), or completely optional.
