Historically QEMU/LXC guests have been placed in a cgroup layout that is $LOCATION-OF-LIBVIRTD/libvirt/{qemu,lxc}/$VMNAME This is bad for a number of reasons - The cgroup hierarchy gets very deep which seriously impacts kernel performance due to cgroups scalability limitations. - It is hard to setup cgroup policies which apply across services and virtual machines, since all VMs are underneath the libvirtd service. To address this the default cgroup location is changed to be /system/$VMNAME.{lxc,qemu}.libvirt This puts virtual machines at the same level in the hierarchy as system services, allowing consistent policy to be setup across all of them. This also honours the new resource partition location from the XML configuration, for example <resource> <partition>/virtualmachines/production</partitions> </resource> will result in the VM being placed at /virtualmachines/production/$VMNAME.{lxc,qemu}.libvirt NB, with the exception of the default, /system, path which is intended to always exist, libvirt will not attempt to auto-create the partitions in the XML. It is the responsibility of the admin/app to configure the partitions. Later libvirt APIs will provide a way todo this. Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Rename all the virCgroupForXXX methods to use the form virCgroupNewXXX since they are all constructors. Also make sure the output parameter is the last one in the list, and annotate all pointers as non-null. Fix up all callers, and make sure they use true/false not 0/1 for the boolean parameters Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Instead of calling virCgroupForDomain every time we need the virCgrouPtr instance, just do it once at Vm startup and cache a reference to the object in qemuDomainObjPrivatePtr until shutdown of the VM. Removing the virCgroupPtr from the QEMU driver state also means we don't have stale mount info, if someone mounts the cgroups filesystem after libvirtd has been started Signed-off-by: NDaniel P.

Use the helper to lookup the domain object in the remaining places. This patch also fixes error reporting when the domain was not found in several functions that were printing the raw UUID buffer instead of the formatted string. The offending functions were: qemuDomainGetInterfaceParameters qemuDomainSetInterfaceParameters qemuGetSchedulerParametersFlags qemuSetSchedulerParametersFlags qemuDomainGetNumaParameters qemuDomainSetNumaParameters qemuDomainGetMemoryParameters qemuDomainSetMemoryParameters qemuDomainGetBlkioParameters qemuDomainSetBlkioParameters qemuDomainGetCPUStats

Probe for QEMU's QMP TPM support by querying the lists of supported TPM models (query-tpm-models) and backend types (query-tpm-types). The setting of the capability flags following the strings returned from the commands above is only provided in the patch where domain_conf.c gets TPM support due to dependencies on functions only introduced there.

To avoid the collision for creating USB controllers in machine->init() and -device xx command line, it needs to set usb=off to avoid one USB controller created in machine->init(). So that libvirt can use -device or -usb to create USB controller sucessfully. So QEMU_CAPS_MACHINE_USB_OPT capability is added, and it is for QEMU v1.3.0 onwards which supports USB option.

https://bugzilla.redhat.com/show_bug.cgi?id=920441 Currently, we are discarding listen attribute from qemu cookie even though we strive to gather it. This result in not so cool bug: if user have different networks, one for management/migration, and one for VNC/SPICE we pass incorrect host to the qemu in client_migrate_info. What we actually pass is remote hostname, while we should be passing remote listen address. It doesn't matter as long as these two are the same, but they don't need necessary to be like that.

The virCgroupMounted method is badly named, since a controller can be mounted, but disabled in the current object. Rename the method to be virCgroupHasController. Also make it tolerant to a NULL virCgroupPtr and out-of-range controller index, to avoid duplication of these checks in all callers Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Since the source is already translated before. This just adds the checking. Move !disk->shared and !disk->src to improve the performance a bit.
-
由 Osier Yang 提交于
To support "shareable" for volume type disk, we have to translate the source before trying to add the shared disk entry. To achieve the goal, this moves the helper qemuTranslateDiskSourcePool into src/qemu/qemu_conf.c, and introduce an internal only member (voltype) for struct _virDomainDiskSourcePoolDef, to record the underlying volume type for use when building the drive string. Later patch will support "shareable" volume type disk.

"startupPolicy" is only valid for file type storage volume, otherwise it fails on starting the domain.
-
由 Osier Yang 提交于
This adds a new helper qemuTranslateDiskSourcePool which uses the storage pool/vol APIs to translate the disk source before building the drive string. Network volume is not supported yet. Disk chain for volume type disk may be supported later, but before I'm confident it doesn't break anything, it's just disabled now.

Currently when getting an instance of virCgroupPtr we will create the path in all cgroup controllers. Only at the virt driver layer are we attempting to filter controllers. This is bad because the mere act of creating the dirs in the controllers can have a functional impact on the kernel, particularly for performance. Update the virCgroupForDriver() method to accept a bitmask of controllers to use. Only create dirs in the controllers that are requested. When creating cgroups for domains, respect the active controller list from the parent cgroup Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

This patch refactors various places to allow removing of the defaultConsoleTargetType callback from the virCaps structure. A new console character device target type is introduced - VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was specified in the XML. This type is at the end converted to the standard VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are different from this default have to be processed separately in the device post parse callback.

This patch removes the emulatorRequired field and associated infrastructure from the virCaps object. Instead the driver specific callbacks are used as this field isn't enforced by all drivers.

This patch removes the defaultDiskDriverName from the virCaps structure. This particular default value is used only in the qemu driver so this patch uses the recently added callback to fill the driver name if it's needed instead of propagating it through virCaps.
