This breaks vCPU hotplug, because when starting a domain, we create a copy of domain definition (which becomes live XML) and during the post parse callbacks we might adjust some tunings so that vCPU hotplug is possible. This reverts commit 581b7756.

When creating a copy of virDomainDef we save ourselves the trouble of writing deep-copy functions and just format and parse back domain/device XML. However, the XML we are parsing was already fully formatted - there is no reason to run post parse callbacks (which fill in blanks - there are none!).

We can't rely on def->emulator path. It may be provided by user as we give them opportunity to provide their own XML for migration. Therefore the path may point to just whatever binary (or even to a non-existent file). Moreover, this path is meant for destination, but the capabilities lookup is done on source. What we can do is to assume same capabilities for post parse callbacks as the running domain has. They will be used just to add some default models/controllers/devices/... anyway.

Some callers might want to pass yet another pointer to opaque data to post parse callbacks. The driver generic one is not enough because two threads executing post parse callback might want to see different data (e.g. domain object pointer that domain def belongs to).

Storing the updated CPU definition in the live domain definition saves us from having to update it over and over when we need it. Not to mention that we will soon further update the CPU definition according to QEMU once it's started. A highly wanted side effect of this patch, libvirt will pass all CPU features explicitly specified in domain XML to QEMU, even those that are already included in the host model. This patch should fix the following bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1207095 https://bugzilla.redhat.com/show_bug.cgi?id=1339680 https://bugzilla.redhat.com/show_bug.cgi?id=1371039 https://bugzilla.redhat.com/show_bug.cgi?id=1373849 https://bugzilla.redhat.com/show_bug.cgi?id=1375524 https://bugzilla.redhat.com/show_bug.cgi?id=1377913Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

The reworked API is now called virCPUUpdate and it should change the provided CPU definition into a one which can be consumed by the QEMU command line builder: - host-passthrough remains unchanged - host-model is turned into custom CPU with a model and features copied from host - custom CPU with minimum match is converted similarly to host-model - optional features are updated according to host's CPU Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

Use the state information (online, hotpluggable) provided by the monitor code rather than trying to infer it. This fixes an issue where on architectures that require hotplug of multiple threads at once the sub-cores would get updated as offline on daemon restart thus creating an invalid configuration.

When migration fails, we need to poke QEMU monitor to check for a reason of the failure. We did this using query-migrate QMP command, which is not supposed to return any meaningful result on the destination side. Thus if the monitor was still functional when we detected the migration failure, parsing the answer from query-migrate always failed with the following error message: "info migration reply was missing return status" This irrelevant message was then used as the reason for the migration failure replacing any message we might have had. Let's use harmless query-status for poking the monitor to make sure we only get an error if the monitor connection is broken. https://bugzilla.redhat.com/show_bug.cgi?id=1374613Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

https://bugzilla.redhat.com/show_bug.cgi?id=1366989 QEMU added another virtio-net tunable [1]. It basically allows users to set the size of RX virtio ring. But because virtio-net uses two separate ring buffers to pass data from/to guest they named it explicitly rx_queue_size.

Since the domain lock is not held during preparation of an external XML config, it is possible that the value can change resulting in unexpected failures during ABI consistency checking for some save and migrate operations. This patch adds a new flag to skip the checking of the cur_balloon value and then sets the destination value to the source value to ensure subsequent checks without the skip flag will succeed. This way it is protected from forges and is keeped up to date too. Signed-off-by: NNikolay Shirokovskiy <nshirokovskiy@virtuozzo.com>

Add support for using the new approach to hotplug vcpus using device_add during startup of qemu to allow sparse vcpu topologies. There are a few limitations imposed by qemu on the supported configuration: - vcpu0 needs to be always present and not hotpluggable - non-hotpluggable cpus need to be ordered at the beginning - order of the vcpus needs to be unique for every single hotpluggable entity Qemu also doesn't really allow to query the information necessary to start a VM with the vcpus directly on the commandline. Fortunately they can be hotplugged during startup. The new hotplug code uses the following approach: - non-hotpluggable vcpus are counted and put to the -smp option - qemu is started - qemu is queried for the necessary information - the configuration is checked - the hotpluggable vcpus are hotplugged - vcpus are started This patch adds a lot of checking code and enables the support to specify the individual vcpu element with qemu.

The vcpu order information is extracted only for hotpluggable entities, while vcpu definitions belonging to the same hotpluggable entity need to all share the order information. We also can't overwrite it right away in the vcpu info detection code as the order is necessary to add the hotpluggable vcpus enabled on boot in the correct order. The helper will store the order information in places where we are certain that it's necessary.

Introduce a new migration cookie flag that will be used for any configurations that are not compatible with libvirt that would not support the specific vcpu hotplug approach. This will make sure that old libvirt does not fail to reproduce the configuration correctly.

Individual vCPU hotplug requires us to track the state of any vCPU. To allow this add the following XML: <domain> ... <vcpu current='2'>3</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no' order='1'/> <vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/> <vcpu id='1' enabled='no' hotpluggable='yes'/> </vcpus> ... The 'enabled' attribute allows to control the state of the vcpu. 'hotpluggable' controls whether given vcpu can be hotplugged and 'order' allows to specify the order to add the vcpus.

Similarly to devices the guest may allow unplug of the VCPU if libvirt is down. To avoid problems, refresh the vcpu state on reconnect. Don't mess with the vcpu state otherwise.

Now that the monitor code gathers all the data we can extract it to relevant places either in the definition or the private data of a vcpu. As only thread id is broken for TCG guests we may extract the rest of the data and just skip assigning of the thread id. In case where qemu would allow cpu hotplug in TCG mode this will make it work eventually.

For hotplug purposes it's necessary to retrieve data using query-hotpluggable-cpus while the old query-cpus API report thread IDs and order of hotplug. This patch adds code that merges the data using a rather non-trivial algorithm and fills the data to the qemuMonitorCPUInfo structure for adding to appropriate place in the domain definition.

When the user doesn't specify any model for a USB controller, we use an architecture-dependent default, but we don't reflect it in the guest XML. Pick the default USB controller model when parsing the guest XML instead of when creating the QEMU command line, so that our choice is saved back to disk.

In qemu, enabling this feature boils down to adding the following onto the command line: -global driver=cfi.pflash01,property=secure,value=on However, there are some constraints resulting from the implementation. For instance, System Management Mode (SMM) is required to be enabled, the machine type must be q35-2.4 or later, and the guest should be x86_64. While technically it is possible to have 32 bit guests with secure boot, some non-trivial CPU flags tuning is required (for instance lm and nx flags must be prohibited). Given complexity of our CPU driver, this is not trivial. Therefore I've chosen to forbid 32 bit guests for now. If there's ever need, we can refine the check later.
