qemu: Store all iothread's 'poll*' attributes as unsigned long long

2023-05-02T12:32:47+00:00

Convert the internal types to unsigned long long. Luckily we can also
covert the external types too:

 - 'qemuDomainSetIOThreadParams' can accept both _UINT and _ULLONG by
   converting to 'virTypedParamsGetUnsigned'

 - querying is handled via the bulk stats API which is flexible:
    - we use virTypedParamListAddUnsigned to use the bigger type only if
      necessary
    - most users don't even notice because the bindings abstract the
      data types

Apart from the code modifications we also improve the documentation
which was missing for the setters.

Introduce VIR_DOMAIN_PAUSED_API_ERROR

2023-03-15T09:52:14+00:00

Some APIs (migration, save/restore, snapshot, ...) require a domain to
be suspended temporarily. In case resuming the domain fails, the domain
will be unexpectedly left paused when the API finishes. This situation
is reported via VIR_DOMAIN_EVENT_SUSPENDED event with
VIR_DOMAIN_EVENT_SUSPENDED_API_ERROR detail. But we do not have a
corresponding reason for VIR_DOMAIN_PAUSED state and the reason would
remain set to the value used when the domain was paused. So the state
reason would suggest the operation is still running.

This patch changes the state reason to a new VIR_DOMAIN_PAUSED_API_ERROR
to make it clear the API that paused the domain already finished, but
failed to resume the domain.

lib: Introduce virDomainFDAssociate API

2023-01-09T13:59:42+00:00

The API can be used to associate one or more (e.g. a RO and RW fd for a
disk backend image) FDs to a VM. They can be then used per definition.

The primary use case for now is for complex deployment where
libvirtd/virtqemud may be run inside a container and getting the image
into the container is complicated.

In the future it will also allow passing e.g. vhost FDs and other
resources to a VM without the need to have a filesystem representation
for it.

Passing raw FDs has few intricacies and thus libvirt will by default not
restore security labels.

qemu: Add UNDEFINE_TPM and UNDEFINE_KEEP_TPM flags

2022-10-04T14:34:28+00:00

Add UNDEFINE_TPM and UNDEFINE_KEEP_TPM flags to qemuDomainUndefineFlags()
API and --tpm and --keep-tpm to 'virsh undefine'. Pass the
virDomainUndefineFlagsValues via qemuDomainRemoveInactive()
from qemuDomainUndefineFlags() all the way down to
qemuTPMEmulatorCleanupHost() and delete TPM storage there considering that
the UNDEFINE_TPM flag has priority over the persistent_state attribute
from the domain XML. Pass 0 in all other API call sites to
qemuDomainRemoveInactive() for now.
