A few commits ago new APIs were introduced (virDomainSaveParams()
and virDomainRestoreParams()) and with them new typed parameters:
VIR_SAVE_PARAM_FILE and VIR_SAVE_PARAM_DXML. But their name does
not suggest they apply to either of the APIs nor that they are
intended for domain related APIs. Switch to
VIR_DOMAIN_SAVE_PARAM prefix to make it obvious.
It's true we already have VIR_DOMAIN_SAVE_* symbols which are
part of virDomainSaveRestoreFlags enum, therefore stick also with
'_PARAM_ ' part of the name to differentiate the two.

is merged to Qemu master branch and should be available with Qemu 7.1.
This is used to get the signed Chip Endorsement Key (CEK) of the CPU of AMD

Similar to cbitpos, reducedPhysBits, maxGuests & maxESGuests;
the value of cpu0-id is also provided using 'virsh domcapability'.

virConnectAuthPtrDefault is the only variable that we export and
with the documentation being at the C file, it makes harder to find
it.
With this patch, the documentation of this variable can be found by
those who look at the header file for guidance plus, it will also be
included in the XML API, as the followup patch will fix apibuild.py
to store what is documented in the header file for this variable.
Note that the apibuild, does not do the same with .c files. It'd
require adding it for (parsing) recursion, similar to what is done
for functions. Considering the pros/cons, seems more reasonable to
move the docstring to the header file instead.

When starting a guest with pflash based firmware, we will initialize
NVRAM from a template if it does not already exist. In theory if the
firmware code file is updated, the existing NVRAM variables should
continue to work correctly. It is inevitable that this could break
accidentally one day. Or a bug in the firmware might corrupt the
NVRAM storage. Or user might make bad changes to the settings that
prevent booting. Or the user might have re-configured the XML to
point to a different firmware file incompatible with the current
variables.
In all these cases it would be useful to delete the existing NVRAM
and initialize it from the pristine template.
To support this introduce a VIR_DOMAIN_START_RESET_NVRAM constant
for use with virDomainCreate / virDomainCreateXML, along with
VIR_DOMAIN_SAVE_RESET_NVRAM for use with virDomainRestore and
VIR_DOMAIN_SNAPSHOT_REVERT_RESET_NVRAM for use with
virDomainSnapshotRevert.

Non-shared storage migration of guests which are disk I/O intensive and
have fast local storage may actually never converge if the guest happens
to dirty the disk faster than it can be copied.
This patch introduces a new flag
'VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES' which will instruct
hypervisors to synchronize local I/O writes with the writes to remote
storage used for migration so that the guest can't overwhelm the
migration. This comes at a cost of decreased local I/O performance for
guests which behave well on average.

In cases when the destination storage is slower than the normal VM
storage and the VM does intensive I/O to the disk a block copy job may
never converge.
Switching it to synchronous mode will ensure that all writes done by the

of the guest to the synchronous speed.

It comes with one attribute - size - which holds the new size of

Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.
