Introduce a 'managed' attribute to allow libvirt to decide whether to
delete a vHBA vport created via external means such as nodedev-create.
The code currently decides whether to delete the vHBA based solely on
whether the parent was provided at creation time. However, that may not
be the desired action, so rather than delete and force someone to create
another vHBA via an additional nodedev-create allow the configuration of
the storage pool to decide the desired action.
During createVport when libvirt does the VPORT_CREATE, set the managed
value to YES if not already set to indicate to the deleteVport code that
it should delete the vHBA when the pool is destroyed.
If libvirtd is restarted all the memory only state was lost, so for a
persistent storage pool, use the virStoragePoolSaveConfig in order to
write out the managed value.
Because we're now saving the current configuration, we need to be sure
to not save the parent in the output XML if it was undefined at start.
Saving the name would cause future starts to always use the same parent
which is not the expected result when not providing a parent. By not
providing a parent, libvirt is expected to find the best available
vHBA port for each subsequent (re)start.
At deleteVport, use the new managed value to decide whether to execute
the VPORT_DELETE. Since we no longer save the parent in memory or in
XML when provided, if it was not provided, then we have to look it up.
Introduce the ability to save a configuration of a persistent configuration
that may be changed by storage pool backend activity, such as start or stop
Passing a copy of the storage pool adapter to a function just changes the
copy of the fields in the particular function and then when returning to
the caller those changes are discarded. While not yet biting us in the
storage clean-up case, it did cause an issue for the fchost storage pool
startup case, createVport. The issue was at startup, if no parent is found
in the XML, the code will search for the 'best available' parent and then
store that in the in memory copy of the adapter. Of course, in this case
it was a copy, so when returning to the virStorageBackendSCSIStartPool that
change was discarded (or lost) from the pool->def->source.adapter which
meant at shutdown (deleteVport), the code assumed no adapter was passed
and skipped the deletion, leaving the vHBA created by libvirt still defined
requiring an additional stop of a nodedev-destroy to remove.
Adjusted the createVport to take virStoragePoolDefPtr instead of the
adapter copy. Then use the virStoragePoolSourceAdapterPtr when processing.
A future patch will need the 'def' anyway, so this just sets up for that.
The existing code assumed that the configuration of a 'parent' attribute
was correct for the createVport path. As it turns out, that may not be
the case which leads errors during the deleteVport path because the
wwnn/wwpn isn't associated with the parent.
With this change the following is reported:
error: Failed to start pool fc_pool_host3
error: XML error: Parent attribute 'scsi_host4' does not match parent 'scsi_host3' determined for the 'scsi_host16' wwnn/wwpn lookup.
If a 'parent' attribute is provided for the fchost, then at startup
time check to ensure it is a vport capable scsi_host. If the parent
is not vport capable, then disallow the startup. The following is the
expected results:
error: Failed to start pool fc_pool
error: XML error: parent 'scsi_host2' specified for vHBA is not vport capable
Providing an incorrect parent and a correct wwnn/wwpn could lead to
failures at shutdown (deleteVport) where the assumption is the parent
is for the fchost.
NOTE: If the provided wwnn/wwpn doesn't resolve to an existing scsi_host,
then we will be creating one with code (virManageVport) which
assumes the parent is vport capable.
I could have just remove bool supportMaxOptions variable, but
if I had do this, we could not check anymore if the nparams variable is
superior to QEMU_NB_BLOCK_IO_TUNE_PARAM_MAX.

For inexplicable reasons the phyp driver defined two separate
structs for holding its private data. One it keeps in privateData
and the other it keeps in networkPrivateData. It uses them both
from all API driver methods. Merge the two separate structs
into one to remove this horrible abuse.

The remote driver has had a long term hack to deal with the fact
that the old Xen driver worked outside libvirtd, but the rest
of the drivers worked inside. So you could have a local hypervisor
driver but everything else go via the remote driver. The Xen driver

PowerPC:Improve PVR handling to fall back to cpu generation.
IBM Power processors differ uniquely across generations (such as power6,

The higher 16 bits of PVR for IBM Power processors encode the CPU
generation, while the CPU chip (sub)version is encoded in lower 16 bits.

generation which the vCPU will belong to, and not specifically the chip
version. This patch updates the libvirt PVR check to reflect this
relationship. It allows libvirt to select the right CPU generation

Iface: disallow network tuning in session mode globally
Patch 43b67f2e disallowed network tuning only with qemu driver, however
this patch moved the check for root privileges into
virNetDevBandwidthSet function, so the call should now
fail in all possible cases. A mock function was created so that the test
suite doesn't fail because of unsufficient privileges.

qemu: revert patch - bandwidth tuning in session mode
Since there was a valid note to patch 43b67f2e about the best spot to
check for bandwidth set call while having libvirt daemon run in session
mode, this patch reverts previous changes dealing with bandwith
(also reverts adding variable @cfg in qemuDomainGetNumaParameters which
does not have any use at the moment, but getting and unreferencing
driver's config) in qemu_driver.c and qemu_command.c. There will be
another patch in the series which introduces the fix itself.
