Make the API fail less often by bumping the RPC message size and telling users
not to request stats for too many VMs until we figure out a better solution to
get a lot of stats.

[libvirt] [PATCH 1/1] vz: unlock dom until resize operation
by Konstantin Neumoin
We have to use waitDomainJob instead of waitJob, because of it
unlock the domain until job has finished, so domain will be available

[libvirt] [PATCH V2] libxl: add default controllers for USB devices
by Jim Fehlig
Attempting to start a domain with USB hostdevs but no USB controllers
fails with the rather cryptic error
libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an
error message from QMP server: Bus 'xenusb-0.0' not found
This can be fixed by creating default USB controllers. When no USB
controllers are defined, create the number of 8 port controllers
necessary to accommodate the number of defined USB devices.
Note that USB controllers are already created as needed in the
domainAttachDevice code path. E.g. a USB controller will be created,
if necessary, when attaching a USB device with
'virsh attach-device dom usbdev.xml'.

V1 here
https://www.redhat.com/archives/libvir-list/2017-April/msg00965.html
While further testing of V1 found a libvirtd segfault due to
incorrectly using virDomainControllerInsertPreAlloced instead of
virDomainControllerInsert.

[libvirt] [PATCH] qemu: Properly check return value of VIR_STRDUP in qemuDomainGetBlockIoTune
by Peter Krempa
Setting the 'group_name' for a disk would falsely trigger a error path
as in commit 4b57f76502 we did not properly check the return value of
VIR_STRDUP.

I must have forgotten to commit this change, as I'm sure I've tested it prior
to sending the patch mentioned above.
