Subject: [PATCH] conf: Make VIR_DOMAIN_NET_TYPE_ETHERNET not share 'host view'
When setting up QoS for a domain <interface/>, or when reporting
its statistics we may need to swap TX/RX values. This is all
explained in comment to virDomainNetTypeSharesHostView().
However, this function claims that VIR_DOMAIN_NET_TYPE_ETHERNET
also shares the 'host view', meaning the TX/RX values must be
swapped. But that's not true.
An easy reproducer is to start a domain with two <interface/>-s:
one type of network, the other of type ethernet and configure the
same <bandwidth/> for both. Reversed setting can then be observed
(e.g. via tc).

Subject: [PATCH] lib: Set up cpuset controller for restrictive numatune
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The aim of 'restrictive' numatune mode is to rely solely on
CGroups to have QEMU running on configured NUMA nodes. However,
we were never setting the cpuset controller when a domain was
starting up. We are doing so only when
virDomainSetNumaParameters() is called (aka live pinning).
This is obviously wrong. Fortunately, fix is simple as
'restrictive' is similar to 'strict' - every location where
VIR_DOMAIN_NUMATUNE_MEM_STRICT occurs can be audited and
VIR_DOMAIN_NUMATUNE_MEM_RESTRICTIVE case can be added.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
The virNodeDeviceGetPCIVPDDynamicCap() function is called from
virNodeDeviceGetPCIDynamicCaps() and therefore has to be a wee
bit more clever about adding VPD capability. Namely, it has to
remove the old one before adding a new one. This is how other
functions called from virNodeDeviceGetPCIDynamicCaps() behave
as well.

Subject: [PATCH] qemu: agent: Make fetching of 'can-offline' member from
'guest-query-vcpus' optional
The 'can-offline' member is optional according to agent's schema and in
fact in certain cases it's not returned. Libvirt then spams the logs
if something is polling the bulk guest stats API.
Noticed when going through oVirt logs which appears to call the bulk
stats API repeatedly.
Instead of requiring it we simply reply that the vCPU can't be offlined.

Subject: [PATCH] qemu: domain: Fix logic when tainting domain
Originally the code was skipping all repeated taints with the same taint
flag but a logic bug introduced in commit 30626ed15b239c424ae inverted
the condition. This caused that actually the first occurence was NOT
logged but any subsequent was.
This was noticed when going through oVirt logs as they use custom guest
agent commands and the logs are totally spammed with this message.

In order to mock the SCM_RIGHTS sendmsg to simulate sending
filedescriptors to fake qemu in tests we need access to some fields of
'struct _qemuMonitor'. Move its declaration to the private header file.

Rather than having callers always pass this flag store it in the

internal flag.
In the future this will also simplify removal when all supported qemu
versions will support the new mode.

Subject: [PATCH] qemu: relax shared memory check for vhostuser daemons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For some vhostuser daemons, we validate that the guest memory is shared
with the host.
With earlier versions of QEMU, it was only possible to mark memory
as shared by defining an explicit NUMA topology. Later, QEMU exposed
the name of the default memory backend (defaultRAMid) so we can mark
that memory as shared.
Since libvirt commit:
commit bff2ad5d6b1f25da02802273934d2a519159fec7
qemu: Relax validation for mem->access if guest has no NUMA
we already check for the case when user requests shared memory,
but QEMU did not expose defaultRAMid.
Drop the duplicit check from vhostuser device validation, to make
it pass on hotplug even after libvirtd restart.
This avoids the need to store the defaultRAMid, since we don't really
need it for anything after the VM has been already started.

'query-named-block-nodes' in non-flat mode returns redundantly nested
data under the 'backing-image' field. Fortunately we don't need it when
updating the capacity stats.
This function was unfortunately not fixed originally when the support
for flat mode was added. Use the flat cached in the monitor object to
force flat mode if available.
