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.

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.
