[libvirt] [PATCH 0/5] Use memfd if possible
From: Marc-André Lureau <marcandre.lureau(a)redhat.com>
Hi,
This is an alternative to "[RFC v2 02/16] qemu: add memfd memory
backing", which added a new source type. Instead, Daniel suggested to
automatically use memfd for anonymous memory when available.
Marc-André Lureau (5):
qemu: add memory-backend-memfd capability check
qemu: check memory-backend-memfd.hugetlb capability
qemu: prefer memfd for anonymous memory
conf: drop hugepage non-anoymous memory requirement
tests: add qemuxml2argv memfd-memory-numa test
