While this is not strictly required for blockdev to work it was created
as a part of the testing (and possibly regression mitigation) effort.

These patches introduce the option to add or remove qemu capabilities
via the qemu XML namespace custom elements and remove features via
qemu.conf.

This series depends (very slightly) on the series deleting qemu parsing.

To make applying it easy I'd sugges you fetrch everything needed by:

git fetch https://github.com/pipo/libvirt.git features-filter

Peter Krempa (15):
  qemu: Rename qemuDomainCmdlineDefPtr to qemuDomainXmlNsDefPtr
  qemu: Move qemuDomainXmlNsDef(Free) from qemu_conf.(ch)
  qemu: domain: Use virStringListFreeCount in qemuDomainXmlNsDefFree
  qemu: Extract parsing of qemu namespace arguments into separate
    function
  qemu: Extract parsing of qemu namespace env vars into separate
    function
  qemu: Refactor qemuDomainDefNamespaceParse
  qemu: domain: Split out commandline namespace data formatting
  conf: Add taint flag for custom hypervisor features
  qemu: Add support for controling qemu capabilities via the qemu XML
    namespace
  qemu: domain: Add support for modifying qemu capability list via qemu
    namespace
  tests: qemuxml2argv: Modernize and fork 'qemu-ns' test
  tests: qemuxml2argv: Test qemu namespace capability tweaking
  qemu: Remove unused var 'corestr' from virQEMUDriverConfigLoadFile
  qemu: conf: Add debug option to allow disabling qemu capabilities
