[libvirt] [PATCH 0/6] qemu: Add support for 'write-cache' disk frontend argument (blockdev-add saga)

[Peter Krempa]

'write-cache' is one of the booleans the 'cache' attribute of -drive
translates to. Since we are getting rid of -drive this needs to be
implemented in a different way.

Peter Krempa (6):
  tests: utils: Allow parsing test capability file without virCaps
  tests: qemuxm2argv: Add infrastructure for testing with real qemuCaps
  qemu: domain: Add helper for translating disk cachemode to qemu flags
  qemu: caps: Add capability for 'write-cache' parameter of disk
    frontends
  qemu: Format 'write-cache' parameter for disk frontends
  tests: qemuxml2argv: Test formatting of 'write-cache' parameter
