This introduces new attribute wrpolicy with only supported value as immediate. This will be an optional attribute with no defaults. This helps specify whether to skip the host page cache.
When wrpolicy is specified, meaning when wrpolicy=immediate a writeback is explicitly initiated for the dirty pages in the host page cache as part of the guest file write operation.
Usage: <filesystem type='mount' accessmode='passthrough'> <driver type='path' wrpolicy='immediate'/> <source dir='/export/to/guest'/> <target dir='mount_tag'/> </filesystem>
Currently this only works with type='mount' for the QEMU/KVM driver.

Please add a new pair of test files to tests/qemuxml2argvdata (both .xml and .args file) to validate the RNG, as well as listing that file name in tests/qemuxml2argvtest.c to validate the qemu command line generation (I find it easiest to start from an existing similar .xml file, and just add in the new attribute). -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
