Have tested and raised two issues
One is on migration:
Migration from cap-ibs=workaround -> cap-ibs=broken crashes guest rather to fail the migration gracefully.
expected the source guest continue to be in running state after the migration failure, but the guest crashes at destination and leaves the guest in source in paused state.
Raised Bug 180734 for the same.

Another is on usability of the hardware assisted flush(cap-ccf-assist=on), right now it has be set explicity in qemu-cmdline though we have HW support, but other layers like libvirt etc will not know about it. So it is not possible for user to set the capability though underlying HW is capable.
Raised Bug 180735 for the same.
