[libvirt] How to override TLS client cert and key locations used for migration?

Hi guys, Does anyone know if it's possible to override the default locations used for the TLS client certificate and it's private key, as used in migration? We have overrides in libvirtd.conf for the server cert and its private key, but I'm not seeing anything for the corresponding client pieces. The remote driver appears hard coded to use the default locations only: src/remote/remote_driver.c src/remote/remote_driver.h Any ideas? Regards and best wishes, Justin Clift
