Hi, all We have some new requirements of preferences, I listed which of them I known, and think is useful as follows: 1) for the path of x509 certificate and keys of client The path of x509 certificate and keys of client is hard coded in remote driver. e.g. /* Defaults for PKI directory. */ # define LIBVIRT_PKI_DIR SYSCONFDIR "/pki" # define LIBVIRT_CACERT LIBVIRT_PKI_DIR "/CA/cacert.pem" # define LIBVIRT_CLIENTKEY LIBVIRT_PKI_DIR "/libvirt/private /clientkey.pem" # define LIBVIRT_CLIENTCERT LIBVIRT_PKI_DIR "/libvirt/clientcert.pem" 2) for default default driver and subdriver for disk image Another requirement of new preference is default driver and subdriver for disk images, currently we use "phy" for "driver" in virsh, and "raw" for "subdriver" in qemu driver by default if user doesn't specify them, it causes bugs, though we could say to user "you should use options --driver and --subdriver", but these two options are optional. IMHO, the best solution for those bugs is to provide new preferences. 3) for default NIC and storage type "Chris Phillips" raised up the requirement not long ago: http://www.redhat.com/archives/libvirt-users/2010-November/msg00033.html ==================== Should we add these new preferences(if they are really neccessary) in qemu.conf? or create new config file, e.g. The approch Justin raised up an approch before: http://www.redhat.com/archives/libvir-list/2010-November/msg00651.html Though for Justin's approch, IMHO we'd better also to provide a default config file, e.g. "/etc/libvirt/client.conf".
