Hi. Thanks to help of this mailing list (especially Jim Fehlig), I have finished setup of libvirt. However, there is something weird. It is that I installed libvirt on 5 servers but the default connection of one of them is 'qemu:///' even if those of the others are all 'xen:///'.

I searched how to change it but, I only found a bypass adding " LIBVIRT_DEFAULT_URI='xen:///' " in my .bashrc file. Currently, value of the variable (LIBVIRT_DEFAULT_URI) is set to 'qemu:///'. Since the bypass makes the virtualization type of the server visible 'qemu' to the open stack, I have to change libvirt configuration. I also checked some configure files under '/etc/libvirt', such as libvirt.conf, libvirtd.conf and libxl.conf. But I have no idea, how and what to change. Please give me some advise. It will be a big help for me.

Which, as you can see above, is exactly what OP is already doing and what they're looking for an alternative to ;)

Also note that, at least as far as I understand, they want to make sure the xen:/// default URI is picked up by an high-level management application (in this case OpenStack), which suggests the new default should be set globally rather than per-user, which is the reason why
