[libvirt-users] direct local access to Xen without libvirtd

Hi all. I'm just new to libvirt. Looking page here http://libvirt.org/drvxen.html , there are examples of connection URIs to Xen. xen:/// (local access, direct) xen+unix:/// (local access, via daemon) xen://example.com/ (remote access, TLS/x509) xen+tcp://example.com/ (remote access, SASl/Kerberos) xen+ssh://root@example.com/ (remote access, SSH tunnelled) I thought the first example 'xen:///' would not need libvirtd, because the second line said 'via daemon'. But my C code using URI above prompts 'Failed to connect socket' error. So it seems that running libvirtd is mandatory. Is this right? Thanks for your reply in advance. Regards, Jungnam Lee
