      Unable to open connection to hypervisor URI 'xen':


      virsh: error: failed to connect to the hypervisor

      After debugging a bit the problem looks pretty trivial - libvirt tries to access


      The default config of xend as it is currently in the repostitory seems to have the config in /etc/xen/xend-config.sxp default to no and commented out:

       #(xend-unix-server no)

      change this to

       (xend-unix-server yes)
      • (xend-unix-path /var/lib/xend/xend-socket) のコメントアウトも必要
    • (xend-http-server yes) だけでも良い模様
