    • (XenPPC) virt-manager/virsh connection errors - fixed

      virt-manager:

      Unable to open connection to hypervisor URI 'xen':

      virtsh:

      virsh: error: failed to connect to the hypervisor

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

       /var/lib/xend/xend-socket
      

      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
      • Dom-0のstatusが見られるようになる
