  • ​(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
