I'm trying to setup the xenapi environment through devstack to add support in ceilometer side. However, I always get followed error when I start the ./install_os_domU.sh: Starting VM... + xe vm-start uuid=a428f69e-d2ef-25df-58fe-c835fe1070a6 Error code: INVALID_SOURCE Error parameters: Unable to access a required file in the specified repository: http://archive.ubuntu.net/ubuntu/dists/oneiric/main/installer-amd64/current/images/netboot/xen/vmlinuz., , My system requires proxy, but I have set the http_proxy/https_proxy/ftp_proxy already. I also try to use wget to retrieve this file and it succeed. Can anyone give some hints on it? Thanks --jyh
