To use the Local Storage in default XenServer/XCP installations set this flag to other-config:i18n-key=local-storage. To select an SR with a different matching criteria, you could set it to other-config:my_favorite_sr=true. On the other hand, to fall back on the Default SR, as displayed by XenCenter, set this flag to: default-sr:true

xenapi_agent_path=usr/sbin/xe-update-networking	(StrOpt) Specifies the path in which the xenapi guest agent should be located. If the agent is present, network configuration is not injected into the image. Used if compute_driver=xenapi.XenAPIDriver and flat_injected=True
xenapi_check_host=True	(BoolOpt) Ensure compute service is running on host XenAPI connects to.
xenapi_connection_concurrent=5	(IntOpt) Maximum number of concurrent XenAPI connections. Used only if compute_driver=xenapi.XenAPIDriver
xenapi_connection_password=None	(StrOpt) Password for connection to XenServer/Xen Cloud Platform. Used only if compute_driver=xenapi.XenAPIDriver
xenapi_connection_url=None	(StrOpt) URL for connection to XenServer/Xen Cloud Platform. A special value of unix://local can be used to connect to the local unix socket. Required if compute_driver=xenapi.XenAPIDriver
xenapi_connection_username=root	(StrOpt) Username for connection to XenServer/Xen Cloud Platform. Used only if compute_driver=xenapi.XenAPIDriver
xenapi_disable_agent=False	(BoolOpt) Disables the use of the XenAPI agent in any image regardless of what image properties are present.
xenapi_image_compression_level=None	(IntOpt) Compression level for images, e.g., 9 for gzip -9. Range is 1-9, 9 being most compressed but most CPU intensive on dom0.
xenapi_image_upload_handler=nova.virt.xenapi.image.glance.GlanceStore	(StrOpt) Dom0 plugin driver used to handle image uploads.
xenapi_ipxe_boot_menu_url=None	(StrOpt) URL to the iPXE boot menu

xenapi_ovs_integration_bridge=xapi1	(StrOpt) Name of Integration Bridge used by Open vSwitch
xenapi_remap_vbd_dev=False	(BoolOpt) Used to enable the remapping of VBD dev (Works around an issue in Ubuntu Maverick)
xenapi_remap_vbd_dev_prefix=sd	(StrOpt) Specify prefix to remap VBD dev to (ex. /dev/xvdb -> /dev/sdb)
xenapi_running_timeout=60	(IntOpt) number of seconds to wait for instance to go to running state
xenapi_sparse_copy=True	(BoolOpt) Whether to use sparse_copy for copying data on a resize down (False will use standard dd). This speeds up resizes down considerably since large runs of zeros won't have to be rsynced
xenapi_sr_base_path=/var/run/sr-mount	(StrOpt) Base path to the storage repository
xenapi_torrent_base_url=None	(StrOpt) Base URL for torrent files.
xenapi_torrent_download_stall_cutoff=600	(IntOpt) Number of seconds a download can remain at the same progress percentage w/o being considered a stall
xenapi_torrent_images=none	(StrOpt) Whether or not to download images via Bit Torrent (all|some|none).
xenapi_torrent_listen_port_end=6891	(IntOpt) End of port range to listen on
xenapi_torrent_listen_port_start=6881	(IntOpt) Beginning of port range to listen on

xenapi_use_agent_default=False	(BoolOpt) Determines if the xenapi agent should be used when the image used does not contain a hint to declare if the agent is present or not. The hint is a glance property "xenapi_use_agent" that has the value "true" or "false". Note that waiting for the agent when it is not present will significantly increase server boot times.
xenapi_vhd_coalesce_max_attempts=5	(IntOpt) Max number of times to poll for VHD to coalesce. Used only if compute_driver=xenapi.XenAPIDriver
xenapi_vhd_coalesce_poll_interval=5.0	(FloatOpt) The interval used for polling of coalescing vhds. Used only if compute_driver=xenapi.XenAPIDriver
xenapi_vif_driver=nova.virt.xenapi.vif.XenAPIBridgeDriver	(StrOpt) The XenAPI VIF driver using XenServer Network APIs.
