| remap_vbd_dev_prefix = sd | (StrOpt) Specify prefix to remap VBD dev to (ex. /dev/xvdb -> /dev/sdb) |
| running_timeout = 60 | (IntOpt) Number of seconds to wait for instance to go to running state |
| 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 |
| sr_base_path = /var/run/sr-mount | (StrOpt) Base path to the storage repository |
| sr_matching_filter = default-sr:true | (StrOpt) Filter for finding the SR to be used to install guest instances on. 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 |
| target_host = None | (StrOpt) The iSCSI Target Host |
| target_port = 3260 | (StrOpt) The iSCSI Target Port, default is port 3260 |
| torrent_base_url = None | (StrOpt) Base URL for torrent files. |
| torrent_download_stall_cutoff = 600 | (IntOpt) Number of seconds a download can remain at the same progress percentage w/o being considered a stall |
| torrent_images = none | (StrOpt) Whether or not to download images via Bit Torrent (all|some|none). |
| torrent_listen_port_end = 6891 | (IntOpt) End of port range to listen on |
| torrent_listen_port_start = 6881 | (IntOpt) Beginning of port range to listen on |
| torrent_max_last_accessed = 86400 | (IntOpt) Cached torrent files not accessed within this number of seconds can be reaped |
| torrent_max_seeder_processes_per_host = 1 | (IntOpt) Maximum number of seeder processes to run concurrently within a given dom0. (-1 = no limit) |
| torrent_seed_chance = 1.0 | (FloatOpt) Probability that peer will become a seeder. (1.0 = 100%) |
| torrent_seed_duration = 3600 | (IntOpt) Number of seconds after downloading an image via BitTorrent that it should be seeded for other peers. |
| 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. |
| use_join_force = True | (BoolOpt) To use for hosts with different CPUs |
| vhd_coalesce_max_attempts = 20 | (IntOpt) Max number of times to poll for VHD to coalesce. Used only if compute_driver=xenapi.XenAPIDriver |

| Configuration option = Default value | Description |
|---|---|
| [zookeeper] | |
| address = None | (StrOpt) The ZooKeeper addresses for servicegroup service in the format of host1:port,host2:port,host3:port |
| recv_timeout = 4000 | (IntOpt) The recv_timeout parameter for the zk session |
| sg_prefix = /servicegroups | (StrOpt) The prefix used in ZooKeeper to store ephemeral nodes |
| sg_retry_interval = 5 | (IntOpt) Number of seconds to wait until retrying to join the session |
