╰───┴─────────────┴─────────┴────────┴──────┴────────────┴────────────┴──────┴───────────╯The * marks the host currently selected as active for this context.
GPUS shows allocated/capacity with the GPU model in parentheses when the host
advertises one. A host with no GPU capacity renders -, so a CPU-only fleet
stays readable. GPU capacity is only probed and reported on qemu hosts, a
firecracker host always shows -. For per-device detail and MIG instance
pools, see fuse host get and
fuse host metrics.
LAST SEEN is stamped at registration and never refreshed, it is not a liveness signal and the scheduler never consults it. Judge reachability from the STATE column and the host agent’s own health endpoint instead.
Select
fuse host [id]With an ID, validates the host exists (a GET against it) and, if so, sets it
as the active host for the current context, persisted to the config file. With
no ID, prints the current selection instead of changing it.
fuse host prod-east-1
# selected host "prod-east-1"
fuse host
# active host: prod-east-1Subcommands (register, get, cordon, uncordon, remove, metrics) take
precedence over selection, fuse host register ... runs the register
subcommand, not a selection attempt on a host literally named register. They
are registered under the plural fuse hosts as well, so neither name is a dead
end.
