The manager runs with a read-only root filesystem and the seed ISO
writer stages files in a temp directory, so the first in-cluster Create
failed with "creating iso writer: read-only file system". Mount a 64 MiB
emptyDir on /tmp.
That error is classified ErrPermanent by writeSeed, yet hostPool.call
treated every non-libvirt error as a transport failure and dropped the
cached SSH connection, redialling on each retry. Errors that already
carry a provider sentinel are local verdicts, not evidence about the
link; leave the connection alone for those.
