It definitely should work, although I don't know if anyone has tried using the address explicitly (rather than a hostname which resolves to an AAAA record). > For example: > > guestfish --format=raw --ro -a > rbd://[fd00::cefc:1]:6789/images/CentOS-7-x86_64-GenericCloud-1901 > > Does not work citing the following: The important lines are these. Firstly guestfish parses the URL into an actual libguestfs API call, which looks fine to me: > libguestfs: trace: add_drive > "images/CentOS-7-x86_64-GenericCloud-1901" "readonly:true" > "format:raw" "protocol:rbd" "server:tcp:[fd00::cefc:1]:6789" This is probably where it goes wrong: > "/tmp/libguestfs3pGMi6/overlay1.qcow2" "qcow2" -1 "backingfile:rbd:images/CentOS-7-x86_64-GenericCloud-1901:mon_host=[fd00::cefc:1]\:6789:auth_supported=none" > "backingformat:raw" > libguestfs: command: run: \ -o backing_file=rbd:images/CentOS-7-x86_64-GenericCloud-1901:mon_host=[fd00::cefc:1]\:6789:auth_supported=none,backing_fmt=raw > libguestfs: command: run: \ /tmp/libguestfs3pGMi6/overlay1.qcow2 > qemu-img: /tmp/libguestfs3pGMi6/overlay1.qcow2: invalid conf option > :cefc:1]:6789:auth_supported: No such file or directory > Could not open backing image to determine size. The code in libguestfs is supposed to turn the guestfs_add_drive ‘servers’ parameter into a Ceph URL for qemu: https://github.com/libguestfs/libguestfs/blob/f79129b8dc92470e3a5597daf53... and I suppose this is being done wrong somehow (I don't have a Ceph server to test). At a guess I would say that it seems as if ':' characters must be quoted somehow (backslash?) because they are also used to separate the address and port number. Rich.
