The qemu ssh block device is now up to version 7 … although sadly not upstream yet.
Nevertheless by applying this patch to libguestfs you can use libguestfs to access remote disks over ssh:
$ export LIBGUESTFS_QEMU=~/d/qemu/qemu.wrapper $ export LIBGUESTFS_BACKEND=direct $ ./run ./fish/guestfish Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems. Type: 'help' for help on commands 'man' to read the manual 'quit' to quit the shell ><fs> add /tmp/f17x64.img readonly:true format:raw \ protocol:ssh server:onuma ><fs> run 100% ⟦▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒⟧ 00:00 ><fs> inspect-os /dev/vg_f17x64/lv_root ><fs> inspect-get-product-name /dev/vg_f17x64/lv_root Fedora release 17 (Beefy Miracle) ><fs> list-filesystems /dev/sda1: ext4 /dev/vg_f17x64/lv_root: ext4 /dev/vg_f17x64/lv_swap: swap ><fs> mount /dev/vg_f17x64/lv_root / ><fs> cat /etc/redhat-release Fedora release 17 (Beefy Miracle)
Everything just works as if this were a local disk.
There are a couple of minor caveats (the major caveat being none of this is upstream): Firstly you have to have ssh-agent set up. Secondly the remote host must be in your
known_hosts file (if not, do
ssh remotehost first to add it).
