Not sure if this possible, but I have a KVM guest running Solaris 10 with the OS on ZFS and I am trying to use libguestfs/guestfish/guestmount to get to the VM. I am running Red Hat EL 5.4 with EPEL rpms as required. The VM is on a LV and it boots fine, but I can't seem to get the syntax correct to get libguestfs to deal with it. Guestmount seemed like the best option because it supports FUSE modules. I have fuse installed and zfs-fuse and I can create ZFS filesystems on the physical host machine. Just really not sure how to make libguestfs deal with it. I have tried mounting the pool and the underlying virtual disk device with no success. # guestmount -o modules=zfs -a /dev/kvmVG00/sol10u6 -m newpool/ROOT/s10up-08 --ro /mnt libguestfs: error: mount_options: mount_options_stub: newpool/ROOT/s10up-08: expecting a device name # guestmount -o modules=zfs -a /dev/kvmVG00/sol10u6 -m /dev/dsk/c0d0s0 --ro /mnt libguestfs: error: mount_options: mount_options_stub: /dev/dsk/c0d0s0: No such file or directory # guestmount -o modules=zfs -a /dev/kvmVG00/sol10u6 -m /dev/dsk/c0t0d0s0 --ro /mnt libguestfs: error: mount_options: mount_options_stub: /dev/dsk/c0t0d0s0: No such file or directory # rpm -qa | grep fuse zfs-fuse-0.6.0-6.el5 fuse-2.7.4-8.el5 fuse-libs-2.7.4-8.el5 # rpm -qa | grep guest libguestfs-1.0.85-1.el5.9 guestfish-1.0.85-1.el5.9 perl-libguestfs-1.0.85-1.el5.9 libguestfs-tools-1.0.85-1.el5.9 libguestfs-mount-1.0.85-1.el5.9 libguestfs-devel-1.0.85-1.el5.9 Any help MUCH appreciated.
