i tried this method this worked for me in case of listing partitions

[root at EQkvm0101 ~]# guestfish -- add /dev/null : config -set
drive.hd0.file=rbd:ssd-clonetest-rule5/fullclone.img : run : list-partitions

/dev/sda1

/dev/sda2

[root at EQkvm0101 ~]#



thankyou so much for the reply



Also i can't use the newest version of libguestfs as im on a production
system and i could not use the newest version due to some limitations.

Also the new version is not available in repo.



Im getting antother problem :

while running these commands im getting error :
guestfish -- add /dev/null : config -set
drive.hd0.file=rbd:ssd-clonetest-rule5/ubuntu-12.04--1.raw.img : run :
inspect-os
/dev/ubuntu-1204-vg/root
[root at EQkvm0101 ~]# guestfish -- add /dev/null : config -set
drive.hd0.file=rbd:ssd-clonetest-rule5/ubuntu-12.04--1.raw.img :
 inspect-get-distro /dev/ubuntu-1204-vg/root
libguestfs: error: no inspection data: call guestfs_inspect_os first
