Well, this procedure is missing the obvious errors, but the result is still not entirely satisfying:

Ran the following command:
ploop umount /storage/plooptest/test1/DiskDescriptor.xml -m /storage/plooptest/mount/test1


Output:
Unmounting file system at /storage/plooptest/mount/test1
Unmounting device /dev/ploop43259


but:
mount

/dev/cciss/c0d0p3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/cciss/c0d0p1 on /boot type ext4 (rw)
/dev/cciss/c0d1p1 on /storage type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/storage/plooptest/test1/DiskDescriptor.xml on /storage/plooptest/mount/test1 type ploop (rw)


while:
cat /proc/mounts

proc /proc proc rw,relatime 0 0

As you can see "mount" still thinks, that the device is mounted, while it is actually unmounted.

Thank you for your help so far. I can work with this solution for now by ignoring /etc/mtab and /bin/mount respectively.
