I've learned few facts about XENserver in last couple of days.
e.g. On XENserver, when you take snapshot, XENserver will create a 2 VDI
(Base VDI+place holder for snapshot) file on same primary storage (SR in
XENserver terms) as disk is. You will offcouse have a vhd file saved on
seconday storage. Here is funny part, when you delete snapshot from
cloudstack, XENserver won't do anything to remove these additionally crated
VDI
Plus XENserver will copy and crate template for VR on each individual host
on its SR. this space is not visible in cloud stack.
Check things from SR level on XENcenter. You can delete any template
entries etc.(BE CAREFUL)
Also try digging in with command line
1) xe vdi-list sr-name-label=<LUNNAME>
params=uuid,name-label,name-description,physical-utilisation,virtual-size,is-a-snapshot,sm-config
this will give you all VDIs present on that storage (give attention to
is-snapshot=true ones)
2) lvs
this will give you summary of all the LVs on the SRs. Note the last marked
in this example (Attr=-ri---) is snapshot.

I have cases where I've to remove some entries manually just to gain free
space. for me its ACS 4.4.2 and XENserver 6.2
Good luck with your troubleshooting
