Yes I really need it. I have to create a virtual network editor for
my diploma project. So I have found many virtual solutions but the
bestest for our project is OpenVZ. Unfortunatly, OpenVZ don't offer
the copy on write with his solution, after many tests, I have found a
solution based on LVM.
The main idea is to have a Virtual Private Server Core and lot of
Virtual Private Server who are a snapshot of the Virtual Server Core.
Now the problem is the limitation of VLM, I need more than 32 servers
(32 snapshots). Will this limitation incresed in futur futur released
of LVM? Or can we broke this limitation?
Have you a solution, it's relly urgent for me...
Thanks you

I don't understand the error..
I'm not a native french speaker (hint!) but I assume you run out of
memory.
Yes there are limitations to the number of snapshots. For every single
snapshot we have to allocate memory for copying the chunks to the
exception
store.
Do you really need that many snapshots at the same time?
