Interesting, can you even login, and the system still works?
Then Xen is saving the file from being deleted totally until the vm is
shut down. After that, it will probably free the open file, and it
will be gone.

So don't stop the vm, and do a full rsync backup ASAP.

This is a generic linux problem and has nothing to do with Xen.

I think, if you once stop the vm and have not done an rsaync backup as
said above, you have  not much chances, but at very first, you should
stop the machine completely and not use the harddisk where the lost
image resided.

Go to linux recovery mailing lists and read about that.

As far as I know, when you don't use special techniques in advance,
(there is some libraray that makes rm not really delete stuff, AFAIK,
and for sure we all have backups, at least _after_ we lost important
data the first time, right?!), it's absolitely not easy to recover
lost files.
