[Users] VM has paused due to unknown storage error

[Yeela Kaplan]

It seems that your guest file system is corrupted.
The dd approach won't help cause this is a virtual disk,
you need to fix the virtual disk inside the lv, that's why any operations on the lv won't help. 
You can try shutting down the vm (not paused, but literally down) and add the guest vm disk as
a second disk to another vm.
In the second vm try to run fsck on the disk and see if it helps.
In any case before trying to manipulate the disk image please save a backup!!!
let me know how it goes...
