Looks like your VM uses a raw file as virtual hard disk. RAW does not 
support snapshots, hence the VM has to be suspended.

Well - you have to add a LVM volume group as storage und use this as 
storage for your VM. Have a look at

In theory qcow2 image files should support snapshot as well, but I have 
never used that so far.
