Is there any known issue on saving a domain which is in pause state?
Xen hangs whenever I try to save (by means of xm save command) the state of a machine which has been paused (by means of xm pause command). I have been looking at the log files etc but I am not able to spot the problem. BTW, xm save works prefectly fine if the domain is running or block. The problem is when the domain is in pause.
 
I am ataching below the xend.log file in case it helps.
 
Any help is highly appreciated!
