This may sound odd, but have you run the save command a second time
after the first time never returned? I have a similar configuration as
you and I just ran xm save command. The first time, it just sat there
and didn't return. I exited it and ran the command again and it worked. 

I'm still figuring out why. But it worked the second time I ran the xm
save command.

I followed up the save with "xm restore" and that worked.

Thanks,

Dan
