Did you also read his update on that post, linking to

I'd start with running "xm list" and see if your domU is actually
running or not. After that, do something like

netstat -anp | egrep "(:59)(.+)(LISTEN)"

to see if there's any process listening on port 5900+. If a domU was
started and it has a vnc GUI, there should be some qemu-dm process
shown there.

Where does loop0 come from? If you're using disk/partition as domU
storage you can simply specify the block device (e.g. /dev/sdb,
/dev/sda4, etc.). If you're using file you can directly use tap:aio.

I'm guessing you specified the wrong disk and domU didn't start at all.
