so check_running is also called with the name
The output of xm domid name for a running domain is the ID of
the domain and None for a known, but not runing domain. The return
code for both cases is 0. So the function always returns 0. With xen
3 and no xend, this code was correct.

With xm and 4.1:
| # xen domid test; echo $?
| Error: Domain 'test' does not exist.
| 3
Does domain test exists on your host?
'exist' or 'known' means known to Xend domain management.
Here is my output with a known domain, running and not running:
root# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 1331 4 r-376.8
elearn 4 2 -b 4.8
pulli 1 1600 2 -b 42.2
root# xm shutdown elearn
root# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 1331 4 r-379.0
elearn 2 5.4
pulli 1 1600 2 -b 42.2
root# xm domid elearn
None
0
root# sleep 300; xm domid elearn ; echo $?
None
0
root# xm domid mushroom ; echo $?
Error: Domain 'mushroom' does not exist.
3
root# xm start elearn
root# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 1331 4 r-383.5
elearn 5 2 -b 4.8
pulli 1 1600 2 -b 42.2
root# xm domid elearn ; echo $?
5
0
So with a not known domain, 'mushroom' in my case, i got the same output
as you. But with an known domain, the return code of xm domid dont
indicates the running state.
