[Xen-devel] [PATCH] Improve xm uptime command for inactive managed domains

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When I tried xm uptime command to a inactive managed domain, I saw 
the following error messages. 
At first, I tried xm uptime command to the inactive managed domain 
only.  I thought that the error message is adequate because the 
domain is inactive. 
Next, I tried xm uptime command to both the inactive managed domain 
and a active domain.  The uptime of the active domain was shown by 
xm uptime command, but the uptime of the inactive managed domain 
was not shown by xm uptime command.  I felt sad because xm uptime 
command caused error halfway. 

# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   747     2     r-----     63.7
vm1                                          1   256     2     r-----    209.5
vm2                                              128     1                 0.0
# xm uptime vm2
Name                                ID Uptime 
Error: Invalid argument.
Usage: xm uptime [-s] <Domain>

Print uptime for a domain.
# xm uptime vm1 vm2
Name                                ID Uptime 
vm1                                  1  0:04:00
Error: Invalid argument.
Usage: xm uptime [-s] <Domain>

Print uptime for a domain.

This patch improves xm uptime command for inactive managed domains. 
xm uptime command always shows 0:00:00 in uptime if domain is 
inactive. 

# xm uptime vm2
Name                                ID Uptime 
vm2                                     0:00:00
# xm uptime vm1 vm2
Name                                ID Uptime 
vm1                                  1  0:05:50
vm2                                     0:00:00
