xm list虚拟机无状态

when executing "xm list" command, u may see this output below:

[root@spark ~]# xm li
Name                                        ID   Mem VCPUs      State   Time(s)
1-pv                                         1   256     1     ------      1.5
2-pv                                         2   256     1     ------      0.7

state line shows nothing, why?

"I don't know why it's not progressing, but it's perfectly possible to have a state of "nothing" - it happens when the system is neither running (e.g. there's no available CPU for it) and not blocked, paused, shutdown, crashed or dying. It's just not scheduled, and it's waiting for a CPU to become available."
