Xen users - May 2009 - Why my DomU OS'' State is always blocked? Thank you very much!!

Hi, all


When I type "xm list" command, It''s always display State is
Blocked.

During OS boot, State is Running, a few seconds later, State changes into
Blocked and always Blocked.

Why??? 


linux-jx4z:/ # xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  1317     2     r-----     75.5
Fedora5                                      1   200     1     -b----      6.9
centos.5-2                                   3   500     1     -b----      2.0


Thank you very much!

I think it is the same reason why the ps command shows only one
''R'' and
that too the ps command itself

when the xen is querying the machines, the dom0 will be the only scheduled 
one and others will be blocked. So, i think almost always only Domain-0 
will show ''r''

Others, correct me if i am mis-understanding this.

Hi,
Try running some programs or scripts on the guests and check the status
again. Whenever the guest is idle or when it is awaiting user input, the
status shows blocked. It does not mean the VM is blocked. Are you able to
login to the guest? There is some problem if xm console '' vm-id
'' does not
allow you access into the guest. Try executing xenmon.py which will give you
an insight into how much % of CPU is allocated for all the domains. You will
be able to see that the CPU is idle most of the times. That is the reason
why it shows blocked state. Hope I answered your question.


Regards
Ananth
