I can't run instance,

when execute "euca-run-instances ami-sfipmfmy --kernel ami-ko6e7utb --ramdisk ami-ujs7u9y0 -k mykey"

the status is always like this:

[root@localhost dowmload]# euca-describe-instances RESERVATION r-bevirrog PRO3 default INSTANCE i-00000002 ami-sfipmfmy scheduling mykey (PRO3, None) 0 m1.small 2011-03-01 05:08:37.620438 unknown zone

and in "nova-scheduler" occurs errors like this:

[root@localhost dowmload]# nova-scheduler 2011-03-01 13:03:43,121 AUDIT nova.root [-] Starting scheduler node (version 2011.1-workspace:tarmac-20110202111800-10sib5zxlu8xluca) 2011-03-01 13:08:39,242 ERROR nova.root [-] Exception during message handling (nova.root): TRACE: Traceback (most recent call last): (nova.root): TRACE: File "/usr/lib/python2.6/site-packages/nova-2011.1-py2.6.egg/nova/rpc.py", line 192, in receive (nova.root): TRACE: rval = node_func(context=ctxt, *node_args) (nova.root): TRACE: File "/usr/lib/python2.6/site-packages/nova-2011.1-py2.6.egg/nova/scheduler/manager.py", line 63, in _schedule (nova.root): TRACE: host = self.driver.schedule(elevated, topic, *args, *kwargs) (nova.root): TRACE: File "/usr/lib/python2.6/site-packages/nova-2011.1-py2.6.egg/nova/scheduler/chance.py", line 37, in schedule (nova.root): TRACE: raise driver.NoValidHost(_("No hosts found")) (nova.root): TRACE: NoValidHost: No hosts found (nova.root): TRACE:

Please post your output of "nova-manage service list". If I correctly remember this means that there are no nova-compute nodes availabe where the nova-scheduler can place a new instance.

Janson, this seems to be a dup of your colleagues problem? https://answers.launchpad.net/nova/+question/147177 (https://answers.launchpad.net/nova/+q...)

Can we close this question and keep the focus in that thread?
