Hello everybody!

There are multiple possible reasons, you should start finding out what is the module generating the error. Run:

#nova show [vm name]

and see what type of error you get (networking, scheduling, so on...) after that, look at the log of that specific module and see if you can spot any exception or error message.

see the nova-compute log which the instance is schedulerd to

Hi maleck!

There are information that I follow you. Maybe scheduler problem and I look at nova-scheduler.log> I saw "Failed to schedule_run_instance: No valid host was found. Is the appropriate service running?", but I run command "nova-manage service list" nova-scheduler has status :-)

Hi,

Nova-scheduler is working well and you error, in fact, makes sense:

nova-compute ubuntu nova enabled XXX 2012-08-16 11:51:06

As you can see from the line above, Nova compute service is not running property. For this reason, the scheduler is unable to find a suited host for building the requested VM and raise an error (Because, roughly, only host with nova-compute running in it are the ones in which the VMs will be spawned).

Start nova-compute with the following:

service nova-compute start

then check the service status to see if it crashes at some point. If it does not, then you should probabli see ":-)" near nova-compute service using "nova-manage service list".

Otherwise, if the nova-compute service crashes (and it will most likely happen) you should find out why in happens. To do so read nova-compute logs, or else, run it with "strace -f nova-compute", when it stops read the debug informations and paste them here.
