Open Stack

Razique,

 

Thank you very much!

 

Here is the paste:

http://paste.openstack.org/show/20938/

 

this config was fine at the first testing system.

 

Current problem occurred at my second testing system, and at before I
created raw format image and convert to qcow2.

 

I am going to recreate image directly on qcow2 format,are just in
processing,



 

Is there anything should be cared with image? It looks like related with the
glance image,I guess.

 

Romi

Hey I just wanted to see if the domain was still declared within virsh
database

in case you can also go to your instances directory and un a $ virsh define
$instance-name/domain.xml

Can you post your nova.conf please ?

Hi Razique,

 

Is there anything need to have a deeper look?

Virsh list looks like well,same as the instance I created through nova boot.

Hello romi,

    Image got into a stuck state , only solution is to hack your database
for this particular instance and mark it as deleted, den restart nova-*
service, it would start working.

Hi,

 

I’ve installed essex and when I reboot one of the nova-compute node and next
when I start nova-compute service again,the system promote:

Libvirt: QEMU error: Domain not found: no domain with matching name
‘instance-0000000a’

 

Then I found:  

#ls /var/lib/nova/instances

_base instance-0000000a instance-0000000b instance-0000000c

#ls /etc/libvirt/qemu

instance-0000000b.xml instance-0000000c.xml Network

 

So:

/var/lib/nova/instances/instance-0000000a# virsh define libvirt.xml

Domain instance-0000000a defined from libvirt.xml

And:

#ls /etc/libvirt/qemu

Instance-0000000a.xml instance-0000000b.xml instance-0000000c.xml network

 

Then I restart: nova-compute &, and nova-compute could normally started.

I did not understand why reboot compute node,and usually the first
instance’s xml file was deleted and nova-compute will terminate.

 

By the way, when I create a new instance, the first line in the log also is
: Libvirt: QEMU error: Domain not found: no domain with matching name
‘instance-0000000a’

 

Anyone who had met such a problem and why?

 

Regards,

 

romi
