Open Stack

Ritesh,

 

I will try your method.

 

In the past,when I boot a new instance from a ubuntu image,it works ok.
Centos and windows image was created by me according docs.openstack.org
information,and every time when a new instance created from centos and
windows,system always told me "Libvirt: QEMU error: Domain not found: no
domain with matching name,...", but finally, the instance works well.

 

So, I am not clear about the reason.

 

Thanks.

 

Romi

domain not found: no domain with matching name

 

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
