We have setup OpenStack using conjure-up on a (Ubuntu LTS server 16.04.3) single machine. All are services are up and running, and successfully I am able to upload images to the glance.

We wanted to save these glance images created by "glance image-create" in remote machine which have nfs server. So we have configured glance-api.conf file as below.

My glance-api.conf looks like this:

[glance_store]
filesystem_store_datadir = /var/lib/glance/images
default_store = file

And in glance controller node, I have mounted

remote machine Ip/home/glance/images/ in this directory path /var/lib/glance/images

and have mentioned the same mounted directory path inside the glance-api.conf file.

I have created the two sample private network with some ip (192.168.1.0 and 10.221.50.0) but have not created a public network as at this moment I don't want to access this VM instance from outside.

When I am trying to launch the instance from dashboard UI as well as through CLI, I am getting below error.

Error: Failed to perform requested operation on instance "Ubuntu_Hawkbit", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].

Note: I have tried by associating Instance with different private network ,thinking that it may be network IP address issue but facing the same error.

When I check /var/log/nova/nova-compute.log logs, I see below error.

  • I would suggest you copy the error message and ask the question in the nova IRC channel (#openstack-nova at the freenode). `No valid host was found` seems like a `nova` issue to me rather than `glance.` – Lucas H. Xu Nov 21 '17 at 16:33
  • Is 10.206.193.159 the right IP address for the glance service? Also, you can check if glance is listening on that IP or not by doing: "netstat -tulpn | grep 9292" and ensuring that it is listening on *:9292 instead of just local host. Also, copy paste the glance related lines from nova.conf. – Praveen Yalagandula Nov 21 '17 at 19:43
  • @PraveenYalagandula, Yes 10.206.193.159 is the IP of glance service node.And glance is listening on 9292. Please find below details inside glance node. – RESHMA PAWAR Nov 22 '17 at 05:04
