Unable to launch Centos/CirrOS instance

[Ravi Tandon]

Whenever I try to launch an instance (Centos or CirrOS), it fails with an Error

fault | {"message": "Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 1f2bdbed-4a34-4ca3-93ed-5a8e0245609e.", "code": 500, "details": " File \"/usr/lib/python2.7/site-packages/nova/conductor/manager.py\", line 580, in build_instances

Please help to resolve the issue.

[p.cipriano (ctpeter)]

Same with me.

Error: Failed to perform requested operation on instance "test", the instance has an error status: Please try again later [Error: Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 5bc74b2c-03b5-4be5-96dc-b60941b64dce.].

Release: "queens"
OS : CENTOS
Install_type : source

[Matt Riedemann (mriedem)]

There are likely failures in the nova-compute and/or nova-conductor logs, you would need to dig through those logs (or attach them) to help diagnose the reason for the build failures.

[Thaps (thaps)]

I am facing same error, have resolved the issue? if yes let me know.

[Ravi Tandon (ravi-100)]

Not yet.

But I believe this error is related to resources available on the server.
I am awaiting my new server with 40 cores, earlier I was trying on a VM
with just 8 cores
and 16 GB RAM.

Whats the configuration of the server on which you have installed
openstack?

[Jim Ntosas (ntosas)]

Hello Ravi,

If you can confirm that you have enough resources to allocate your instance (cirros only need some MB of RAM), then the issue comes from networking (neutron) and not from nova itself.

Trace neutron logs for "PortBindingFailed" to check my assumption.

[Prankul Mahajan (prankul)]

The same thing happened with me .
But upon launching the instance multiple times the issue disappeared.
I think this is not a bug but a server issue

[Dmitry Snitko (win-di)]

Hello,
I faced the same issue when, by mistake, I tried to launch an instance with public network attached only instead of local network (in my case external net had no DHCP enabled).
Thanks Jim Ntosas for the useful insight about nova vs neutron issue in #5.

[Peter (zpeterg)]

I had the same problem, and Dmitry's problem fixed it - I was starting and instance into public network.
