Hi All,

Am able to install successfully the OpenStack PackStack(Kilo) multinode(1 aio & 1compute node) setup using CentOS7 VMs. The contents of /etc/hosts on aio & compute node is given below,

10.1.64.132 aio132.onecloud aio132
10.1.64.142 compute142.onecloud compute142

Am working on the live VM migration but i faced difficulty with the hostnames.The issue observed here is when i check the nova services list, noticed the additional Hosts as aio132.novalocal and compute142.novalocal.(C:\fakepath\nova_services.jpeg).

The hypervisor list shows C:\fakepath\hypervisor_list.JPG

I dont understand why this kind of hosts are present..!! Sometimes am not able see these hosts C:\fakepath\nova_services_up.jpeg I need some inputs about to how to remove these hosts with .novalocal and left only with desired hostname aio132 & compute142. The hostnames with .novalocal are troublesome for me during live VM migration. Please help me to fix this..!!

Thanks

Hi,

check compute nodes hostname and configuration files searching for any incongruity between them.

If you need to remove compute nodes from nova service-list, use:

nova service-disable <hostname> >binary>
nova service-delete <ID>

Some python-novaclient don't have disable option, at least 2.17.0 from Ubuntu repository don't have it. Version 2.23.0 from RDO have it.

Regards

When troubleshooting this on my remote environment, i still remember following https://thornelabs.net/2014/08/03/del... and didn't work. The remote setup is unavailable for me now, once its available, will check and tell you soon..!!
