2016-07-20 02:50:26 -0500 asked a question Difference between partitios image and whole disk image

Hi stackers:

There are two types of image for ironic node deployment: partition and whole disk.

What is the difference between them? Thanks.

Hi stackers.

I got the centos7_minimal.iso from http://mirrors.163.com/centos/7.0.1406/isos/x86_64/CentOS-7.0-1406-x86_64-Minimal.iso.

nova version: 2014.1

use flavor below:

Launch one instance with flavor and image above.

#nova boot --flavor c9425a87-2453-4af5-9011-7eb2bd6f3653 --image centos7-mini-iso instance-boo-from-iso

instance was launched successfully. But when I install cent os with console, got:

Hi stackers, I want to boot one instance from centos7_minimal_iso. But got "warning: /dev/root does not exist." Can anyone know why? Thanks a lot!

"hostname" for instance, "host" for the name of computing node.

Change to "neutron:neutron" with chown?

2015-02-09 17:02:08 -0500 answered a question Permission denied in dhcp agent

hi, please check if sudo config for neutron exists, like "/etc/sudoers.d/neutron" on rhel7.

hi stackers, I use stable icehouse branch. For instances table in nova-db, there are hostname and display_name. Check the source and find hostname same as display_name. Can anyone explain the differents between them? Thanks~

Please check the nova rootwrap filters if blockdev --getsize64 support. 1. Check /etc/nova/nova-rootwrap.conf to find the filter file. Like /usr/share/nova/rootwrap/compute.filters 2. Check the filter file if has the command. Wish help~
