I want to list all the openstack VMs with projects name, powerstatus, ipaddress. The following command will shows all the VMs but it shows with tenant ID but I want to list with tenant name.

Any other command or python script to list all openstack setup VMs with tenant name?

I have added 3 additional compute nodes on our controller node. after that when I create a new virtual machine it adds 3 nic for the VM.

Where are the settings to disable this configuration and add only one nic when I create a VM?

2016-11-23 06:18:37 -0500 回答问题 instance hostname not getting resolved locally ?

I have the same issue. It resolved only after the dnsmasq service restart.

Is there any way to resolve it without service restart ?

I used the internal dns dnsmasq but not external "Designate".

2016-05-03 07:23:07 -0500 问了问题 Reverse DNS Record setup with neutron network

I am unable to configure reverse DNS record setup with neutron network. dnsmasq is already installed and running on the server but rdns record is not available in /etc/hosts when I create new OpenStack VM.

After I create VMs in openstack, it should configure automatically in /etc/hosts.

Is there any way to enable reverse DNS with neutron network?

2016-02-10 07:29:29 -0500 回答问题 unable to add rules in security group

leave it..

This is because of port is already exits but openstack horizon UI does not show like already exits. It shows only "Error: Unable to add rule to security group."

2016-02-10 07:19:20 -0500 问了问题 unable to add rules in security group

I have installed packstack for our openstack installation. It seems to be working fine but some times unable to add rules in security group.

This happens randomly in our openstack environment. Sometimes added successfully and sometimes added failed.

Anyone having like this issue?
