could you able to ping both the controller and external network. we should add the two rules from dashboard to access the VM's.

2015-02-23 22:04:07 -0500 answered a question cannot see cinder-volume in cinder service-list

Hi Rohit,

I think in your environment cinder tables are not created, once check the cinder tables in database like the below command :

# mysql -u root -p

MariaDB [(none)]>  use  cinder;

MariaDB [cinder]> show tables;

it will show tables in cinder database. if the database tables are not created then create the database tables again like the below command :

  su -s /bin/sh -c "cinder-manage db sync" cinder

Hi Sumesh,

By seeing your logs sheepdog file is not found once install sheepdog with python cinderclient as given below

# apt-get install sheepdog python-cinderclient

After installing sheepdog restart the glance api and registry services

# service glance-api restart

# service glance-registry restart

then create the glance image and let me know if there is any another issue.

2015-02-20 03:38:29 -0500 commented answer im able to ping between instance to external gateway of my router but im not able to ping google from my instance

did you add the two rules (All ICMP and SSH) through the horizon to that VM?

For connecting and accessing the VM we have to add those two rules.

Hi vignesh, may be this is due to VM is blocking the data, Once run this command

#   iptables -F

in the VM and check it once by using

  ping VM_ip-address
2015-02-19 06:43:11 -0500 answered a question Can ping vm instance but can't ssh (ssh command halts, with no output)

I think we should add two rules to ping and ssh an VM .

why should we add these rules because we can access the data in a secure way so that's why we have to add All ICMP and SSH rules through the horizon. so check the horizon did you add those rules or not.

2015-02-19 05:21:14 -0500 commented answer Nova-compute not showing on nova service-list(controller)

the mapping between hosts name and ip addresses may be went wrong in the etc/hosts. once again check the rabbitmq-server credentials in nova.conf like

  vi  /etc/nova/nova.conf

could you please display the compute log files once again?

2015-02-18 12:02:06 -0500 answered a question Nova-compute not showing on nova service-list(controller)

Hi Oscar,

By seeing the log you pasted here, it seems like nova conductor is not running.

once check the status of nova-conductor like

 service nova-conductor  status

if the status of nova-conductor is down, restart the nova-conductor service like

 service nova-conductor restart

so once again restart the services like mysql,rabbitmq-server and all nova services. if there is any another issue let me know.

2015-02-18 03:50:56 -0500 commented question nova network create fails with The server has either erred or is incapable of performing the requested operation. (HTTP 500)

Your issue likely to be with firewall, Check if you can telnet from compute node to your controller node using port 5672 Ex: telnet controller 5672 If its refuses the connection then you need to disbale the firewall. But before doing check if rabbit server is up and running

Hi jide, Here we have to see two points :

1) Check whether rabbitmq-server is in active state or not.

2) If Rabbitmq-server is in down once again check the rabbit-mq credentials in /etc/nova/nova.conf and

  restart all the nova services and rabbitmq-server.

2015-02-17 12:15:14 -0500 answered a question Problem when suspend instances

Hi XicoLoco, I think you are trying to host a KVM box instead of qemu. once go through this http://docs.openstack.org/juno/install-guide/install/apt/content/ch_nova.html (link text) From the guide: If you install Compute on a virtual machine for testing purposes, you must determine whether your hypervisor and/or CPU support nested hardware acceleration using the following command:

egrep  -c '(vmx|svm)' /proc/cpuinfo

If this command returns a value of one or greater, your hypervisor and/or CPU support nested hardware acceleration which requires no additional configuration.

If this command returns a value of zero, your hypervisor and/or CPU do not support nested hardware acceleration and libvirt must use QEMU instead of KVM. Edit the [libvirt] section in the /etc/nova/nova-compute.conf file to modify this key:

[libvirt]
... 
virt_type = qemu

Hi michael-chin1979 , like Soren told we can install each component in each server or all nova components in one server. but we have to specify where we are installing nova-api while creating an end-point to the nova-api and we have to specify the location of the components where ever required.

2015-02-16 15:23:47 -0500 answered a question Unable to reach the virtual machine instances in the openstack cloud from the host machine

Hi , we have to add two rules (SSH and All ICMP) after creating VM's mostly through web interface dashboard. first of all check whether you can ping to physical machine (172.X.X.X ) from 10.0.3.X or not if the controller is not pinging, run iptable -F command in controller and again try to ping.

2015-02-16 15:23:39 -0500 answered a question Dashboard error with Juno and neutron

Hi Joloughlin , Could you please check nova-configurations. May be some configurations are pointing to neutron.once go to the file (vi /etc/openstack-dashboard/local_settings.py), check the argument

OPENSTACK_NEUTRON_NETWORK = { 'enable_lb': False }

if it is set to true then change like 'enable_lb':False then, restart apache2, memcached services and it's better to restart all the services.
