Hi, On my CentOs6.2 system, I have installed the openstack as specified in the openstack installation guide. In my openstack system, i have one controller node and 2 compute nodes. One compute node is on controller node and other is on different node. I used nova networking for IP allocation. I have following configuration of openstack on my systems.

On my controller and 1st compute node following services run :

  • openstack-nova-api
  • openstack-nova-cert
  • openstack-nova-compute
  • openstack-nova-network
  • openstack-nova-scheduler
  • openstack-nova-conductor
  • openstack-glance-api
  • openstack-glance-registry
  • openstack-keystone
  • openstack-dashboard
  • mysqld
  • libvirtd
  • messagebus
  • qpidd
  • memcached

And on 2nd compute node following services run :

  • openstack-nova-compute
  • openstack-nova-metadata-api
  • openstack-nova-network
  • libvirtd
  • messagebus
  • qpidd
  • memcached

Using the above configuration, when i launch the instance for "cirros" image then the instance run successfully and login to instances also works fine. And when i launch instances for the other images(some downloaded from the openstack site and some created via the virtual box VMDK, VDI and VHD files), then it shows the instance in running state but login to instance fails. For "CentOS" images, some times the console hangs on the green loading screen and does not ask for login credentials and some time it shows the following error messages.

udevd[490]: worker [514] unexpectedly returned with status 0x0100
udevd[490]: worker [514] failed while handling '/devices/LNXSYSTM:00/LNXPWRBN:00/input/input0'
udevd[490]: worker [516] unexpectedly returned with status 0x0100
udevd[490]: worker [516] failed while handling '/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:00'
udevd[490]: worker [524] unexpectedly returned with status 0x0100
udevd[490]: worker [524] failed while handling '/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A03:00/device:01'

And for "Ubuntu" images, console show the logs for more than 40 minutes and after that it shows the login screen.

I am unable to launch instances for CentOS and Ubuntu images using the above configuration. If anybody faced such issue then please assist me to fix it.

Hi Prathamesh, thanks for the response. My problem is later one. The instance launch works fine and it also goes to running state, but it takes lot of time to go in running state and second, the login to machine does not work. When i log-in to machine, it shows Read from socket failed: Connection reset by peer. Some time it also shows ssh: connect to host port 22: No route to host.

Hi Hokam, Are you not able to launch instances other than CirrOS or are you not able to login to the instances ? If you are facing first issue, then can you please paste nova-scheduler/nova-compute logs. For the latter part, try connecting to the instances using the nova keypair: `ssh -i key.pem root@` this is for the Ubuntu image, key.pem is the keypair and ip of the ubuntu instance is hope this helps
