Also you can find install guide here http://docs.openstack.org/diablo/openstack-compute/install/content/index.html (http://docs.openstack.org/diablo/open...) starter guide at http://docs.openstack.org/diablo/openstack-compute/starter/content/ (http://docs.openstack.org/diablo/open...)

2012-02-07 11:14:49 -0500 answered a question Installing Nova on Ubuntu 10.04

Yes, you can install Nova on physical machine running Ubuntu 10.04. Make sure a hypervisor is running in your machine. Ex: KVM. A supported hypervisor is required by nova-compute. You might want to refer to hypervisor support matrix here http://wiki.openstack.org/HypervisorSupportMatrix (http://wiki.openstack.org/HypervisorS...)

Hope that helps!

2012-02-01 15:45:25 -0500 answered a question ESXi and nova-compute

Deployment of OpenStack on ESX/ESXi slightly differs from that on KVM. The nova modules won't be installed on ESX/ESXi host directly, but on a VM over the same host (recommended) or external server.

For flags, you can refer to readme at http://nova.openstack.org/vmwareapi_readme.html (http://nova.openstack.org/vmwareapi_r...)

For example, I install nova inside my ubuntu VM that runs on the same ESX host. Here is a snippet from nova.conf from the ubuntu VM, where 10.0.120.11 is IP of my ESX host.

---snip---nova.conf file:

--connection_type=vmwareapi --vmwareapi_host_ip=10.0.120.11 --vmwareapi_host_username=root --vmwareapi_host_password=password --vmwareapi_wsdl_loc=http://10.0.120.9:8080/vimService.wsdl

---snip---nova.conf file

Hope that helps

2011-12-29 10:02:55 -0500 answered a question configuring FlatManager & injecting IP address

By default, the flag flat_injected is False. Hence injection doesn't happen.

Can you add the flag --flat_injected=True to configuration file and try?

Hi Asok,

The following command would give you nova.zip file. nova-manage project zipfile $NOVA_PROJECT $NOVA_PROJECT_USER unzip nova.zip After unzipping nova.zip, you can see "novarc" file that consists of the required environment variables/settings like access key of $NOVA_PROJECT_USER. Just source the file "novarc" and you will be ready to run euca2ools commands :-)

Hope that helps!

2011-11-16 09:09:55 -0500 answered a question how to add ovf genenrated by vmware

Current vmwareapi driver of nova supports only thick flat vmdk disk. So you can try upload flat vmdk disk with container format as 'bare'

2011-11-10 06:48:05 -0500 answered a question Openstack nova.conf setting

No we are not restricted to MySQL, PostgreSQL or sqlite. OpenStack uses sqlachemy as db layer to allow flexibility to choose between the pluggable DB backends. Hence you can use any database (oracle, MSSQL Server, Informix, Sybase etc.) what ever sqlalchemy supports. You can refer to SqlAlchemy's documentation to know more.

2011-11-09 09:38:19 -0500 answered a question Openstack nova.conf setting

Which database are you looking to connect to?

For mysql, --sql_connection=mysql://USER:PASSWORD@HOST/nova

for your environment, you can use, --sql_connection=mysql://novadbadmin:novasecret@10.10.10.2/nova

Hope that helps!

Can you check mysql/db connectivity from server 2 which is running nova-compute service?

Also can you verify nova.conf if it's having correct flags for sql_connection flag?

2011-10-26 07:27:02 -0500 answered a question How to use multipart VMDKs

Hi Jason,

Nova vmwareapi driver supports only the vmdk image format of "Monolithic File Flat" which is thick (pre-allocate). I suggest to convert the split images to a single monolithic flat file before trying to use with openstack.

Few useful links for disk conversion, http://www.vmware.com/pdf/VirtualDiskManager.pdf (http://www.vmware.com/pdf/VirtualDisk...)

Hope that helps!

2011-10-09 05:00:33 -0500 answered a question Adding a new hypervisor to openstack

Need to add virt driver for the new hypervisor. You can look at the current virt drivers (like xenapi, vmwareapi) in the directory nova/virt/.

2011-09-30 07:06:56 -0500 answered a question Nova Class not found error

Are you getting the same error still? Can you paste the error, otherwise?

--glance_api_servers=10.37.39.57:9774 Also I think you need to provide port 9292 for glance api servers. Like, --glance_api_servers=10.37.39.57:9292

2011-09-29 09:53:31 -0500 answered a question OpenStack Installation on VMware with one interface card Possible ???

OpenStack installation works good on VMware ESX/ESXi 4.1 or later. One physical NIC server would be enough.

For flags, you can refer to readme at http://nova.openstack.org/vmwareapi_readme.html (http://nova.openstack.org/vmwareapi_r...) on ESX/ESXi server, you do not need to edit any file like /etc/network/interfaces.

Here is nova.conf from a working setup,

nova.conf file: --daemonize=1 --dhcpbridge_flagfile=/etc/nova/nova.conf --dhcpbridge=/opt/openStack/bin/nova-dhcpbridge --lock_path=/tmp --logdir=/var/log/nova --state_path=/var/lib/nova --verbose --network_manager=nova.network.manager.FlatManager --sql_connection=mysql://root:password@127.0.0.1/nova --rabbit_host=127.0.0.1 --ec2_host=127.0.0.1 --image_service=nova.image.glance.GlanceImageService --glance_api_servers=127.0.0.1:9292 --use_s3=false --connection_type=vmwareapi --vmwareapi_host_ip=10.0.120.11 --vmwareapi_host_username=root --vmwareapi_host_password=password --vmwareapi_wsdl_loc=http://10.0.120.9:8080/vimService.wsdl --console_manager=nova.console.vmrc_manager.ConsoleVMRCManager

2011-09-27 03:59:00 -0500 answered a question Compute VMWare ESXi 4.1 connection refused

While creating instance, the instance will be connected to the specified bridge (as you are using FlatManager for networking) using the flag "--flat_network_bridge". If no bridge specified then br100 will be used. Here the error says br100 network (port group name) doesn't exist in ESX host. You can either try to create a port group with name 'br100' or specify the name of existing port group against this flag.

Option description:- --flat_network_bridge=<esx virtual="" machine="" port="" group=""> [Optional, only for Flat Networking]

Hope that helps!

Hi Joe,

Did you try to enable “vSphere Web Access” in “vSphere client” UI at Configuration->Security Profile->Firewall

Also make sure vim.wsdl is also hosted at the location as that of vimService.wsdl.

Which version/revision of nova are you using?

2011-09-23 10:21:54 -0500 answered a question Single Node: EC2_ACCESS_KEY environment variable must be set?

Cool :-)

2011-09-23 08:17:32 -0500 answered a question Single Node: EC2_ACCESS_KEY environment variable must be set?

Hi Ahok,

You need to generate the credentials and source the file novarc to environment variable EC2_ACCESS_KEY and EC2_SECRET_KEY, whether it's single node or multi node installation.

You can find the instructions here, http://docs.openstack.org/openstack-compute/admin/content/ch03s03.html#d5e314 (http://docs.openstack.org/openstack-c...)

2011-09-22 04:13:08 -0500 answered a question Error when starting nova-network

Is the flag --sql-connection specified such that nova service does know which sql server it should connect to?

2011-09-21 12:29:58 -0500 answered a question ClientConnectionError: Unable to connect to server.

I see that your glance services are running on -glance_api_servers=10.207.230.122:9292 as per the flags specified in the above description, but you are trying telnet to 10.207.230.126:9292. If 10.207.230.126 is the server with glance running, please upate the flags accordingly.

Hope that helps.

2011-09-21 12:21:08 -0500 answered a question xenapi-vlan-network-manager and xenapi_net.py

For vlan environment, we don't need to mention the flag --network_driver for nova-compute service. Instead we have new flag 'xenapi_vif_driver' which defaults to nova.virt.xenapi.vif.XenAPIBridgeDriver if not specified in configuration file. For default vlan environment in on xen flavors, we don't need to specify this either.

In nova revision 1321 (merged into nova on 26th July 2011) xenapi_net.py is removed. In that revision the VIF network connectivity logic is moved from the network managers to the virt layer. In addition, VIF driver class is added to allow customized VIF configurations for various types of VIFs and underlying network technologies.

2011-09-21 10:42:41 -0500 answered a question nova.conf - controller vs compute node

Compute node knows that controller node through the flags specified in nova.conf

The details of flags to be modified is in openstack documentaion (link below) http://docs.openstack.org/cactus/openstack-compute/admin/content/configuring-multiple-compute-nodes.html (http://docs.openstack.org/cactus/open...)

Essentially the flags specify where the services the cloud wide-services like api, rabbitmq, mysql, glance etc. are running.

2011-09-21 10:33:57 -0500 answered a question ClientConnectionError: Unable to connect to server.

It looks like your glance server is accessible from compute node. Can you try telnet to glance ports (9292,9191)?

Hope your glance server is bound to address 0.0.0.0, this can be verified in glance configuration files Also, in case if you modify the configuration file nova.conf, make sure nova-compute service is restarted.

2011-05-25 11:47:26 -0500 answered a question Can someone provide me with the proper syntax for vmwareapi_host_ip nova.conf flag?

Notation is, IP address of ESX/ESXi Server has to be provided after '='

Format: --vmwareapi_host_ip=<ip of="" the="" esx="" host="">

Example: Assume the IP of ESX/ESXi server is 10.102.123.220 then the flag looks like, --vmwareapi_host_ip=10.102.123.220
