Re: [Openstack] Namespaces and network

Hi Janki, I am totally agree with Chen. It seems you are new to Openstack, and therefore I would like to suggest you that it would be better if you follow three node installation. For that here is a reference link : https://github.com/ChaimaGhribi/OpenStack-Icehouse-Installation/blob/master/OpenSt

Re: [Openstack] Namespaces and network

Hi, From my understanding: 1. Namespace is created by neutron-dhcp-agent. You can run neutron-dhcp-agent anywhere you want. It is common to run neutron-dhcp-agent on control node, but it is not a “MUST” demand. I won’t say the network “is created in Compute node ”, a network is

Thanks Julie, From the bug report,it looks like changes are for nova.py and cinder.py.Will changing these two files fixes this issue or do i need to make changes in more files.Thanks for your help Julie Pichon. On Thu, Jan 15, 2015 at 9:59 PM, Julie Pichon wrote: > On 15/01/

[Openstack] Namespaces and network

Hi ALL I have doubts. I am having a 3 node architecture with Neutron. 1. Whenever we create a network, it is created in Compute node and its namespace is stored in Control node. Instances will be created in compute node. Is my understanding correct? 2. Why do we need 2 ovs bridges br-int, br-ex

Re: [Openstack] How to set up the external connection with Linux bridge using DevStack?

Hi, The OVS does not have so many different with linux bridge, the concepts are the same, but differ is commands and the way to handle them. You can NAT one of the linux bridge or MASQUERADE it in order to interact with external network. :) I think DNSMasq will be helpful. Sincerely, Salehi On

[Openstack] How to set up the external connection with Linux bridge using DevStack?

Hi, In the OVS world, at the Network node, we create a external bridge, e.g. br-ex, to connect the os-router to the outside world so that we can assign floating IP to the VM and access the VM externally. How to do that with Linux bridge? What do I need to set in local.conf? Thanks, Danny _

Re: [Openstack] [SWIFT] Bad replication performance after adding new drives

My xfs inode size is 265 Bytes. When I increase the memory and change vm.vfs_cache_pressure to 1, is it possible to store the inode tree in the memory? Maybe the random disk seeks are the problem. My disks are all Hitachi SATA 3 or 4 TB with 7.200 rpm. The movement of 1250 partitions should go

Hi Khayam, the Fn::FindInMap is not supported in HOT as far as I can see in the code. The list of functions supported in the HOT version you are using is defined in this part of the code: https://github.com/openstack/heat/blob/master/heat/engine/hot/template.py#L274 The list for version 2013-05-
