Re: [one-users] 802.1q tagging
I was referring to creating vlan devices with vconfig. So you create multiple vlan devices on the host and associate each with separate bridge. However the switch that is used to connect multiple hosts should not add its own VLAN tag. It must be capable of forwarding VLAN tagged traffic. This is only addressing separation of networks and intra-VM communication within the Cloud. I think openvswitch does the same thing and more. Atleast what I gather from here. http://openvswitch.org/?page_id=146 In case when you want a VM in the private cloud to be part of your organization VLAN then the packet leaving your VM should carry the VLAN tag configured in the switch. Obviously all the VM's using that bridge are part of one network. On Sun, Dec 19, 2010 at 11:05 AM, Shi Jin jinzish...@gmail.com wrote: I am curious about the same thing.

Re: [one-users] Difficulty in accessing the virtual instance
Hi, I tried to use the contextualization in the template file. But everytime I create the instance, it fails at boot time saying tap device could not be connected. I belive this is the problem with xen. Is there any way I can change the driver of the iso file created by the opennebula when the instance is created.

Re: [one-users] 802.1q tagging
Thank you all for the information. I was having difficulties figuring out how to handle vlan tagging. I realized the dom0 must have a tagged interface connected to a seperate bridge (as Rangababu described). Since OpenNebula allows you to specify the bridge in the vnet definition it all just works properly (given the bridge is setup on all of the onehosts). Our guest OSes have a pool of addresses from many disperse /24s. Using vlan tagging, allows us to use the same IP address anywhere in the datacenter (no need to map which /24 must come up on a specific dom0). Also, useful when migrating VMs as well.

[one-users] multipart post
I have been working on a portal (which I will submit back to the eco-system) at some point. The portal interacts with OpenNebula via OCCI. Since the portal runs on a different system than the controller, I have written a very basic OCCI client. I was looking at the following documentation, and a bit confused by it. Has anyone had any luck doing what is described below in curl? Looking at the OCCI server, it looks as though it expects a multipart-post with the image file? http://www.opennebula.org/documentation:rel2.2:occiug -- Storage Assuming we have a working Gentoo installation residing in an .img file, we can upload it into the OpenNebula OCCIcloud using the following OCCI representation of the image: STORAGE NAMEUbuntu Desktop/NAME DESCRIPTIONUbuntu 10.04 desktop for students./DESCRIPTION TYPEOS/TYPE URLfile:///images/ubuntu/jaunty.img/URL /STORAGE -- ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
