ConVirt: the New Tool in Your Virtual Toolbox

The navigation pane is logically divided into a tree with your Data Center at the top with Server Pools and Templates listed underneath it. This outline reflects how resources are organized in ConVirt: Data Center→Server Pool→Managed Server (host)→Guest. Your Data Center is the top-most delineation of your virtual environment. It could be a site or an organizational unit. Under the Data Center are Server Pools that group together like managed servers that share common items like storage and virtual network configurations. Managed servers are placed in the server pools along with any guests/VMs that reside on them. Templates fall into their own category, but also are available from the navigation pane. Templates are pre-configured groups of settings used at provisioning time to carve up/define the virtual resources available to new guests (processors, memory, storage and NICS).

The next step in your deployment is to prepare your hosts to become managed servers. Specific hypervisors have individual requirements before being added to the CMS, but the process for preparing each host is roughly the same for each. Create a network bridge on each host, download the ConVirt tool from the site and install any dependencies. Then configure SSH on each managed/server host for root access, and finally, run the convirt-tool setup command. Debian/Ubuntu users should note that you will need to set a password on the root account manually in order to manage any hypervisor from the CMS. I also suggest that you name any bridges you create with identical names (for example, KVM=br0, Xen=Xenbr0), as this helps standardize your guests' networking options. For this article, I created two KVM servers and one Xen server to manage with ConVirt.

With the hosts prepared, you now can add them to the CMS. This starts by adding hosts to a server pool. You can use the pre-configured Server Pools (Desktop, Server, QA Lab) or create your own. I created an additional pool to play with that I named "Production", and in case I messed anything up, it wouldn't affect the default pools. When you have your pool selected, right-click on it and select Add Server. On the resulting screen, select your platform, either Xen or KVM, and fill in the hostname or IP address.

If you have not configured SSH for root access on the host, the server will fail. If the server is added successfully, it now should display under the server pool you chose with a little K (K) or X (Xen) icon (Figure 3). Click on the newly added server to see performance information about your host displayed in the center pane (Figure 4). From this display, you also can view the number, type and status of the guest running on the host.

So they even want money for this web page.....
Maybe someone should finally tell linux developers that there is something that is called an application. You know it has a gui, it actually is doing something and so on. You know the software - not the webpages or yet another simple whatever crap all fanboys are excited about even they can't use it as it have no functionality.
Anyone?

Why the hell are you using

Why the hell are you using windows on a linux journal?

Hey God - You may not be verified, but you sure are a fundamentalist..!

Nice to see some

Nice to see some centralization for kvm and virt-manager, but a CMS with root access to my hosts and by extension guests.. pass.

However, big +1 for being open source. Won't be long before we see the host scripts adding specific user for the CMS and adding ACLs, or at the very least using keypairs.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
