This guide explans how you can install and use KVM for creating and running virtual machines on an Ubuntu 9.10 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V. I do not issue any guarantee that this will work for you!
We were unable to find any info googling. It appears you cannot boot a Paravirtualized DomU directly to CD-ROM? So we temporarily changed our Paravirtual Xen DomU to boot from HVM or Full Virtual Machine. Our environment has Xen running on HVM capable hardware (we can run Full Virtualization) with LVM Block devices for disks. Our Paravirtual DomU is called guest-1 First backup your Running Xen config. Save it to /etc/xen/vm/guest-1.run xm list -l guest-1 >/etc/xen/vm/guest-1.run You will use this file later on. Novell’s documentation on how to save Running Xen DomU config. http://www.novell.com/documentation/vmserver/pdfdoc/config_options/config_options.pdf Look for “Virtual Machine Settings”. I found it easier to modify the startup config in /etc/xen/vm/guest-1 than modify the file that is outputted from the Novell Running config backup. Backup the original Startup config (I believe this file gets created when you first build a new VM in virt-manager.)
Does anyone know of Best Practices for virtual machine backups? Is there anything published? Is there a need to define best practices for XenServer backups? !!!See script details in thread!!!!
The xen-vm-autosnapshot.py script has been updated with an important new option: –snapshot-tag. I still can’t believe I made such a silly oversight, but previous versions of this script had no way of differentiating between snapshots created automatically and those that were created manually. So if you happened to have some old manual snapshots lying around, the snapshot-rotate routine would have rotated them along with all the rest.
backing up your xen domains posted february 10th, 2008 by john in debian etch tech xen backups are boring, but we all know how important they are. backups can also be quite powerful when working with xen virtualization, since xen allows for convenient back-up and restore of entire systems. i've recently been working on a flexible, general-purpose script enabling incremental backups of complete xen guests, optimized for secure, distributed environments
As many of you already know, virtualization is big, and it continues to grow in popularity. Users are now actively seeking complementary solutions to extend the virtual infrastructure across the entire enterprise, from storage to server to desktop. The move to "Total Enterprise Virtualization" is real and might be taking place in your organization right now. Today, virtualization is understood as a comprehensive infrastructure solution that is absolutely strategic to a competitive business.
VRDP is a compatible implementation of Microsoft’s Remote Desktop Protocol (RDP) that is configured for easy console access to the guest platform from remote systems. This is different from a web-based interface that the competition has in that it is configurable per virtual machine. Let’s take a look at how to configure VRDP for a virtual machine in these steps below.
There are several ways to install Open Virtual Desktop, depending on the target host flavour. First of all, you need to read the documentation to learn how to install it. Please select your downloads below. New: we now provide an DVD ISO to install all the system. See below "Installation from a DVD ISO". Please read the documentation anyway!
I started in August 2005 a project to emulate a Cisco 7200 on a traditionnal PC. Now, it also supports Cisco 3600 series (3620, 3640 and 3660), 3700 series (3725, 3745) and 2600 series (2610 to 2650XM, 2691). The goals of this emulator are mainly: * To be used as a training platform, with software used in real world. It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies
If you're reading this, you already know the news: XenServer, our enterprise virtual infrastructure platform is now free (including resource pooling and live relo), and we have announced Citrix Essentials for XenServer, and Citrix Essentials for Hyper-V as our virtualization management portfolio that offers a rich set of automated functions that drive the compatible virtualization layers beneath - the free Hyper-V hypervisor from Microsoft, and the free XenServer Enterprise virtual infrastructure platform from Citrix. Finally, and most importanly, we announced a powerful go-to-market roadmap with Microsoft.
n the event that something happens to a Xen virtual machine (VM) that prevents you from starting it, it's a good practice to have the virtual machine storage back end mounted in the Linux file system of the Xen-based server. By doing so, you'll be able to repair the VM quickly and painlessly. In this tip, I'll cover how to do this for physical devices that are used as storage back ends.
The newest version of the open source Xen hypervisor has been released, and it features input from some of the industry's largest hardware and software players. The new release boasts better performance and scalability and is designed to work on supercomputers, smartphones and everything in between.
