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
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.
P2V stands for Physical to Virtual. In other words, it is the process or procedure of moving a running system (operating system and everything installed) from a physical machine to a virtual machine.
