ConVirt provides enterprise-class management of open source virtualization platforms, making open source virtualization an extremely viable and cost-effective choice for enterprises. ConVirt lets you manage the complete lifecycle of Xen and KVM virtualization platforms from a central, GUI dashboard. With sophisticated template-based provisioning, centralized monitoring, configuration management and administration, IT administrators can now automate the entire virtual machine lifecycle on open source platforms. ConVirt is an open source product backed by commercial, enterprise-class support, so you get the best of both worlds: a sophisticated, commercially-backed solution that is also highly cost effective.

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
rsync hfsmode is a patch for rsync to enable recognition of Mac OS X HFS resource forks and Finder metadata, and to copy them to a remote filesystem. The destination system can be any OS and filesystem that supports rsync, so you can use rsync to archive Mac OS X files to servers running Linux, Solaris, et cetera.
mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 8.10 server.
Tired of the same old punditry and OS wars? Want to read something practical you can actually use and apply to your real job? Or perhaps you need some light reading material to help you get some sleep on the plane between consulting engagements – either
Slony-I is a "master to multiple slaves" replication system supporting cascading (e.g. - a node can feed another node which feeds another node...) and failover.
