Hi All. I plan to use virtualization in my production environment. I plan to use one of the following options: - KVM; - VMWare Esxi; - VMWare Workstation. I plan to install Windows 2008 as a guest. I want to use something like LVM snapshots for backups. Stability is also very important, the guest will be used as a production server. Which option could You recommend and why? Thank You very much in advance :) With regards, R. -------------- next part -------------- An HTML attachment was scrubbed...

The main "missing" feature is software raid, which isn't recommended nor supported for production, but can be achieved on test machines. But beware that with KVM you will almost certainly need a good HW raid with bbu cache. Also the development is very active and more functionalities are coming on each version (shared storage via drbd, and many other, I think that the wiki can cover this better) HTH Regards, Lorenzo

VMware Esxi is probably the best if the windows guest(s) are the main priority. I think you need a windows box to run the vSphere client to manage it, though (but it is very nice, letting you do things like connect your client cd/dvd to the guest for installs, etc.) VMware server would be OK if the guest(s) are somewhat secondary and you also run some services directly on the host. It has the down side that whenever you update the host kernel you need to reboot the guests and run through the configuration step before they'll restart. -- Les Mikesell lesmikesell at gmail.com

Always been good for me, however lately I have been trying out Virtualbox (PUEL) :-). They have an Open Source Edition also (Virtualbox), only it lacks USB Support. If you go on there website, you can see the 3 missing features. Tried KVM, but it didn't like my box not having AMD-V. I think the best way to determine what's best for you, would be to try them all, and see which you prefer :-) -- Jake

I wouldn't use Vmware Server/Workstation for a production server, either. I found VMWare server 2.x quite unstable on a number of different configurations, and the performance is considerably lower than the native hypervisor style virtualization like ESX(i) VMWare ESX(i), assuming your hardware is supported, works great. Rock solid, very good performance, excellent support for windows, linux, solaris, etc guests. VMware supports copy-on-write snapshots, too. re backups, you do know Windows Server has its own snapshot feature for taking backups, known as VSS (Volume Snapshot Services) ? do note, snapshots are an AID to backups, they aren't a substitute for proper offsite archived backups for emergency recovery. For instance, they won't protect against system hardware failure. Any, a volume with too many snapshots pending tends to bog down considerably in disk IO performance.

Some experiences I've had: VMWare Server Runs well on CentOS, though there are some workarounds to keep in mind. As of today, you'll need to do some library tweaking to get it to run with the latest glibc. Also, the latest Firefox 3.6 has issues running the administration console. No support for LVM volumes (which can be problematic when doing LVM snapshots on the host side). Networking is easy to configure. Very polished front-end. Guest images can be converted to work with ESXi and vice versa. File based backup so you *can* do snapshots. I haven't figured out how to script it yet, however. VMWare ESXi Works well (though is not CentOS). Much more enterprise support options. Has a scripting back-end which is quite useful. Commercial support options available. Management of the host itself is different from CentOS. KVM Runs Linux guests quite well, especially RedHat/CentOS/Fedora installations. Windows installations didn't go as smoothly. Can be scripted very easily so multiple deployments are trivial. Glitches in the GUI management tool (mouse tracking is horrible). Not so easy to configure networking. Performance seems pretty good, though I don't have identical hardware to test versus VMWare. Supports LVM volumes as back-end storage for the VMs so you can do snapshot backups. I'm awaiting support for memory de-duplication on the host side as this can really help cram more VMs into a box (my workloads are very light on memory/cpu but libraries/packages change daily). Xen>From the CentOS side it's very similar to KVM if you use the virttools. Performance is extremely good with paravirtualized machines. It's a workhorse and quite stable, but the GUI is not so great. Networking is a bear to configure. Requires a separate kernel. I've never quite gotten the Xen migration to work. VirtualBox GUI is not bad. Networking was a bear to configure. Major issue with performance that still is not fully fixed (host CPUs pegged even when guests are idle).
