jaymc Posted April 19, 2008 Share Posted April 19, 2008 I'm going to be buying some monster servers soon with intension of partitioning the hardware to run multiple instances of centos, hence virtual I've used vmware but its rather pricey. I've heard of xen which is free. Has anyone successfully used this? If I'm looking to save on the dollar but still have a good setup what should I be looking into.

neylitalo Posted April 19, 2008 Share Posted April 19, 2008 I have not configured a xen system, but I've used one, and I love it. I don't have a need for that level of virtualization in my systems, so I just use qemu and the Linux Kernel-based Virtual Machine. Quote Link to comment Share on other sites More sharing options...

trq Posted April 20, 2008 Share Posted April 20, 2008 I've been using openVZ at home for quite some time. My hired VPS's also are built using openVZ. I had allot of trouble getting a working kernel going with the xen patches, openVZ was a breeze. I was even able to set it up on my desktop machine here at home. Its easy to configure, and has all the features you would need including a nice setup script vzsplit where you tell it how many vps's your planning on building and it will query your memory and create a nice default configuration. I was able to get about 6 machines running on my old 2.4Ghz with 512Mg memory. Recently I bought a dual core 3Ghz machine with 8G of memory, I'm still in the process of setting it all up but expect to be able to run upwards of 40 vps's.

jaymc Posted April 20, 2008 Author Share Posted April 20, 2008 Do you install openVZ as the base operating system? Or is it an application that runs over the top of existing OS like centos etc Quote Link to comment Share on other sites More sharing options...
trq Posted April 21, 2008 Share Posted April 21, 2008 openVZ is a set of kernel patches as well as userspace tools built to run within a linux OS. Quote Link to comment Share on other sites More sharing options...
steviewdr Posted April 22, 2008 Share Posted April 22, 2008 Im a big Xen fan. If you use Debian/Ubuntu, its a walk in the park to setup Xen. If your buying hardware/cpu's, make sure they have virtualisation support built in. Why do I like Xen....well 100's of reasons: Using munin, I can monitor each part of a virtual instance (memory,cpu,traffic etc.). See: http://muninexchange.projects.linpro.no/?search=&cid=0&os%5B4%5D=on&os%5B7%5D=on&os%5B3%5D=on&os%5B2%5D=on&os%5B5%5D=on&os%5B8%5D=on&os%5B1%5D=on&os%5B6%5D=on&pid=39 There is something called xen-shell which will give a user console access to their virtual machine. http://www.xen-tools.org/software/xen-shell/ It comes with a number of networking options built in. Either create a private army of xen vm's or use bridged networking to give each one a public ip etc. Of course there are loads of other options and there are the downsides. Here is my how-to on installing xen: http://wiki.kartbuilding.net/index.php/Debian_Etch_Xen_Install -steve Quote Link to comment Share on other sites More sharing options...
