I'm building a new server at home to handle most of my internal requirements (mail, news, dns, dhcp, backups being the biggies). I also want it to host a couple of virtual servers which are allowed incoming connections from the internet (mail gateway, web server, ssh server); these are virtual so if a hacker _can_ break in then they're limited as to what they can see. At present the virtual machines are vserver instances on an old FC2 box. I'm wondering what people recommend for virtual servers these days? CentOS 4 with a vserver kernel? Wait for CentOS 5 and use Xen? VMware? (Vmware is the heavy solution, but it does mean I could host a windows session if I wanted to). Or Solaris 10 and zones? Any thoughts? -- rgds Stephen

U should give a try to FC6 with Xen for virtualization , its really cool?

It is worth looking at. IYup, I mentioned that as an option on my initial list. I've got a test box running CentOS 4.4 and VMware. It's a heavy weight solution, but has advantages (I could potentially run Solaris 86 in a session, Windows in a session etc).> used to run a bunch of vserver instances, and while those did have some > interesting advantages, I ended up rebuilding everything using VMware Server as > I retired hardware.

Thanks for your input! -- rgds Stephen

Or Solaris 10 and zones?Personally I'm using VMWare-workstation, but it isn't an ideal solution: - it costs - it is hard to make VMs start at system boot - it is a heavyweight solution The reason I am using -Workstatin as opposed to the free -Server offering is because -Server does not provide some virtual hardware that is useful in a workstation environment. I find it odd what drives your requirements in the end. In my particular case, I am connecting to a Windows VM through a Sun Ray session, and found my Windows VMs were less usefull without the sound devices because Windows Movie Maker would not start on a system which lacked a sound card. (And I wanted Windows Movie Maker to convert video streams from the high-bitrate that comes from the camera down to something a little more portable, not to actually view anything.) I am probably going to split things up, though -- I have an older system which I will move the Windows VMs to, and then run -Server on my main system so I can do the other virtualization things I want to (mostly experimenting with other OSs and sandboxing software packages I am playing with) much easier. I have a 900-series Intel Core Duo processor, purchased expressly so that I could do Xen and the like but have found that they are not quite ready for the kind of use I want to put them to. -- /\oo/\ / /()\ \ David Mackintosh | dave at xdroop.com | http://www.xdroop.com -------------- next part -------------- A non-text attachment was scrubbed...

The Centos box does a swag of tasks, including, openvz kernel (complete with virtual DMZ) Vmware server NFS server SMB Server courier imap (with mysql auth) oracle postfix (with virtual domains and mysql lookups) bacula squid cache Fedora Directory Server and it never misses a beat.

centos 4.x using vmware server will fill th needs nicely. You have the long term lifespan of the RHEL branch and your virtualization taken care of in one fell swoop and you can't beat the price..<G> Stephen Harris wrote:> I'm building a new server at home to handle most of my internal > requirements (mail, news, dns, dhcp, backups being the biggies).

How memory-intensive is VMWare workstation? I have a P4 3.0GHz with 1/2Gb of memory at home - is VMWare going to be a total drag on the system or is it lightweight enough that I can still run (as opposed to walk or crawl)? I run VMWW at work, but that's a Pentium-D with 2Gb of RAM, and top shows vmware using 199m virt, 1.1g res and 1.1g shr - not sure what that means (but it looks like bad news for the home situation...). Thanks.
