RE: [Xen-users] Xen Setup

["Alan" <alan@xxxxxxxxxxxxx>]

We don’t do anything fancy really, just the straight out VPS like no other. We don’t map PCI devices to VPSes etc. It really is just an OS on a disk with a memory allocation.

 

Considering you have both, would you be able to give a brief advantages/disadvantages between using OpenVZ and Xen? I have been considering OpenVZ as well as Xen and Xen was looking a little better on the IO performance side.

 

Thing is, we would like to be able to take advantage of the fact the CPU can handle 64bit and would like to run a 64bit Xen host along with 64bit VPSes. I am not sure if Xen can do this or not, nor whether OpenVZ can either.

 

If you look at my original post to the mailing list, we are considering the switchover because of new hardware/newer OS.

I have both and Virtuozzo has less overhead then Xen.  It is the reverse. I use XEN because I need to virtualize Windows along with Linux. But rest assured, OpenVZ and Virtuozzo are one or several steps ahead. The management tools are far more sophisticated in Virtuozzo and the support is amazing, it cannot be compared.

Hi Rob,

 

Basically there’s 2 reasons why I’m looking at Xen:

 

1. Cost of licencing for Virtuozzo which is based on how many CPUs etc.

2. Xen has better IO performance compared to Virtuozzo. It’s been shown on a few forums that Xen can have 3 times the disk IO performance.

 

Does anyone have any answers to my original questions?

 

Regards,

Alan

I'm curious about your shift from Virtuozzo: is that because you needed

something other than Virtuozzo does? or because Virtuozzo proved to be

ineffective in some way?

 

I'm asking because I'm being urged to work with Virtuozzo, and wanted to

know if there were some pitfalls in using it that were evident in

people's experiences with it.

 

Appreciate any thoughts you can share.
