xen (para) virtualisation

hi as I am about to install Cloudmin with Xen on a new server I have this question.
Is the default setup using para-virtualisation or virtualisation?

I like it to be para-virtualisation as I have understood that the layer is thinner/more transparent and the instances can talk directly to the hardware or at least more so then using virtualisation, making the vps run faster.

Also I thought that Xen didn't need a OS, but then the solution is Citrix or to use VMware esxi.
I'm going for a centos 64bit install with the Xen kernel. Am I right to do it this way?

Closed (works as designed)


The default is para-virtualization, as that is all that is needed for running Linux, which is what most Cloudmin users do. There's no support yet for running operating systems like Windows or FreeBSD that need full virtualization ..

yes the other thread is duplicate but I couldnt find this thread any more (oddly enough) so I made a new one, I think now it had to do with status set to By Design).
I found this one by searching under duplicates..

Ok .. so do you have any other questions about Cloudmin and (para-)virtualization ?

I think Im ready to go ahead with installation end of the week,
One thing I was interested in is as of Xen 3.0 it is possible to run unmodified windows xp as a guest when the CPU had VT (i read in the wiki)
is this so and will cloudmin support this in the future?

I think this is possible, but I haven't tried it myself. Cloudmin doesn't support real management of Windows guests though..
