Why use Xen/OpenSolaris when you have Citrix XenServer
This is a very leading questions, but its only now I am looking into Virtualization for real. I am an OpenSolaris fan but I have been talking with someone else who has being playing with Citrix XenServer Express Edition (the free version). Forgetting about open source and cost issues - which are very important - I have a couple of questions: - All the diagrams I see show Xen layer above the hardware and then each O/S above it including the Dom0, but my understand is that really it should be the (hardware) then (Operating System+Xen) and then (other O/S) above that? - If I reboot Dom0 (OpenSolaris) then all the other DomU (guests) get rebooted as well? - My understanding is that Citrix XenServer is a cut down version of linux + Xen, which means that it should require less patching/rebooting than let say OpenSolaris version? - Is there any way to have a Cut Down version OpenSolaris / Xen, so that you only had installed the bare minimum software running Xen, to cut down on rebooting. Is that what is planned with "xVM Server" http://openxvm.org/learn.html software? Thanks again, Andrew PS. Anyway, just installed Windows 2003 (Dom U) on my OpenSolaris box and it looking good.
