RE: [Xen-users] New to Xen

[Matej Zary <zary@xxxxxxxxx>]

Hello,


first, to clear some possible confusion, these are separate "products":

Xen - open source type 1 hypervisor, usually used with some kind of Linux 
distribution as "management" base
Citrix XenServer - complete "plug&play" commercial product ("virtualization 
appliance") with free and paid versions available
XCP (Xen Cloud Platform - opensource "virtualization appliance" partly almost 
"the same" as the Citrix XenServer (e.g. doesn't have the graphical XenCenter 
front-end, newer xen kernel etc.)

Second one and third one use Xen hypervisor, but they are "broader" than just 
the hypervisor and the basic tools - they come with own "management base", 
different control interface etc. 

Regarding the Citrix XenServer Essentials (paid version of Citrix XenServer) - 
it's better to ask on their official forums - 
http://forums.citrix.com/category.jspa?categoryID=101.

Regards

Matej

Subject: [Xen-users] New to Xen

I'm new to Xen, although have plenty of experience with VMware products. Can 
anyone answer these specific questions, without me having to research the 
arcane nature of the Xen Server product.

 

1              Can an assortment of .vmdk ESXi OS's be converted without using 
the Windows utility? For example, is there one built in the latest bare metal 
XenServer Essentials so by just copying the .vmdk files using scp from the 
VMware server directly to the XenServer the script will convert them one after 
another by using a script overnight?

2              Does XenServer Essentials have a ability for timed backups? Does 
the OS have to be shut down, or can it run during the backups? I saw the 
metadata backup, but that's only a part of the puzzle.

3              Can XenServer Essentials mount an external USB or eSATA drive 
for backup purposes?

4              Has anyone written a blog post or anything describing the 
different flavors of XenServer Essentials without resorting to jargon, that 
only means something once you know the product?

5              What's the difference between the OpenSource Xen Server (v4?) 
and the Citrix XenServer Essentials?

6              How many CPU cores does XenServer Essentials support. VMware 
ESXi supports 6.

7              Anything else a newbie needs to know.

 

 

Thanks for your help,
