Re: [Xen-users] Xen properties

Probably best to avoid cross posting of general questions :)

Xen is not Virtuozzo. If you allocate a resource to a guest, that
resource is for the exclusive use of that guest, unless you're using
some kind of network block device and shared file system.

However you want to divvy up the resources of the host node (dom-0) and
export any network attached storage present.

I think reading the Xen documentation would help you more on the basics
than asking the list :)

You can't turn Xen into virtuozzo. You can't turn lead into gold (or
gold into lead). I fear, however the efforts extolled on both endeavors
will be disturbingly equal.

There is a credit scheduler available in unstable that is quite nice and
preferred if you want to use Xen to re-sell dom-u's (which looks like
your purpose due to the questions).

There is no practical way to make Xen more like Virtuozzo, you can *not*
over-sell resources. Any attempts to do so simply retards Xen. Some have
reported success with OpenVZ running as a fully virtualized Xen guest,
but no real feedback on performance.

You really need to read up on Xen Enterprise, www.xensource.com is your
best bet with plenty of FAQ's regarding XenEnt as well as a handy link
to the wiki :)
