Remus wiki page updated

[Pasi Kärkkäinen]

Hello,

http://wiki.xensource.com/xenwiki/Remus

I just updated that wiki page with some info to avoid confusion,
and also linked that page to a couple of other wiki pages.

Let us know if there's something missing or wrong on that page.

Brendan: I wrote "Shared storage" to the requirements on the wiki, 
since it's listed on the first paragraph on the Remus docs,
but later on it seems Remus doesn't require shared storage? 

Is this correct? 

Thanks!

Remus doesn't expect shared storage -- in fact, it requires distinct
disk images for correct buffering of speculative disk writes.

I see what you're referring to in the documentation: "So, the first
thing you should do is make sure that you can live-migrate your VM (in
this mode your guest's disk must be available through shared storage
on both the primary and backup)"

That sentence is only meant to apply to live migration (xm migrate
--live). I'll clarify the documentation about that.

Thanks very much for updating the wiki page!

Last I checked you could not run HVM guests with PV drivers. If that's
still the case it should certainly be mentioned.
