should be good to go. The only thing to do at install time is to make
sure you select “ext” local storage rather than LVHD. It
might also be known as “XenDesktop-optimized” or “Intellicache”
depending on where you’re looking. We realized the other day that
we forgot to document that step and I don’t know if John’s done it

you’re building on an NFS share though, that often screws up the
permissions. You could have root-squashing turned on, and then every file
that’s supposed to be owned by root is owned by an unprivileged user
instead. It wouldn’t surprise me that this freaks out the init

<p class=MsoNormal>Wether on XenServer or XCP, I always seem to hit the same
issue. When the ALLINONE VM is fired up, it shuts down after a few seconds with
a kernel panic ( as seen here: <a href="http://imgur.com/i85fC">http://imgur.com/i85fC</a>).
The same issue occurs with the domU_multi scripts too.<o:p></o:p></p>
