Hello,

First thank you very much for *XCP 1.1*, the *vmvnc* script and helpful 
hints from both xen-lists!

I hope the description below "How to create and install CentOS PVMs with 
xe CLI on XCP 1.1" will be helpful for first steps without XenCenter (as 
it doesn't run on Linux yet). Installation of PVM for ubuntu 11.10 
server is very similar.

I strongly suggest to read documentation of XenServer 5.6 sp2 
(reference.pdf and guest.pdf) for better understanding.

Enjoy and feel free to add it to xen-wiki or to documentation if you 
find it useful .

regards, Mark

Re: Docs: How to create and install CentOS PVMs with xe CLI on XCP 1.1

Hello, 

As you've obtained "Local \ LVM \ SR \ DB-VM-pool." 

You used lvcreate then "xe sr-create"?

*SOLUTION:* 
I have modified the logical volume, then its size Resize to finally create
the "Local  LVM SR DB-VM-pool."

*NEW PROBLEM:* 
He has been a new problem, in the step of giving confirmation to write the
changes to the partition where you are installing centos, vncviewer
disconnects and I can not reconnect.

Are you sure that the version 6 of the centos6 can be virtualized in the XCP
1.1??

You have completed the installation?
