RE: [Xen-users] Guide for setting up Xen servers to share an array?
Just a note – you do not need identical machines to do a XEN
cluster. You can do live migrations with shared storage between servers of
disparate memory, CPU, etc.

Subject: [Xen-users] Guide for setting up Xen servers to share an array?
I need to setup 2 Xen servers to share the same external
array drive so I can do live migration back and forth.
I can get the live migration working between the servers
without the array but when you migrate the guest over it does not migrate the
image and all you have is the guest system running in memory.
What I need to do is have the updated images on both boxes
so when I do a migration or need to start up the guest on the other xen box
the guest is the most current system.
I have thought about FTP'ing the image and config files to
the secondary host once an hour but that is alot of transfers and is not
practical.
I then decided the best way is to have one drive on an
array and have them both pointed to it that way if there is an issue with the
primary host server I can just stop the guest OS on that server and them
start it on the secondary. This would also allow me to get all the guests
running on the secondary if the primary host dies completely.
Has anyone done this or know of a guide to do this? I was
going to TRY to do a cluster but the 2 host boxes have different CPU's and
memory amounts. In the future I will have identical boxes to use.
