[Xen-users] General Xen setup questions
Hello everyone!
I am setting up a couple of Xen servers for the first time and I have a
couple of questions. Also, as this is my first attempt at using Xen, if
you spot anything in my descriptions that looks to be a stupid thing to
do, please let me know.
As an overview, I will be running 4-5 domU machines on 2 dom0's . The
dom0 machines will be doing nothing but managing the domU machines. I
will be using an iSCSI SAN for the storage on my domU machines. All
OS's will be FC5.
I have not yet decided whether to put my domU OS's on physical
partitions or on the SAN. I am leaning toward using the SAN, as that
will give me the most flexibility and make live migrations easier. Thoughts?
Anyone know which will preform better: Mapping the iSCSI drives to dom0
and assigning them to each domU as a phy (such as /dev/sda) or mapping
them directly on each domU?
I will have 4GB of physical RAM per physical server. How much of that
should I reserve for the dom0's, keeping in mind that they will not be
running any apps of their own, just managing the domU's?
Thanks!

UNIX was not designed to stop you from doing stupid things, because that
would also stop you from doing clever things.
