Shaz,
Please, do not use html formatting for your messages to the list,
it is very dificult to sort out the tags and understand what you
mean. I, for sure, will not answer your email if you continue to
send it in html format.
1) I believe it is not a good idea to have the same root for both
domain 0 and the other domains. I would recommend to have one
pair of partitions (root+swap) for each domain but 0. I am doing
such configuration, and it helps me get more secure that way.
Also, you are mounting your root partition as RW both for domain
0 and rawhide.. you will get problems when both domains start
writing to the same partition/file.
2) For you to configure memory there is a formula:
mem(xen)+mem(dom0)+mem(dom1)+...+mem(domN)=total amount of ram
as for mem(xen) you need 64k,
as for mem(dom0) you may be using 256M,
as for mem(domN) depends on what you are using, at least 64M.
For example, if you have 512MB ram, start the dom0 with 262144
(256MB) and start every other domain with "memory = 64".
3) I also realize you did not create a swap space for your
domain rawhide. Do you believe you will never swap?
