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? -- Bye, Fernando Maciel Souto Maior fernando@xxxxxxxxxxxxx http://www.araujo.com.br +55+31 3270-5886 LPIC/1 # 31908 AVISO------------------------------------------------------------- Esta mensagem pode conter informacao confidencial ou privilegiada.
