This is an Athlon MB, with a sis964L. I have changed memory because I was using a generic AMD only stick but the problem still occurs. I have attached the dom0 config file and my hwinfo results if they can be useful. I would like to know if there can be a resolution to the problem or do I have to purchase another motherboard. My last problem was never resolved. (it concerned my not being to mount swap within the domains even though the device would show in the domU''s proc directory. Yes the partition was marked as swap and it is a lvm backed space. I haven''t tried with a vbd file. I''m afraid that if there is a requirement for memory which exceeds physical mem, the machine will fail. Badiane __________________________________________________ Do You Yahoo!? Tired of spam?
