Dear All, Hello, this is my first message in this and any mailing-list. The problem is as follows: I have an old PC (P3 550MHz, 384MB of RAM and 20GB of disk space) the issue is that with the Linux´s original kernel I detect all the Hardware correctly. I followed an installation guide from www.howtoforge.com for installed XEN 3.1.0 in Debian etch, when I finished installing the new kernel and booting, the system detects only 350MB of RAM, is that correct? I think that is correct to be subtracted the ram I assign to my VM when they are activated, but, is it correct to lose these 34MB without doing anything? If I run a Xen-list command, it tells me that the dom0 is consuming 200MB of ram, is that correct? Beyond this I want to mount a small network with them, all within the same physical PC with 3 VM, one that is my internet firewall (xen1), another one in the DMZ (xen2) and a third one in my lan (xen3) . The phisical PC has 2 nics, the question is how do I allow the "xen1" VM to get the DHCP address from my ISP, and not to get the public IP in my dom0. And how do I specifically add a single virtual Nic to "xen1" VM to be allowed to generate the DMZ with the "xen2" VM. Thank you very much. Greetings. Pablo.- -- View this message in context: http://www.nabble.com/Xen-Questions-tp18175548p18175548.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, does anyone know something about this? I have another problem. When a virtual is been fully used, 100% RAM, the dom0 RAM is consumed, but, when the virtual finish what it is doing, the RAM remains allocated, and it is not release, so, the dom0 has very little mem to work with and the performance is very low.
