Hi, I have a few questions. But lets start with the background:Several other virtualization technologies beside Xen do provide the possibility to get configuration information of the VM itself and the host it is running on through the /proc file system. These technologies are for example zLinux or Linux on ppc64. This feature is very important for quality of service aspects. How many physical CPU do I have? How many CPU time can I use? Other important information would the real memory and the hostname of the host machine. Basically all this information is provided by other virtualization technologies as read only values. Having a huge hosting solution with enterprise software running in virtual machines depends on these quality of service aspects. Having a black box makes debugging of performance issues impossible and thus the whole solution is not usable. Is it possible to provide such a solution with Xen (of course only if enabled in dom0 due to security reasons!) over the /proc or /sysfs?
