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?
Thanks,
Hannes
