I posted this page on the wiki last week, which is a feature we intend to implement for Fedora 12: http://fedoraproject.org/wiki/Features/Hostinfo Any comments? Rich. "Allow a virtual machine to see information and statistics from the host operating system, under narrow and strictly controlled conditions and only at the discretion of the host administrator. Detailed Description Allow a virtual machine to look at host information (such as number of physical, not just virtual CPUs), and statistics like the load on the host. Users have asked for this primarily as a diagnostic tool -- for example, poor performance of a virtual machine might be caused by excessive load on the host. Normally we try to isolate virtual machines from accessing any such details from the host, and there are very good reasons for that too, such as security of the host, commercial confidentiality, and the privacy of other virtual machines running on the host. As a result, at the moment there is no mechanism for accessing host information. We propose to add a feature which allows the host administrator, at their discretion, and only of limited data to limited virtual machines, to export host information and statistics to virtual machines. Administrators will need to: * explicitly enable this feature, * select the virtual machines and/or data they wish to be seen in guests, * select the frequency that guests can ask for data. The mechanism will be a daemon running on the host which collects the statistics (see below for what). The information will be exported to guests over a spare (virtual) serial port or through the qemu/kvm vmchannel feature, whichever is available. Guests will request information by sending a plain text command to the serial port, and will receive information in the form of a simple, plain text message. No special drivers or software are required by the guest. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler.
