Paul -- thanks for the clarifications. Hopefully somebody from the Meego community will be able to respond further to the specific RT capabilities (or lack thereof) in Meego 1.1. > configuring your system for RT usage has ABSOLUTELY ZERO to do with > the presence or absence of the RT patch.

True -- I use them currently with a stock fedora kernel (which is where I run my KVMs out of). This functions adequately for most low-channel purposes using tools like jack, ardour and qtractor -- as long as I'm not running certain other applications concurrently (such as a web browser doing heavy javascript processing, like browsing gmail). However, "rtirq" is one such configuration change which does have something to do with the presence of the RT patch, and appears to be in inequality with "absolutely zero." especially the all-capitalized variety. :-) ... Regarding virtualization and multimedia devices access, Fedora 14 claims "Easier virtualization for end users. From the creators of KVM comes Spice (Simple Protocol for Independent Computing Environments). This framework allows end-users to enjoy the features they enjoy, such as accelerated 2D graphics, encryption, and audio playing and recording, all while working in a virtualized environment" ... ///// ///// ///// ///// ///// The other big news is Spice, the Simple Protocol for Independent Computing Environments. Spice is part of Red Hat's Qumranet acquisition[2], which also brought the now standard KVM virtualization to both RHEL and Fedora. The goal of the Spice project is to improve remote access to QEMU virtual machines. For those running Windows clients in a virtual machine Spice includes a few Windows helpers right out of the box including a video driver, an agent for performing operations inside the guest system and virtio serial drivers for talking to the agent. Although Spice has been available in the Yum repos since Fedora 12, the new tools make getting Spice up and running much easier and should be good news for those with multiple virtual machines to manage. The cloud gets an update, too. Fedora 14 will mark the first time that Fedora will concurrently release all its usual spins and a new Amazon EC2 image. That's great news for those using Amazon's cloud hosting to run Fedora machines." ↑ http://lists.fedoraproject.org/pipermail/marketing/2010-September/013438.html ↑ http://www.redhat.com/about/news/prarchive/2009/spice-os.html ↑ http://www.channelregister.co.uk/2010/09/29/fedora_14_beta_review/ ///// ///// ///// ///// ///// -- Niels http://nielsmayer.com PS: Potentially answering some of my previous questions: app-emulation/qemu-kvm-spice:alsa, app-emulation/qemu-kvm-spice:pulseaudio, app-emulation/qemu-kvm-spice:esd ...
