best Fedora virtualization
I am planning on running several virtual machines on a single host. I will have two or three Linux baeed virtual machines and one or two Windoze. I plan on using a F11 host system. I need most of these to run automatically on boot-up of the host system. It would be really nice if I could use something like the Ctl-Alt-FN to be able to access and switch between virtual machines. This needs to be stable. The machines that these virtual machines are intended to replace are often running hundreds of days between reboots. My gut feel is that the virt-manager suite might be the way to go, editting the apropriate xml files as required. I also see there is a qemu launcher and it seems to work okay. I suspect there are others as well. What tends to be the consensus here on the various virtual machine managers? Are there white papers somewhere that could give some insight?

For stability and long-term maintainability, I wonder if you've considered using RHEL or CentOS? That means you have to use Xen as the hypervisor, but if you use libvirt / virsh / virt-manager, the future upgrade path to KVM is reasonable. All tools stay the same, and you just need to run our forthcoming v2v tool on the guests (or reinstall the guests) when you upgrade.
The only one we're supporting here on Fedora<ref>http://fedoraproject.org/wiki/Virtualization</ref> is libvirt / virsh / virt-manager. Use 'virsh edit <domain>' to edit the XML for a domain. The same commands will work on RHEL / CentOS too.

I suspect this is the result of trying to use SELinux to protect everything and the mandatory access control idea that everything is disallowed except that which is explicitly permitted. But, I just do not understand what and why CD/DVD images and devices are being protected. Furthermore, when virtualization changes a file's context (including /dev/sr0), could this effect other valid usage of these files/devices? If there is no effect for other applications, then just what is protected?
