Do you really think Red Hat is going to switch back to XEN for 7 after all the work that went into finalizing 6? Of course, XEN probably will be available as an alternative, but you'll have to recompile the kernel. XEN is still listed in the F12 repo. > I don't think "switch back" is the right term, once the support is in mainline it becomes a few more builds in a sea of thousands, so it might be like PAE and non-PAE kernels. Having it allows use on additional machines, as the effort to have the capability goes down and the effort to remove or disable it goes up, the possibility goes up. There is a lot of stuff with a small user base in Fedora, and the users tend to be more diverse in their hardware (I'm being very polite here), so low effort support seems consistent with users vs. resources. And with all the effort which has gone into a better desktop, offering some solution to netbook users with no HVM has some justification. I have no crystal ball, but I own or support a fair number of netbooks. I have no thought that xen would continue as long as a custom kernel is needed, but once that's no longer the case, we'll see. >> Depending on what you run in a VM, there may be performance >> issues in xen vs >> HVM, harder to say with Linux, since it might run >> paravirtualized anyway. > > I used to run qemu and its accelerator load module with a stock kernel on a 1GHz Duron machine with 1.5 GB RAM (Its max) in Slackware, Fedora Core 3, 4, 5,& 6. It worked quite well, although, it wasn't in a server environment, just experimentation. I hated having to multi-boot to test distros or run Windows. To make a long story short, I never liked the way XEN was implemented. > -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
