After recently discovering 2.6.40 is secretly Kernel 3 in disguise, and includes pvops, 5 years after my last post on Fedora-Xen, I'm back. I've been running Xen on a home server for well, just over 5 years, the last three of which have been on a Centos5 dom0, in the absence of dom0 support in Fedora since FC6. I've installed a fresh machine, and can get a dom0 running in Fedora 15 using 2.6.40 and the default xen-4.1.1 packages, as well as DomU's running Centos5, Scientific Linux 6, Fedora 15 and Solaris 11, so all good there. But I've hit a snag. The Fedora kernel doesn't appear to include the xen-pciback kernel module (or indeed any module with "pciback" in its name). I use PCI Passthrough to donate a physical NIC to one of the domU's which runs the network gateway/firewall/transparent proxy etc. for the network. I've grabbed the kernel source rpm and checked out the config files, and they appear to be completely missing the XEN_PCIDEV_BACKEND flags. Being new to Fedora 15, Kernel 3 and Xen4.x all at once, is there some new trick that isn't documented online, or am I right in seeing a lack of PCI pass-through support in the Fedora kernel? My next step is to try adding the compile flags to the .config and rebuilding the kernel - but would appreciate anyone's input with more experience of the Fedora environment. Thanks, Hilton. -- xen mailing list xen@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/xen
