[Fedora-xen] F15 kernel Xen support missing PCI passthrough?
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.
