Hi guys, apologies for posting on xen mailing list earlier, I have fc14 running kernel-2.6.35.13-91.fc14.x86_64. I did $ yum install xen I would like to compile xend modules with this, I did steps according to http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial $ make -j4 bzImage && make -j4 modules $ make modules_install $ depmod 2.6.32.40 ( its here where I later run into problems as I do not have the right kernel to use, maybe?) $ cp -a arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.40 $ cp -a System.map /boot/System.map-2.6.32.40 $ cp -a .config /boot/config-2.6.32.40 $ cd /boot/ $ dracut initramfs-2.6.35.13-91.fc14.x86_64.img 2.6.32.40 Will not override existing initramfs (/boot/initramfs-2.6.35.13-91.fc14.x86_64.img) without --force $rpm -qa | grep xen xen-runtime-4.0.1-7.fc14.x86_64 xen-licenses-4.0.1-7.fc14.x86_64 xen-hypervisor-4.0.1-7.fc14.x86_64 xen-libs-4.0.1-7.fc14.x86_64 $ is there something I am missing? Please point me to the right direction. I will do the rest Thank you in advance

Has anyone else had trouble starting xend when SELinux is enforcing the targeted policy on the various test releases of Fedora 15? I just submitted a bug report at: https://bugzilla.redhat.com/show_bug.cgi?id=706987 -- Mike :wq

2.6.32 dom0 kernel
by M A Young 18 May '11

18 May '11

I have built a new 2.6.32 kernel, based on my Fedora 12 kernels, but with updates to the latest 2.6.32 kernel patch (2.6.32.34 with the extra patch to make it equivalent to 2.6.32.35) and latest xen next-2.6.32 patch. It was built on Fedora 13. It is available (temporarily) from koji at http://koji.fedoraproject.org/koji/taskinfo?taskID=2940510 and from my repository http://repos.fedorapeople.org/repos/myoung/dom0-kernel/ Michael Young

How to use xen-pciback
by Robin Axelsson 09 May '11

09 May '11

Hi, I have compiled Jeremy's kernel on Fedora 14 and it turned out that xen-pciback is compiled into the kernel as a module. So I made a "xen-pciback.conf" file in /etc/modprobe.d. The problem is that I have to get modprobe to load before the drivers to the PCI devices I want to hide are loaded. So my question is how do I locate the drivers and find the points in the boot scripts where I can put the modprobe so that it is loaded before them? I tried lsmod and modinfo but they don't give much information. I only managed to find the driver for the Intel EXPI9400PT adapter e1000e. I want to hide the graphics adapter (Radeon 5450), Two USB2.0 ports, the Intel adapter, the USB3.0 controller and the Audio device, their assignments on machine are as follows: pci_0000_00_02_0 (GPU) pci_0000_00_12_0 (USB 2.0 should give 2 ports) pci_0000_00_14_2 (Audio device) pci_0000_00_0a_0 (Intel Adapter) pci_0000_00_09_0 (USB 3.0 Interface) but the question is where can I locate their drivers and how can I tap into the boot sequence so that the xen-pciback driver is loaded beforehand? The page http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_m… gives no information about this. It mentions something about "install skge ... " but it doesn't say where this line is to be put and how you figure out that skge is the driver to be disabled. I have set up the machine to init level 3 in the /etc/inittab (my install of F14 have no upstart targets). The xen-pciback module seems to be working. Something is wrong with the onboard sound chip. No drivers have ever successfully initiated it, neither in Windows nor Linux. So it is marked as an assignable device when looking it up with xm. Regards Robin.

How to compile Jeremy's dom0 pvops kernel (2.6.32.x) on Fedora 15
by Robin Axelsson 03 May '11

03 May '11

Hi, I'm trying to compile Jeremy's paravirt_ops kernel on Fedora 15 using the following tutorial: http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial but in the compilation process I get error messages that some .c and .h files are missing. I couldn't locate the packages that would house these files for Fedora 15 so I wonder how to compile it for F15. I want to use Jeremy's kernel because I need dom0 pciback drivers for using VGAPassthrough and PCIpassthrough. Regards Robin.
