howto hide pci devices?
by Mike Wright 13 Mar '13

13 Mar '13

Hi all, Using 3.8.1-201.fc18.x86_64 This kernel has xen-pciback available only as a module so adding it to the kernel command line doesn't work. I added a file: /etc/modprobe.d/xen-pciback.conf that contains one line: options xen-pciback hide=(00:14.2)(01:05.1) thinking that would accomplish the same thing but it doesn't work for me. Following a reboot lspci shows the devices are still there. Am I missing a step or is recompiling the kernel the only alternative? TIA

Fresh Ubuntu Precise 12.04 i386 installation as domU in both F17 and 18 dom0 doesn't boot at all
by Roberto Fichera 07 Mar '13

Hi All, I'm trying to boot Ubuntu 12.04 LTS precise i386 as domU after a clean installation on Fedora F17 and/or F18 dom0 fully updated. Ubuntu precise was installed with virt-install --debug --connect xen:/// -n Ubuntu12LTS4 --nographics --vcpus=2 -r 1024 --arch=i686 -l http://ca.archive.ubuntu.com/ubuntu/dists/precise/main/installer-i386 --network bridge=peth0 --os-type=linux --os-variant=ubuntuprecise --disk /dev/disk/by-path/ip-10.0.0.1:3260-iscsi-iqn.2011-01.it.tekno-soft:xen.vm.Ubuntu-lun-4 After a clean instllation I'm unable to boot anymore the new domU. BTW I was able to install and boot clean the 64bits version of the same distribution. Do you have any suggestion how to solve this? Thanks in advance.
