The silly mistake that always gets me is I forget to put the .img extension on the initrd file, be careful when running mkinitrd that the exact command is: # mkinitrd -f --preload=pciback /boot/initrd-$(uname -r).img $(uname -r) You can remove the pciback stuff from grub.conf, but make sure the modprobe.conf options are there prior to running mkinitrd. -Ross ----- Original Message ----- From: centos-virt-bounces at centos.org <centos-virt-bounces at centos.org> To: Discussion about the virtualization on CentOS <centos-virt at centos.org> Sent: Thu Apr 17 17:03:07 2008 Subject: RE: [CentOS-virt] Xen List >Here's an example using my sound card. > >/etc/modprobe.conf: >options pciback hide=(00:10.1) ># If you aren't preloading pciback in the initrd uncomment the next line >#install snd-hda-intel /usr/sbin/modprobe pciback; /sbin/modprobe --first-time --ignore-install snd-hda-intel > >To preload pciback in initrd: > ># mkinitrd -f --preload=pciback /etc/initrd-$(uname -r).img $(uname -r) > >That should do it. Ok, this is where I got messed up (No grub line :)). I originally had the rpmforge sk98ln rpm installed to make this realtek nic work before I tried this, then using this procedure which I followed to a "t" didn't mask the device from Dom0? It loaded the driver and setup the nic? I know I had the pci slot number right. I thought the initrd was wrong, so I looked through grub and looked at what it loaded, then checked the timestamp of the one I made with that command and it was consistent? I assume something still wasn't right with my mkinitrd, it completed with zero verbosity, mayeb I should try to use -v and see what happens. Any ideas?
