    e1000e module not blacklistable?

    I want to passthrough some NICs to my domUs with xen-pciback.
    Creating /etc/modprobe.conf with the following options works for my DVB-Card:

    install ddbridge /sbin/modprobe xen-pciback ; /sbin/modprobe --first-time --ignore-install ddbridge 
    options xen-pciback hide=(0000:04:00.0)
    This does not work for the e1000e driver module.

    I used the same config, but changed ddbridge to e1000e and another time to e1000 the loading of xen-pciback was not triggerd and the NICs not available for passthrough.

    I then removed all the code above from /etc/modprobe.conf and simply put:

    blacklist e1000e
    and another time

    blacklist e1000
    in it. After reboot lsmod showed, that e1000e loaded anyway.

    After that I removed /etc/modprobe.conf and added the blacklist e1000e command to /etc/modprobe.d/blacklist.conf and another time to /etc/modprobe.d/e1000e.conf . Both times lsmod showed that e1000e was loaded after reboot.

    rmmod e1000e works without a problem.

    As blacklisting doesnt work, I think the passthrough problem is not related to the way I try to pass it through, but the fact that the e1000e does not respond to any commands at all.

    This is what I found about this:

    Although I already posted this problem over here:

    I would be very thankful for any help.

    Re: e1000e module not blacklistable?

    As mentioned in german over here:
    sudo update-initramfs -u
    worked for the "blacklist e1000e" in /etc/modprobe.conf and /etc/modprobe.d/blacklist.conf or /etc/modprobe.d/e1000e.conf. The driver is not loaded.

    Which means the file is read and processed, but when I change "blacklist e1000e" into

    install e1000e /sbin/modprobe xen-pciback ; /sbin/modprobe --first-time --ignore-install e1000e  
    options xen-pciback hide=(0000:01:00.0)
    and do another

    sudo update-initramfs -u
    No pci devices are assignable nor does lsmod show the xen-pciback driver loaded.

    My conclusion would be: This is no problem due to configuration, but something else.

    What would be the next steps I can take?
