[Libguestfs] IRC question: How to install a kernel module using virt-customize

21:26 < ibravo> hello. I'm trying to install a kernel module to a VM Image. How can I do this using virt-customize? Please stay in the IRC channel after asking questions! Anyway, the answer depends on the guest and the kernel module. For example if it was a Debian guest and you wanted to install the ZFS dkms package, then following the instructions here: http://zfsonlinux.org/debian.html you could do this: $ wget http://archive.zfsonlinux.org/debian/pool/main/z/zfsonlinux/zfsonlinux_6_... $ virt-customize -a debian-8.img \ --install lsb-release \ --upload zfsonlinux_6_all.deb:/tmp \ --run-command 'dpkg -i /tmp/zfsonlinux_6_all.deb' \ --update \ --install debian-zfs [ 0.0] Examining the guest ... [ 15.2] Setting a random seed [ 15.2] Installing packages: lsb-release [ 26.6] Uploading: zfsonlinux_6_all.deb to /tmp [ 26.6] Running: dpkg -i /tmp/zfsonlinux_6_all.deb [ 28.4] Updating core packages [ 219.9] Installing packages: debian-zfs [ 540.9] Finishing off (As you can see, it takes ages to run because it actually compiles the kernel module.) When booted, this guest has the zfs.ko kmod installed (and the tools). It's hard to give general instructions since almost any conceivable kernel module would need to be compiled, and that would inevitably involve dkms/akmod, which means using an out-of-tree/out-of-distro install method similar to the one above.
