Live CD

The installation process is pretty staightforward. Boot a live image and run


This should take care of the most basic installation tasks and will leave us with a bootable Void Linux installation.

Xen DomU

One can also install Void Linux as a Xen DomU. The ROOTFS images can be used for that:

lvcreate -L 2G -n void-root vg0
mkfs.ext4 /dev/vg0/void-root
tune2fs -e remount-ro -c 20 -i 6m /dev/vg0/void-root
mount -t ext4 /dev/vg0/void-root /mnt/disk/

tar -C /mnt/disk/ -xvJf void-x86_64-musl-ROOTFS*.tar.xz

The tricky part was how to get the correct initrd in place so that we can actually boot the domain.

for d in /dev /proc /sys; do mount --bind ${d} /mnt/disk/${d}; done
chroot /mnt/disk/

Now, in the chroot, we'll install a kernel and tools to generate an initrd:

% xbps-install linux5.6 cpio dracut
% ls -d /boot/vm* /lib/modules/*                                                                                                                                                                             
/boot/vmlinuz-5.6.6_1  /lib/modules/5.6.6_1

% mkinitrd /boot/initramfs-5.6.6_1

With these files now present, we can exit the chroot, copy both kernel and initrd and configure our domain accordingly:

$ grep -A3 ^type /etc/xen/tor.cfg 
type    = "pvh"
kernel  = "/var/local/vm/tor/vmlinuz"
ramdisk = "/var/local/vm/tor/initramfs"
extra   = "root=/dev/xvda rootfstype=ext4 console=hvc0 nomodeset"

Post Install

They even have an article on Post Installation tasks. Let's install and configure some packages:

xbps-install -Sv acpi base-system checksec cryptsetup grub haveged lm_sensors pv pwgen spectre-meltdown-checker thermald wget

Enable some services - adjust as needed:

for s in acpid haveged sshd thermald; do ln -s /etc/sv/${s} /var/service/; done

After a service is enabled, it should already be running:

$ sv status acpid haveged sshd thermald
run: acpid: (pid 866) 1s
run: haveged: (pid 2823) 1s
run: sshd: (pid 862) 2s
down: thermald: 0s, normally up, want up


As Void Linux is implemented as a rolling release, we can use xbps (X Binary Package System) to update the system:

xbps-install --sync --update --verbose

For some reason Void Linux appears to leave old kernel images and modules in place, but provides a tool to remove them too:

$ vkpurge list 

$ uname -r

$ vkpurge rm all
