    How to add a swap drive to your system, in this case I did this for a virtual machine (qemu) running Arch Linux.

    See at the bottom for information about the virtual drive for qemu.

    List current available to system disks:

    sudo blkid

    List all disks:

    sudo lsblk

    Format as swap:

    sudo mkswap /dev/vdb

    gives back the UUID

    Now the new swap disk will be shown when executing this again:

    sudo blkid

    (also give the UUID)

    Take the UUID from above and add an entry in /etc/fstab like this:

    echo "UUID=56445300-90f5-40b4-860b-99037d0e8aad none swap sw 0 0" |sudo tee -a /etc/fstab

    Actiate available swap disks, ie. from fstab or on GPT volume. 

    sudo swapon -a

    Check the swap is available now:

    sudo swapon --show

    The qemu image I created as „raw“, VirtIO and set the cache mode to „writeback“, this should be fine for swap while being fast too. See explanation here and here.

    I also looked at this information about how to add a swap disk.

    As always, give me your feedback, I will add information that can help in the future.
