to-be done

• Memory backing needs to be added:

<domain type="kvm">
[...]
    <memoryBacking>
        <source type="memfb"/>
        <access mode="shared/>"
    </memoryBacking>
[...]
</domain>    

• Then a a directory can be shared using the following definition:

<domain type="kvm">
[...]
    <devices>
    [...]
        <filesystem type="mount" accessmode="passthrough">
            <driver type="virtiofs"/>
            <source dir="/mnt/"> # Host directory to be shared with the guest
            <target dir="/mnt"/> # Directory on the guest
        </filesystem>
    [...]
    </devices>
[...]
</domain>
