Three more thins I have some doubts about : 1- the guest : shall I mount it at rootfs in /dahlia or /machine/dahlia ? I have tried both. 2- in my dahlia.xml :
<partition>/machine/dahlia</partition>
Is that correct for a /dahlia OR /machine/dahlia guest mount point ?
I do have any .scope unit file (normal ?) neither
/etc/systemd/system/dahlia.service ?
TY again Tom for your support
