Cannot install YunoHost in QEMU

My YunoHost server

Hardware: Intel G5420, 16 GB RAM, NVME-SSD
YunoHost version: yunohost-buster-4.1.6-amd64-stable.iso
I have access to my server : Through SSH as well as using virt-manager
special context : yes:
I tried installing yunohost in a QEMU/KVM-VM
I tried using 2 cores and 2048 MB RAM for the VM. The boot-disc is a 200 GB large qcow image on an NVME-SSD and I wanted to mount a folder via QEMU later as a “data partition”. If that’s inappropriate, please recommend better values/approaches.

Description of my issue

The default installer cannot install grub on the disc. When trying to run that step of the installation the error message “GRUB konnte nicht auf /dev/sda installiert werden.”

This strikes me as weird because when launching a shell and running df -h there’s no /dev/sda-disk. Only a /dev/vda-disk. The same issue would arise if you tried to install yunohost on a bare metal machine that is supposed to use an NVME-drive as boot-drive. There the boot drive would be referred to as /dev/nvme0n1.

How can I ensure that grub is installed on /dev/vda?

How can I ensure that no other issues arise later related to /dev/sda apparently being a hardcoded value?

Also the fact that I’m not able to configure the partitioning (combined with the hardcoded disk path) leads me to believe that yunohost tries to install everything on a non-existing disk. Is this the case?

I will let actual experts answer you regarding the VM issues.

Meanwhile, what I suggest you to do is installing Debian 10 first, set your mount points as you wish (YunoHost apps are generally stored in /home, /opt, and /var/www), and then install YunoHost on top of it.

Here is the related documentation page: https://yunohost.org/install/hardware:vps_debian
You should create the mount points before running curl https://install.yunohost.org | bash .

Didn’t know, that you could just install yunohost on top of an already installed debian, thank you very much! I’ll try and see if it works.
