Modify the installer for Proxmox PVE 8.1.2 to accept parameters to run unattened. Note: This also works on 8.2, but you need to modify the files as described in the build custom initrd.img. Files included on this site is for 8.1.2.

Limitations

• No software RAID setup
• My perl skills :-)

Extra kernel parameters:

• px_dns=<dns ip>
• px_domain=<domain>
• px_cidr=<server ip/subnet>
• px_gw=<gateway ip>
• px_keymap=<keyboard>
• px_time_zone=<timezone>
• px_country=<country code>
• px_hostname=<hostname>
• px_mail=<mail address>
• px_target_hd=<hd>
• px_mngmt_nic=<nic>
• px_mngmt_nic_id=<nic id>
• px_password=<root password>
• px_unattend=<yes/no>

Example from grub.cfg

• linux /boot/linux26 ro ramdisk_size=16777216 rw splash=verbose vga=788 px_dns=10.10.10.100 px_domain=mgmt.domain.com px_cidr=10.10.10.10/24 px_gw=10.10.10.1 px_keymap=dk px_time_zone=Europe/Copenhagen px_country=dk px_hostname=pv202 px_mail=[email protected] px_target_hd=/dev/sda px_mngmt_nic=eno5np0 px_mngmt_nic_id=2 px_password=SuperSecret px_unattend=yes

Findings:

• Using grubx64.efi from the Proxmox iso gave me an "out of memory" error when loading initrd so I used grubx64.efi from the latest Ubuntu distro.
• Diable TPM in BIOS
• Add "rmmod tpm" to grub.cfg
