NixOS container (LXC) on Proxmox Virtual Environment 7

GUI CLI
find the (a current) NixOS template

for example for 21.05

the link for the latest (daily) tarball for a container (of 21.05) is

https://hydra.nixos.org/job/nixos/release-21.05/nixos.containerTarball.x86_64-linux/latest/download-by-type/file/system-tarball
download the NixOS template
  • (if you want to switch to the Storage View and) go to one of your nodes where you can (find and) store CT Templates.
  • choose the Download from URL button

going to the folder where all the templates for Promox Virtual Environment are stored

cd /mnt/pve/cephfs/template/cache

downloading the NixOS template file

wget -c https://hydra.nixos.org/job/nixos/release-21.05/nixos.containerTarball.x86_64-linux/latest/download-by-type/file/system-tarball

(optional you should) move the downloaded NixOS template file to a nicer (more individual) file name

mv system-tarball nixos-21.05_2021-10-10.tar.xz

(optional you can) going back

cd -
create a (first) new NixOS container with Proxmox Virtual Environment
pct create …


pct create 1000 --arch amd64 --description nixos-template cephfs:vztmpl/nixos-21.05_2021-10-10.tar.xz --ostype unmanaged --net0 name=eth0 --storage storage --unprivileged 1




(optional you can) check the (pve) lxc config file (and it should look like something like the following)
less /etc/pve/lxc/1000.conf



arch: amd64
#cmode: shell
#cores: 1
#features: nesting=1
hostname: CT1000
memory: 1024
net0: name=eth0,bridge=vmbr1,hwaddr=E6:8B:60:E0:19:4C,ip=dhcp,type=veth
ostype: unmanaged
rootfs: storage:vm-1000-disk-0,size=4G
swap: 512
unprivileged: 1






customize the individual Proxmox Virtual Environment container configuration for NixOS





sync_wait: 36 An error occurred in another process (expected sequence number 7)
__lxc_start: 2073 Failed to spawn container "1000"
TASK ERROR: startup for container '1000' failed





editing the specific (pve) lxc config file (to a option for lxc.init.cmd)



nano /etc/pve/lxc/1000.conf




lxc.init.cmd: /init






(configure the available (virtual) network device for the Proxmox Virtual Environment container)










(activate nesting for NixOS in the Proxmox Virtual Environment container)







(optional you can) check the (pve) lxc config file (and it should look like something like the following)
less /etc/pve/lxc/1000.conf



arch: amd64

features: nesting=1

ostype: unmanaged
rootfs: storage:vm-1000-disk-0,size=4G
swap: 512
unprivileged: 1






customize the (pve) lxc startup setup routine





run_buffer: 316 Script exited with status 1
lxc_init: 816 Failed to run lxc.hook.pre-start for container "1000"
__lxc_start: 2007 Failed to initialize container "1000"
TASK ERROR: startup for container '1000' failed

sub unified_cgroupv2_support {
    my ($self) = @_;




    return if !$self->{plugin}; # unmanaged



    $self->protected_call(sub { $self->{plugin}->unified_cgroupv2_support() });
}
