To prepare a virtual machine disk, as `sudo` user with `nix` installed, run in `..`:
|
||||
```bash
|
||||
nix run '.#example' -- sudo install-system /home/$(id -un)/vm/disks/example.img && sudo chown $(id -un): /home/$(id -un)/vm/disks/example.img
|
||||
nix run '.#example-raidz' -- sudo install-system /tmp/nixos-main.img:raidz1=/tmp/nixos-rz1.img:raidz2=/tmp/nixos-rz2.img:raidz3=/tmp/nixos-rz3.img
|
||||
nix run '.#example' -- sudo install-system /home/$(id -un)/vm/disks/example/
|
||||
( sudo chown $(id -un): /home/$(id -un)/vm/disks/example/* )
|
||||
nix run '.#example-raidz' -- sudo install-system /tmp/nixos-example-raidz/
|
||||
```
|
||||
Then to boot the system in a qemu VM with KVM:
|
||||
```bash
|
||||
nix run '.#example' -- sudo run-qemu /home/$(id -un)/vm/disks/example.img
|
||||
nix run '.#example' -- sudo run-qemu /home/$(id -un)/vm/disks/example/
|
||||
```
|
||||
Or as user with vBox access, run this and use the UI or the printed commands:
|
||||
```bash
|
||||
nix run '.#example' -- register-vbox /home/$(id -un)/vm/disks/example.img
|
||||
nix run '.#example' -- register-vbox /home/$(id -un)/vm/disks/example/primary.img
|
||||
```
|
||||
Alternative to running directly as `root` (esp. if `nix` is not installed for root), the above commands can also be run with `sudo` as additional argument before the `--`.
|
||||
Alternative to running with `sudo` (if `nix` is installed for root), the above commands can also be run as `root` without the `sudo` argument.
