|
||||
------------------------------
|
||||
|
||||
To create a new virtual machine image, run
|
||||
$> sudo ./create.sh
|
||||
|
||||
The creation is influenced by the following environment variables:
|
||||
$> ./pvmbootstrap.sh [path to image] [arch]
|
||||
|
||||
ARCH - the target architecture of the image. default: armv7h
|
||||
where arch is one of the supported parabola arches, which are currently:
|
||||
|
||||
SIZE - the size of the root image. default: 64GiB
|
||||
official: [ i686, x86_64, armv7h ]
|
||||
unofficial: [ ppc64le, riscv64 ]
|
||||
|
||||
MIRROR - the mirror used to pacstrap the image, anything valid in a `Server =`
|
||||
line can go here.
|
||||
default: https://redirector.parabola.nu/\$repo/os/\$arch}
|
||||
the script will attempt to bootstrap a virtual machine of the selected
|
||||
archituecture in the output file specified. If the output file already exists,
|
||||
the script will emit a warning and ask for confirmation to proceed.
|
||||
|
||||
The created images are stored in the build/ directory.
|
||||
the creation can be influenced by providing one or more of the following
|
||||
arguments to pvmbootstrap.sh:
|
||||
|
||||
-s size -- set the size of the created VM image (default: 64G)
|
||||
-M mirror -- set the mirror to fetch packages from
|
||||
(default: https://repo.parabola.nu/$repo/os/$arch)
|
||||
|
||||
the created machine images should be bootable using pvmboot.sh
