use Virtualization.framework to start linuxbased vm (amd64 for intel,arm64 for m1) support shared folder
1、edit easyVM.json file
{ "name":"ubuntu20", //you vm name
"cdrom": [], //cdrom image
//hard disk image,you can use dd command to create a image
"disk": [
"/Users/xVM/ubuntu20/disk.img"
],
//shared folder, hostpath,guestpath paired value
//when start vm,easyvm will output the command to mount devices,
//you can add that mount command to the .profile file
"shared": [
["/Volumes/work/nvtscript","/opt/nvtscript"],
["/Volumes/work/NVTStudio","/opt/NVTStudio"]
],
"cpu": 4,
"memory": "4GB",
//linux kernel image
"kernel": "/Users/xVM/ubuntu20/vmlinuz",
//linux initrd image
"initrd": "/Users/xVM/ubuntu20/initrd",
//linux kernel command line
"commandline": "console=hvc0 root=/dev/vda"
}
2、use easyVM to start VM
use the easyVM.json file in the current directory
./easyVM
use special config file ,example ./debian.json
./easyVM ./debian.json
-
download the vmlinuz and initrd image:https://cloud-images.ubuntu.com/releases/focal/release/unpacked/ubuntu-20.04-server-cloudimg-amd64-vmlinuz-generic to ./ubuntu20/vmlinuz
https://cloud-images.ubuntu.com/releases/focal/release/unpacked/ubuntu-20.04-server-cloudimg-arm64-initrd-generic to ./ubuntu20/initrd
(M1 chip should choose arm64 version) -
download the cloud image : https://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-amd64.tar.gz and extract to ./ubuntu20/focal-server-cloudimg-amd64.img
-
dd if=/dev/zero of=./ubuntu20/disk.img bs=1 count=0 seek=30G to create a hard disk image
-
now edit config file
{ "name":"ubuntu20",
"cdrom": ["./ubuntu20/focal-server-cloudimg-amd64.img"],
"disk": [
"./ubuntu20/disk.img"
],
"shared": [
["/Volumes/work/nvtscript","/opt/nvtscript"],
["/Volumes/work/NVTStudio","/opt/NVTStudio"]
],
"cpu": 4,
"memory": "4GB",
"kernel": "./ubuntu20/vmlinuz",
"initrd": "./ubuntu20/initrd",
"commandline": "console=hvc0"
}
use this config file to start VM,you will enter the ubuntu initramfs,now you need copy the cdrom image to disk.img,and modify the root password
(initramfs) dd if=/dev/vda of=/dev/vdb bs=1024k &
(initramfs) mkdir /mnt
(initramfs) mount /dev/vdb /mnt
(initramfs) chroot /mnt

CTL+C exit 5. remove cdrom from confile and modify command line
{ "name":"ubuntu20",
"cdrom": [],
"disk": [
"./ubuntu20/disk.img"
],
"shared": [
["/Volumes/work/nvtscript","/opt/nvtscript"],

"memory": "4GB",
"kernel": "./ubuntu20/vmlinuz",
"initrd": "./ubuntu20/initrd",
"commandline": "console=hvc0 root=/dev/vda"
}
now start VM,you will enter the ubuntu
