## Virtual Machine
Tested with:
* Ubuntu image in VirtualBox and linux virt-manager / [cockpit-machines ](https://github.com/cockpit-project/cockpit-machines )
* Debian image in VirtualBox https://github.com/rootzoll/raspiblitz/issues/2756#issuecomment -983532237
* TrueNAS (FreeBSD bhyve) with an Ubuntu VM: https://github.com/rootzoll/raspiblitz/issues/2104#issuecomment -917444238
2021-12-26 22:22:33 +00:00
To just experiment can load a virtualbox image from: https://www.osboxes.org/ubuntu (does not need installation)
Password: `osboxes.org`
2021-12-11 13:03:45 +00:00
Can carry on straight to building the OS:
```
# download the build script
wget https://raw.githubusercontent.com/rootzoll/raspiblitz/dev/build_sdcard.sh
2022-01-25 13:28:57 +00:00
2021-12-11 13:03:45 +00:00
# run
2022-01-25 13:28:57 +00:00
sudo bash build_sdcard.sh -f true -b dev -d headless -t false -w off
# Options:
# -h, --help this help info
# -i, --interaction [0|1] interaction before proceeding with exection (default: 1)
# -f, --fatpack [0|1] fatpack mode (default: 1)
# -u, --github-user [rootzoll|other] github user to be checked from the repo (default: rootzoll)
# -b, --branch [v1.7|v1.8] branch to be built on (default: v1.7)
# -d, --display [lcd|hdmi|headless] display class (default: lcd)
# -t, --tweak-boot-drive [0|1] tweak boot drives (default: 1)
# -w, --wifi-region [off|US|GB|other] wifi iso code (default: US) or 'off'
2021-12-11 13:03:45 +00:00
```
2021-12-26 22:22:33 +00:00
Switch off when ready
2021-12-11 13:03:45 +00:00
and attach an other disk (can be even small if you prune or [stop bitcoind ](https://github.com/rootzoll/raspiblitz/issues/1500#issuecomment-982779830 ) ).
The second virtual disk will be used as the BLOCKCHAIN drive.
This makes that data portable and independent from the OS similar to the combination of the SDcard and separate SSD.
