Virtual Machine images were replaced on July 5, 2018. If you are using older VM images, you might consider transitioning to the newer VM. Otherwise, running new labs will require large downloads that may consume your VM resources.
- VMWare virtual machine windows sometimes become hard to use, depending on your platform. Try using: "View" / "Autosize" / select "Autofit Guest".
- If you have trouble installing a 64-bit guest on VirtualBox on Windows 10, refer to this link:
https://forums.virtualbox.org/viewtopic.php?f=1&t=62339 Or, run
bcdedit /set hypervisorlaunchtype offfrom an elevated command prompt.
- If a VMWare virtual machine becomes unable to reach your network, this can usually be resolved by rebooting your system, e.g., your Mac. Alternately, these commands often work from within a terminal on the Mac:
- sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --configure
- sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop
- sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli –start
- Get updates by running update-labtainer.sh (These include fixes to student and instructor environments.)
- If the "labtainer" (or start.py) commands do not do anything, your installation has been corrupted. You can recover from that as follows:
- Get updates by running labtainer/setup_scripts/update-designer.sh
- Periodically use the /labtainer/setup_scripts/cleanupDocker.sh to remove unused images. This will reclaim disk space consumed when doing many iterations of building the same lab.
- As a last resort, use the labtainer/setup_scripts/destroy-docker.sh to fully erase all local Docker images. Then use pull-all.sh to pull in all baseline images (several GB download).
