Install KVM libvirt and setup access (the following commands are for Red Hat, for other distros it may be a little different)

• sudo yum install kvm virt-manager libvirt libvirt-python python-virtinst libvirt-bin sudo yum groupinstall "Virtualization Hypervisor" "Virtualization Client"

• To restart libvirtd, run one of the following: service libvirtd restart /etc/init.d/libvirt restart

• To grant a user access, add the user to the group named libvirt sudo usermod -G libvirt -a

• To test whether a user has access to libvirt, use the following python snippet. It should return a valid conn object.

  import libvirt conn = libvirt.open('qemu:///system')

From here on, you can start setting up and using the autograder...

The basic idea is to use domains for testing students' code.

• Define and start the testing domain(s)
• Take a clean-slate snapshot as soon as the domain is up and running
• For each students in the queue:
  • Uploaded and grade a student's code, and send results back to the autograder running on the node
  • Restore the domain to the clean-slate snapshot
