RBVM Bugs

This page lists bugs with the redbrick VM system (at https://vmweb.redbrick.dcu.ie, documentation here).

1. Minor Bug: VM names can be set to empty string. Cosmetic bug only.
2. Major Bug: For some reason, on VM power on, the os.read() call on the monitor pseudoterminal blocks occasionally, causing the power on to fail (and the KVM process to stay running)
3. Moderate Feature: VM powered on detection needs work, it should check by MAC address and disk image name to try to detect when a VM power on failure has occurred.
4. Moderate Bug: Session cache should be cleared when the system starts up, otherwise lock errors cause some peoples' sessions to asplode.
5. Improvement: Logging and debug levels, etc, need to be cleaned up properly.
6. Moderate Bug: If new VMs are created as root, the mode and ownerships of the VM images under /var/lib/rbvm/images is completely wrong - VM will refuse to start as the rbvm user can't read/write the image.
