RBVM Bugs are now tracked on Bugzilla


Old bugs

  1. Unassigned Minor Bug: VM names can be set to empty string. Cosmetic bug only.
  2. Fixed: r70 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) (removed use of PTYs)
  3. In progress (werdz) Major Bug: 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.
    1. Addressed a little in rev 70, still not quite there.
    2. This is happening at random again. Changed this from improvement to major bug, and added some debug info to figure out why this still isn't working 100% in r76.
    3. This seems to have stopped happening since power on detection rules were relaxed (/proc timestamp checking was removed). Keep an eye on it though.
  4. In progress (lil_cain) Moderate Bug: Session cache should be cleared when the system starts up, otherwise lock errors cause some peoples' sessions to asplode.
    1. I believe I have this fixed, just waiting for werdz to review before merging
  5. Unassigned Improvement: Logging and debug levels, etc, need to be cleaned up properly.
  6. Fixed: r66 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.
  7. Fixed: r65 Improvement: Add extra columns (MAC, IP, status) to homepage.
  8. Fixed: r72 Improvement: Add hardware options to front end (NIC controller, etc). Backend added in rev 70
  9. Fixed: r69 Improvement: Boot device selection
  10. Fixed: r73 Minor Bug: Live boot device selection didn't interact with KVM properly
  11. Fixed: r75 Improvement: Add ACPI control (-no-acpi KVM cmd line option) to KVM module and frontent.
  12. Invalid Moderate Bug: IO performance sucks since a kernel update last week. Some security patches for KVM were involved. Investigate.
    1. This turned out to be a misconfiguration on daniel. Not a bug in the RBVM source code.
  13. Unassigned Critical Bug: Somebody forgot to turn Daniel back on after the move. Fixitfixitfixit.
