| Doc Text: |
Previously, using the qemu-kvm system_reset utility when no space was left on on the host caused the qemu-kvm service to terminate with a segmentation fault. The underlying source code has been modified to fix this bug. As a result, the qemu-kvm process stays active, and guest systems can be reset without an error.
