McKenney Date: Wed Jun 23 17:07:06 2021 -0700 torture: Move parse-console.sh call to PATH-aware scripts The last line of kvm-test-1-run-qemu.sh invokes parse-console.sh, but kvm-test-1-run-qemu.sh is unaware of the PATH containing this script and does not have the job title handy. This commit therefore moves the invocation of parse-console.sh to kvm-test-1-run.sh, which has PATH and title at hand. This commit does not add an invocation of parse-console.sh to kvm-test-1-run-batch.sh because this latter script is run in the background, and the information will be gathered at the end of the full run.
