Modifiers:
Use the test directories that have been modified when running and
comparing tests:
modified
apply operation to modified tests (default is all tests)
When comparing results, specify the baseline directory to compare
against (default is Makefile.inc.local:KVM_BASELINE):
baseline
compare test results against baseline
baseline-passed
compare test results against baseline tests that passed
baseline-failed
compare test results against baseline tests that failed
--baseline <dir>
specify baseline directory to compare against
--baseline-passed <dir>
specify baseline directory to compare against
--baseline-failed
specify baseline directory to compare against

Set up the test environment, run the testsuite:
install[-PLATFORM]
if needed, create the build domains
install libreswan on the build domains
clone the build domains to create the test domains
control with Makefile.inc.local:KVM_{FEDORA,FREEBSD,NETBSD,OPENBSD}=true
check [ <test-directory> ... ]
run the testsuite
Examine the test results:
diffs [ <test-directory> ... ]
show differences (for the specified tests)
exit non-zero when differences are found
results [ <test-directory> ... ]
list test results (for the specified tests)
exit non-zero when failures are found
failed [ <test-directory> ... ]
list failed test results (for the specified tests)
(XX: broken: exit non-zero when failures are found)
Re-run, or run a-new the testsuite:
recheck [ <test-directory> ... ]
re-run the testsuite
uninstall
deletes test domains
deletes build domains
leaves test results and keys alone
clean
deletes test domains
deletes build domains
deletes test results
deletes test keys
check-clean
delete the test results (leave the build trees and domains alone)
keys
deletes test keys, and then rebuilds them
Update the expected test results (and GIT repository):
patch [ <test-directory> ... ]
apply test differences (to the specified test directories)
add [ <test-directory> ... ]
<<git add>> (the specified test directories)
Manipulate the kvmrunner process:
status
report the status of the running test
kill
kill the running testsuite
nohup
run in the background
Step wize create/delete the domains (just use ./kvm install):
base[-PLATFORM]
create a domain containing the base OS
creates: ${basehosts}
upgrade[-PLATFORM]
create the upgrade domain from the base domain
installs missing packages
updates existing packages
creates: ${upgradehosts}
transmogrify[-PLATFORM]
create the build domain from the upgrade domain
transmogrifies the domain ready for building and testing
creates: ${kvm_platform}
build[-PLATFORM]
build/install libreswan on the build domains
uses: ${kvm_platform}
install[-PLATFORM]
build/install libreswan
clones build domains to create the test domains
Stepwize delete the domains (just use ./kvm purge):
shutdown[-PLATFORM]
shutdown all domains
uninstall[-PLATFORM]
delete test-domains, build domain
leaves base domains and upgrade domains alone
downgrade[-PLATFORM]
also deletes upgrade domains
also deletes test keys
also deletes test results
purge[-PLATFORM]
also deletes base domains
demolish[-PLATFORM]
also deletes shared gateway
Libvirt breakage:
restart
restart libvirt to workaround catatonic daemon performance
To log into a domain:
sh <host> [ <command> ]
start a shell on <host> which can be a:
test domain: ${testhosts}
build domain: ${kvm_platform}
base domain: ${basehosts}
upgrade domain: ${upgradehosts}
Configuration:
config
show the configuration
Namespaces - broken:
nsinstall
install namespaces
nsreinstall
re-install namespaces
nsrun [ <test-directory> ... ]
run testsuite using namespaces on the fedora domain
