COMPUTE_API_VERSION = "2.17"
# It's a resource-consuming task to implement full-flow (up to getting
# and reading a dump file) functional test for trigger-crash-dump.
# We need to upload Ubuntu image for booting an instance based on it,
# and to install kdump with its further configuring on this instance.
# Here, the "light" version of functional test is proposed.
# It's based on knowledge that trigger-crash-dump uses a NMI injection,
# and when the 'trigger-crash-dump' operation is executed,
# instance's kernel receives the NMI signal, and an appropriate
# message will appear in the instance's log.
# The server status must be ACTIVE, PAUSED, RESCUED, RESIZED or ERROR.
# If not, the conflictingRequest(409) code is returned
