tempest.scenario.test_snapshot_pattern.TestSnapshotPattern fails sporadically

[Ryan Hsu]

Two tests are failing from SSH timeouts on the check-tempest-devstack-vm-neutron job:

tempest.scenario.test_snapshot_pattern.TestSnapshotPattern
tempest.scenario.test_volume_boot_pattern.TestVolumeBootPattern

Exception message:

Sean, bug 1253896 is duplicate for SSH timeouts part, is there bug for "Timed out waiting for thing..." or is that too generic error?

[Alan Pevec (apevec)]

Answering to myself, "waiting for thing" is bug 1254890
