@slavkap the tests fail because the self doesn't have a snapshot that was supposed to be created in the class setup method. Is this a timing issue?

Hi all,
I believe that the test failure is not related to the changes in the PR. It fails while trying to list the mount path with the error:

AssertionError: False is not true : After umount directory should be empty but contains: ['sudo: unable to resolve host VM-5cc1cc35-742a-46bc-ae8c-6785a06829bf: Temporary failure in name resolution']
