----------------------------------------------
Summary: Switch remoteSSHClient in marvin to use fabric
Key: CLOUDSTACK-4677
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4677
Project: CloudStack
Issue Type: Improvement
Security Level: Public (Anyone can view this level - this is the default.)
Reporter: Prasanna Santhanam
marvin currently does all ssh connections using remoteSSHClient interface.
There are several other methods that basically end up calling remoteSSHClient.
Fabric on the other hand provides a more lucid and pythonic interface to deal
with ssh-connections. Underneath fabric uses paramiko and provides several
improvements
1. KeyPair support
2. Improved logging (current ssh logging is too verbose and hard to
troubleshoot with)
3. parallel execution (useful for getting simulataneous LB connections going)
In this work we need to deprecate marvin's remoteSSHClient from both the
library and the tests and provide fabric interfaces to deal with cloudstack
deployedVMs and hosts on the cloud infrasrtucture
