Hi all,
looking at the documentation of void IMachine::lockMachine (in
ISession session, in LockType lockType) here
https://www.virtualbox.org/sdkref/interface_i_machine.html#af28da645b00a821547d9cb8e92f8b7b0
it seems that there are 2 strategies
lockType
if set to Write, then attempt to acquire an exclusive write lock or fail.
If set to Shared, then either acquire an exclusive write lock or
establish a link to an existing session.
In my test I lockSession with Write type and then I was trying to lock
with Shared type the same machine, but I get an exception
java.lang.RuntimeException: error locking
jclouds-image-0x0-machine-utils-live-test with Shared lock: VirtualBox
error: The given session is busy (0x80BB0007)
