After upgrade to vSphere plugin v. 2.23, no "Slave virtual computer running under vSphere Cloud" option in "New node" menu.
Only "Permanent Agent" and "Copy Existing Node" remains.
Old nodes, created via "Slave virtual computer running under vSphere Cloud" are still present and work.
But cannot create new ones, and if create new node as a copy through "Copy Existing Node", actual agent fails to connect via JNLP connection.
Downgrading vSphere plugin to v. 2.21 resolves this problem.
