Symptoms

PCA pre-checks fail while trying to upgrade to 2.3.4.

The "pca_upgrader -V ..." reported failures. The /var/log/pca_upgrader log shows the first error is:

This might be reported for more than one and various compute nodes.

Subsequent reruns fail with the same "Failed to complete SSH:" error, but subsequent "server .... does not exist" messages may be for different compute nodes. 

The OVM Manager and "pca-admin list compute-node" show the compute nodes are present and not in any error status.

Neither of the following resolve the issue:

• service ovmm stop; service ovmm start
• disabling password-less authentication on the OVM command-line interface
