First, the hardware is fine and no messages are logged by physical machine, the errors are all coming within the VM. I am running latest version of parallels on the new macbook pro with the PCIe-based SSD. This is a FAST SSD, and I can do well over 1.5 Gbytes/sec (that is NOT a typo) so that may be a factor.
I am using ZFS for these logical drives and all virtual host O/S settings are default.
The VM itself reports these messages when I have such problems.
