Hi Jonathan, What is being reported is that a guest was running Ubuntu v12 with kernel 3.9.x-generic on a host that was running Ubuntu v14 with kernel 3.13.x-generic and the engineer had problems with reliably mounting/unmounting volumes and that problem was corrected by upgrading the gusts to kernel 3.13.x-generic.
Have you run into this or has anyone else run into this before? I'm CC'ing a colleague who can offer additional insight. //adam *Adam Lawson* AQORN, Inc. 427 North Tatnall Street Ste. 58461 Wilmington, Delaware 19801-2230 Toll-free: (844) 4-AQORN-NOW ext. 101 International: +1 302-387-4660 Direct: +1 916-246-2072 On Tue, Sep 6, 2016 at 4:22 AM, Jonathan D.
