Fusion 11
Mojave 10.14.1
Windows 7 (Fusion hardware version setting 16 in Settings, Compatibility)
I've run Fusion for years.
11.0.0 was quick but recently the resume function starting taking forever (10-20 minutes).
I shutdown the VM and used Settings/General to clean the VM, which was already set to automatically clean. This didn't help.
But on restart I noticed an error that didn't appear during suspend or resume: something about not being able to connect to an .iso file in the DVD drive (it named the full iso file name).
About 15 days ago I installed a program in Windows 7 from an iso file mounted as a virtual DVD on the Mac side (the Windows connected to this [virtual] DVD drive).
About 5 days ago I moved that iso file that was still sitting on the Mac side to an external hard drive not involved with Fusion.
Fusion was obsessed with re-connecting the DVD drive with that particular iso file.
FIX
I shutdown Windows, then went into Fusion Settings, clicked the icon CD/DVD (SATA), then unchecked the "Connect CD/DVD drive" checkbox. Before then I also clicked off the iso file name on the pull-down list but forgot the exact order of clicks it took to get rid of the iso file listing. After I finished, the box was unchecked and the pull-down menu (only didn't have the iso file listed on it anymore).
Anyhow, I left "Connect CD/DVD drive" unchecked and now the VM resumes super fast like it used to.
Maybe this will help someone else.
