I had Ubuntu 17.04 running in VMware when suddenly the whole macOS system slowed down and became nearly unuseable. I was running sudo apt-get upgrade inside a terminal in Ubuntu when I noticed the command didn’t seem to get executed since the terminal became stuck. Shortly thereafter macOS threw out a “disk space almost full” notification and as I checked the .vmware file inside my documents folder it had grewn from 15GB up to 2 TB taking up all my disk space. I killed every VMware process, deleted the .vmware file and rebooted my Mac. Now everything’s working again but I figure this shouldn’t happen normally.
Are any of the VM's running on snapshots? If there are snapshots, they may need to be consolidated, see Consolidating snapshots in VMware Fusion (1020000) | VMware KB
Otherwise, the logs may point to what caused the file to grow so quickly Collecting diagnostic information for VMware Fusion (1003894) | VMware KB .
I have a similar problem. I installed ubuntu on vmware + bitcored (to download the blockchain). While downloading the blockchain, vmware keeps using more and more diskspace EXTREMELY fast. Ubuntu itself shows ~13 gb usage of the filesystem while the vmware folder grows 30gb+, 300+gb, and so on. After the vmware disk space limit is reached, vmware crashed and I can not start the vmaschine anymore. Tips?

Nevermind, switched to VirtualBox!
