You are running out-of-free space in "cowspace" (tmpfs set to 75% of RAM).

Before all buffer I/O errors and filesystem errors you will see this: 
"device-mapper: snapshots: Invalidating snapshot: Error reading/writing."

Solutions:
* Increse memory in your VM.
* Attach a virtual storage, specify cowspace_size=1G, setup a swapspace 
on virtual storage
* Specify cowspace_size=1G, setup a swap space on zram block dev (staging)
   modprobe zram
   echo $((2**30)) > /sys/block/zram0/disksize
   mkswap /dev/zram0
   swapon /dev/zram0
