After this, Ubuntu 14.04.4 x64 LTS doesn't boot correctly and hangs on this screen:
This happens on all VMs I'm trying. I can reproduce it by creating / reverting snapshots.

At Ubuntu Forums there's at least one thread showing that my issue is caused by the latest Ubuntu Kernel Update (linux-image-extra-3.19.0-51-generic):

Update:
@alexmurray filed a bug (which has been already confirmed) at https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1550090
Please vote over there if you're affected (please don't create "me too" answers here).
Update:
Fixed by
3.19.0-51.58~14.04.1I had the same issue and reverted back to the older kernel.
Hold Shift on boot up and select advanced options, then select an older kernel (Pay attention to what the latest kernel is). This will allow you to go into the Ubuntu desktop.
From there open up synaptic package manager. Locate
linux-image-3.19.0-51-generic(or the latest kernel you have installed).Right-click and select "Mark for Removal".
Apply and restart.
I haven't kept a record of the boot text information, but had similar problems (Windows 7 64-bit host VMware Workstation 12 Player), initially with the 15.10 Wily Werewolf VM I had been using for a while. After installing the latest updates a couple of days ago my VM wouldn't boot and got stuck on a black screen. I tried to work around the problem by creating a new 14.04.3 LTS VM from the .iso I had used before. This guest VM worked fine until I updated it and then it wouldn't boot either. So I tried a new install of 15.10 guest VM again and sure enough it seems to be something in the latest updates that is the cause (as the 2 VMs I tried have different kernels - I need a later kernel for USB 3.0 capability).
