Solution to: Getting Kernel Panic After Update of Virtual Machine

If you recently updated your Centos VM you may started getting the error below:

Kernel panic -- not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

unknown-block may change depending on your configuration, but symptoms stay same: Kernel panic after the update, and this error message.

Solution is:

yum remove kernel
yum update

That fixed my problem. Hopefully it fixes yours.
