It just says that the process "init", with pid 1 crashed on cpu 0 and
gives the kernel version.

This is missing any kind of root=/extra=/cmdline= or bootloader=
statement, which would result in a root= on the kernel command line. So
the kernel has no way of knowing which partition contains a root
filesystem. Please check the wiki for numerous examples of how to
install a guest (even Centos specific ones) which have examples of
configuration files.
