I have not used TumbleWeed, but the VM guest "tools" compiled into the kernel is common thing with Linux.
The idea is that you need get the Parallel Tools script to run on the guest.
This is similar when using VirtualBox with Linux as well. The installer/script will compile the "VM tools" into the guest kernel.
You are running into a snag due to the development tools and/or the kernel source files are not installed yet on the guest. Basically the guest kernel needs to compile some VirtualBox Tools stuff.
You need a command similar to
Code:
zypper install gcc kernel-devel
good luck
