Hi Malcom,

now we've installed the VM again from scratch (SLE-12-SP2-Server-DVD-x86_64-GM-DVD1) and have included the extension SUSE Manager 3 while the installation.
After running "yast susemanager_setup" following errors occuring (it looks similar like before):

- /var/log/susemanager_setup.log
/var/spacewalk already exists. Leaving it untouched.
Filesystem type for /var/cache is ext4 - ok.
