Debian Jessie kvm vm – intel_rapl not found error on boot

August 9, 2015 Leave a comment

Just blacklist this module. Add a .conf file to /etc/modprobe.d

intel.conf
blacklist intel_rapl

or any other .conf blacklist you already have as any .conf file is searched.

reboot

systemd display-manager.service error kvm vm, Debian Jessie os

If you are receiving this error in dmesg upon boot:

Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory.

Execute these commands via cli to fix.

1) systemctl get default (look at result)
2) If the result is graphical display, then continue with 3
3) systemctl set-default multi-user.targetsys
4) systemctl get default (recheck result) should be multi-user.target

reboot your vm and you should no longer see the error in dmesg.
