The whole thing works:
% grep . /sys/devices/system/cpu/vulnerabilities/* /sys/devices/system/cpu/vulnerabilities/meltdown:Mitigation: PTI /sys/devices/system/cpu/vulnerabilities/spectre_v1:Vulnerable /sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full generic retpoline
I bet the virtualbox modules compiled by virtualbox-dkms will taint the support, but I bet sooner or later they will support retpoline as well. (Another reason to switch to KVM one day.)
Thank you. -- Martin
