New comment by pullmoll on void-packages repository https://github.com/void-linux/void-packages/pull/24725#issuecomment-688455264 Comment: Ok, now it builds but due to the "VBOX_WITH_VIRTIO =" without support for e.g. Redhat ethernet virtio drivers on my Windows guests. After switching the NICs to a supported type, after removing the old 6.4.10 extpack and installing the new 6.4.14 extpack I can run my VMs also on Linux 5.8.7.
