Trying to update the kernel-devel/kernel-headers to match the 4.4.x version, I ended up with a conflict and I was unable to update the kernel-headers with the 4.4.x version.

So we have a pre-requisite of our pre-requisite, which consists of ' preparing guest for building external kernel modules'Īnd our HDP 2.6.4 doesn't seem ready: the running kernel (4.4.x id I'm right) and the kernel-devel and kernel-headers versions do not match), which is a condition that is checked during the installation process.

In Virtualbox documentation Chapter 4 Guest Additions, it is said Not really ! The devil is inside the details. Then logout and re-login, it will be OK to open and write the share folder in the guest OS.The instructions given in the article avoid to mention a setup pre-requisite which is 'Installing VirtualBox Guest Additions' on the guest machine, that is to say installing it on our CentOS based HDP Sandbox VM. $ sudo usermod -a -G vboxsf MY_USER_NAMEĭouble check the groups of current user: $ id MY_UESR_NAME The solution is quite simple: add current non-root user to the vboxsf user group. But my current non-root user is not a member of vboxsf user group. Obviously the owner of the share folder is root and the group it belongs to is vboxsf. So I tried to look at its permission in terminal: $ cd /media/ The share folder was mounted at /media/sf_share in my Ubuntu guest. I was trying to open the share folder in Ubuntu guest but a 'Permission Denied' error raised. I created an Ubuntu guest OS in VirtualBox and gave it a share folder from host. Fix 'Permission Denied' issue when trying to access VirtualBox share folder in guest OS.
