trying to use physical disk in virtualbox but having errors due to permissions?

SO fwiw, i have to

sudo usermod -a -G disk $USER

and then reboot to use the

Code: Select all

VBoxManage internalcommands createrawvmdk --filename /path/to/filename.vmdk --rawdisk /dev/devid (sda or nvme0n1 or whatevs)

also the above command is deprecated anyway and the new one looks something like this:

Code: Select all

VBoxManage createmedium disk --filename=/path/to/filename.vmdk --variant=RawDisk --format=VMDK --property RawDrive=/dev/devid (sda or nvme0n1 or whatevs)

And my distro devs tell me that having a user in the disk group is a huge security risk and they advise not to do that so after creating the drive with the above commands and getting virtualbox to run the way i like i tried then removing my user from the disk group after setting it up. of course for groups you have to reboot after adding or removing a user from a group for it to take effect. In any case, my vbox will not work without my user being in disk group

Code: Select all

Could not open the medium
VD: error VERR_ACCESS_DENIED opening image file
(VERR_ACCESS_DENIED). Result Code: NS_ERROR_FAILURE (0X80004005) Component: MediumWrap Interface: IMedium

i also tried to chmod 777 the vmdk file and chown -R my directory and all it's content so far only adding my user to disk group works. is there another option to solve this probelm as i don't wish for the security risk of user in disk group. thanks.
