mount: permission denied: loop devices mounted as scsi devices #677
Description
Description of problem
$ docker run --rm -ti --runtime kata-runtime --cap-add=SYS_ADMIN --device /dev/loop0p1 debian ls -la /dev/loop0p1
brw-rw---- 1 root disk 8, 0 Aug 30 17:54 /dev/loop0p1
according with https://www.kernel.org/doc/Documentation/admin-guide/devices.txt major 8 is for SCSI devices not loop devices, since now we are honouring devices cgroup in the VM, the device can't be mounted as it's not in the dice cgroup.
$ cat /sys/fs/cgroup/devices/devices.list
c 1:5 rwm
c 1:3 rwm
c 1:9 rwm
c 1:8 rwm
c 5:0 rwm
c 5:1 rwm
b 7:0 rwm
c *:* m
b *:* m
c 1:7 rwm
c 136:* rwm
c 5:2 rwm
c 10:200 rwm
a workaround to have mount working is to add 8:0 to the list of devices
