[Users] Access Cdrom, reboot and other questions

[Kirill Korotaev]

Romeo,

1. please always report the exact messages you face.
2. check that iso9660 is available both in VE and in the host
with the command:
# cat /proc/filesystems
most likely you didn't load the module isofs:
# modprobe isofs

Thanks,
Kirill
