Thanks a lot for taking the time, Frank!
Ok then!
(1) My user should have read access to CDs (it's a reading device only) and
read/write access to the device file:
[EMAIL PROTECTED]:~$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 6 2007-01-22 07:27 /dev/cdrom -> cdrom0
[EMAIL PROTECTED]:~$ ls -l /dev/cdrom0
lrwxrwxrwx 1 root root 3 2007-01-22 07:27 /dev/cdrom0 -> hdc
$ ls -l /dev/hdc
rw-rw---- 1 root cdrom 22, 0 2007-01-22 07:27 /dev/hdc
$ ls -l /dev/dvd*
lrwxrwxrwx 1 root root 4 2007-01-22 07:27 /dev/dvd -> dvd0
lrwxrwxrwx 1 root root 3 2007-01-22 07:27 /dev/dvd0 -> hdc
$ groups
users video cdrom vboxusers
(2) The strace output contains no EPERM entries. Trying to run the SDL GUI I
get:
$ LD_LIBRARY_PATH=. strace -s 1024 -f -o LOG ./VBoxSDL -vm WinMCE
VirtualBox SDL GUI 1.3.3 built Jan 22 2007 07:56:28
Informational: VirtualBox object created (rc=00000000).
Error: failed to power up VM! No error text available (rc = 0x0 state = 1)
[EMAIL PROTECTED]:~/Apps/vbox/out/linux.x86/release/bin$ Informational:

object deleted.
Searching for "access" gives me this:
$ grep -ri access LOG

18413 access("/home/alex/Apps/vbox/out/linux.x86/release/bin/.autoreg",

18413 write(1, "Failed to start VM execution (VERR_ACCESS_DENIED)\n", 50) =
50
Well, the LOG file is pretty long, so I hesitate to post it inline. Not
sure, if it would help, but could I post it as an attachment? Is that
allowed for this group?
Thanks
Alex
