I would like to access the dmi values /sys/class/dmi/id/* of the hardware host inside the VE's.
E.g.
/sys/class/dmi/id/product_serial
/sys/class/dmi/id/product_uuid
I can achieve it using dmidecode(1) after applying
DEVNODES="mem:r "
CAPABILITY="SYS_RAWIO:on "
but I prefer the simple /sys/class interface because of security issues and because dmidecode can be spoofed.
I have looked at the kernel sources and thought it would an easy task but found the code too generic for me.
