Re: [Qemu-devel] unable to set SATA serial with a spaces

[Alan Latteri]

Yes, left pad.  This is a strace of the authorization program via VirtualBox

data[96]=["\0\200\0\24            ABCD1234\0\0\0\0\0\0\0\0"…]

then the same thing using the serial setting no spaces in QEMU.

data[96]=["\0\200\0\024ABCD1234            \0\0\0\0\0\0\0\0"…]

The spaces matter here.

I tried setting the spaces manually running QEMU from the command line, but that doesn’t work.

tried with quotes around the serial value and also using escpare characters.

No go.

Thanks,

Alan

Are you sure you need to input the spaces? the standard inquiry reply
that outputs the serial uses spaces as padding, so even if you use
serial "ABCD1234" the inquiry command is going to tell you
"            ABCD1234".

Are you sure it pads on the left?  padstr() doesn't look like left...
