I am looking at [1] to get the feel for how do we model it in the XML. As you can see I am using ad-hoc <qemu:args> to create the sev-guest object. Currently, sev-guest object accepts the following properties:
dh-cert-file: <file containing the GO DH key> session-info-file: <file contain the GO session info> policy: <int32 GO policy>
I believe the new XML model will influence the property input type, Any recommendation on how do model this part ? thank you so much.
That looks ok to me - even if QEMU wants the data provided in files on disk, libvirt can just create the files on the fly from the data it has in the <sev> element in the XML file. Since they're only needed during startup, libvirt can then easily delete the files the moment QEMU has completed its startup.
/dev/fd/N filenames could be used for poor man's fd passing, I think. (/dev/fd is a symlink to the /proc/self/fd directory) proc(5) has documentation on this. Thanks, Laszlo
