Ben: explicitely CCing you due to the question below. Thiago Maciera, the developer in charge of QHash, also works at Intel and made some points which you might find interesting.
From https://bugreports.qt.io/browse/QTBUG-69555 If the machine is question is virtual: make sure the host exports a virtual HWRNG for the guest to use. VMs will not collect enough entropy fast enough otherwise. You should consider using an entropy collector to reseed at boot. See haveged. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=898021 talks about a problem on IVB, but IVB has a hardware RNG. Is this really a cold boot? https://wiki.qemu.org/index.php/Features/VirtIORNG and https://wiki.qemu.org/Features/Real_rng_device Regards, Lisandro. -- Quizá, para muchos, ahora que lo pienso, Wikipedia tiene ciertamente un defecto imperdonable.
