Re: [Qemu-devel] [PATCH v5 0/4] Extend TPM support with a QEMU-external

Hi Quan,

I'm currently testing and reviewing. I also have some colleagues doing the same 
thing.

So far: I haven't had any issues with it - this seems to work quite nicely.

I will keep testing but I don't really expect any functional hiccups.

Best Regards,
Hagen
