Re: [PATCH 0/5] i386: simplify Hyper-V enlightenments enablement

[Claudio Fontana <cfontana@suse.de>]

Hi Vitaly, I just wanted to raise awareness of

https://lists.gnu.org/archive/html/qemu-devel/2020-11/msg04597.html

because if that series work is completed, you would have already the right hook to put your code in, when it comes to your hyperv-specific code for the realizefn.

Ciao ciao,

Claudio
