Hi,
i have Hyper-V host 2012 R2 on which only hyper-V role is installed and computer is in domain enviroment. I have installed windows 2012 virtual machine and installed hyper-V integration tools on that virtual machine. Till here no error messages, no warning nothing. After rebooting virtual machine mouse network doesn't work. So after a few tries i have installed legacy network card which guest VM detects correct drivers. After digging deeper i saw that guest VM doesn't properly detect drivers saying error code 52 and error code 39 ( or that drivers are not digitally signed or damaged). i have exported drivers from vmguest.iso from another host and tried to install but no luck. Both computers are up to date, everything else is working fine, no error messaged.
wrong drivers are:
MS GHyper-V video, MS Hyper-V Virtual keyboard,MS Hyper-V Network, MS hyper-V S3 Cap, MS Hyper-V generation counter.
Any ideas?
