I am new to Hyper-V. I have tried to launch some previous VM's that were created in Win7 Virtual PC and the first screen that pops up is [Windows Security] that says my credentials did not work (not even Administrator). However I did manage to get one of the usernames, who is an admin, to start the VM. The next popup reads 'This user account cannot access the virtual machine's video.....'. I have searched all over and can't seem to find anything with a solution. In reading some articles concerning RemoteFX 3D Video adapter, I have tried, in Settings' but cannot remove this video adapter-the remove button is greyed out.
I have also tried installing a new VM install of Windows7 from the DVD drive and again I get the same 'cannot access video' error.
The PC is an AMD FX6100 and yes, the VT has been activated in the Bios.
Any suggestions? Much appreciated.
I can suggest you a simple story about Hyper-V,
You just make one more VM named as Win-7. and install os from CD / ISo Image on this vm.
Now try to acces it. It will work.
Rest about you VMs which was running on Virtual PC; these VMs can also work. simply you need to make a new vm in Hyper-v where at the time of hard disk creation page; you will save use an exisitng there you can browse the .vhd of the vm (Which was runnig on Virual PC).
