Howdy,

After the recent update to build 9926, I've faced issues running this build of Windows 10 Technical Preview in a virtual machine on my Windows 8.1 setup.

I can't connect to this Windows 10 machine from Hyper-V manager. The miniature screen of the VM display in Hyper-V Manager works fine showing some picture of the VM screen, however when I doubleclick the thumbnail, the opened connection screen stays black for forever continuously showing Connecting to <MachineName>...

Hi,

Is this problem occures as soon as Windows 10 Technical Preview installed?

According to your description, you were suffering a boot problem with this system. How much RAM you allocate to this system?

Hi Roger,

Yes, this happens so only with VM with Windows 10 TP and with 9926 build only.

I allocate minimum of 2 Gbyte of RAM with staring amount of 2 Gbyte.
