Host: Ubuntu 13.10
Guest: Windows 8.1 Enterprise Preview Memory 8 GB 1 CPU
The Windows 81. guest boots extremely slowly. The circular boot icon stops and starts many times. Boot takes well over 5 minutes. To compare a nested Windows 2012 Server 2 Preview boots with no circular days whatever bootsd maybe 5 times fast than the containing Window s8.1 container.
I can disable all start up programs on the Window 8.1 guest using CCleaner Start up Tool). This makes no difference. Once the guest does boot performance is OK.
VMware or OS? I can't lower the memory assign because of the Hyper-V machine. I could define more than one CPU however (I have a hex core AMD).
