I don't know what to do and I am ready to throw in the towel with Hyper-V and Windows 2012.
I have server R910 with 512 GB of RAM, a raid 10 disk array,etc. There is no machine more powerful build by the big iron companies. it has 64 cores,etc.
I created 200 identical virtual machines with one master and 200 differencing disks. The master is 20 GB long and it resides on a Ram Disk, so reading is the fastest. Each VM needs 1 GB of RAM only. The machines are all of them Windows 7. If I select them all in the Hyper-V manager and right-click -> Start, only about 1/4 start. The rest stay like frozen in several stages, but they never finish booting. I guess it is the creation of the swap file, which is 16 GB, and I cannot disable it because no matter what I do, Windows will create a minimal (16GB) swap file anyway. I cannot even redirect this file an external SSD or some similar trick,because Hyper-V does not allow that, like its competitors. As a result of this nightmare, I need to start each virtual machine 90 seconds apart, and for 200 units I need (200 x90)/60= 5 hours in order to fully boot my server. This is a joke.
Does anybody has any idea how to solve this riddle?
