When installing the beta of System Center Virtual Machine Manager 2012 I ran into the problem where the installation needs at leased 2G of RAM. My VM only got a startup amount of RAM of 512MB because of the limit amount of available RAM in the Hyper-V host. Actually I gave the VM the dynamic amount of 512MB to 4GB.

Solution is easy! Shut down the VM, give it a fixed amount of RAM for installing SCVMM2012 Beta and afterwards change it back to the dynamic amount of memory you would like it to use!

Funny that it only needs to see 2Gb of RAM, it doesn’t actually uses it! Also when you address a dynamic range of 2-4Gb memory it will give you an warning message but it will continue installing

I also needed to fix the IIS problem. What I really do not understand that when you start the installer of SCVMM 2012 Beta you are asked if it is ok to install .Net 3.5.1 Framework. Why not do this for IIS also? Might be an option to at least give the option to install the correct version. You also need to install Windows® Automated Installation Kit (AIK) which can be found WAIK.
