Windows Host Unresponsive when trying to start second VM with VMMR0.r0 ( VMMR0+1447c )

[Peggy]

I have 2 Virtual servers I need to spin up at the same time. They are Oracle Linux images for Peoplesoft applications. Sometimes I can get both running and other times, I get the first one running and the other guest starts to boot but then the host becomes unresponsive and I have to power reset it. I have dump files from the last occurrence. Using Windows Debugger with the mini dump file seems to points to VMMR0.r0. I will post what log files I can but it seems like it does not actually write a log for the server that crashes the host (random as to which one). *
