Windows Server 2016 virtual machines in the EduCloud Server environment may unexpectedly crash when increasing the number of CPUs while the virtual machine is powered on if it has been configured with less than 4GB of memory.
This is a known issue and has been identified by both VMware and Microsoft. There is no ETA for a resolution from the vendors.
To workaround the issue either:
– Power off the VM prior to increasing the number of CPUs, or
– Increase the amount of memory on the VM to 4GB prior to increasing the number of CPUs
