Our host (ESXi 4.1) has a dedicated guest with all the memory allocated to it. The guest is running SQL, and we often experience performance problems. Veeam One reports ballooning above 10%, and that is odd. If ballooning happens by borrowing memory from another VM, how is it possible in this scenario of only one VM?
The next question is what is the best way to fix this ballooning issue? I'll note that I found the guest has 32 GB assigned to it which is the amount on the host. I plan to reduce the allocated memory for the guest to 31 GB in order to make memory available for the host OS.
