Hi I have a Windows 7 x64 host and a Windows 7 x64 guest. Occasionally on the host I will switch over to the active windowed guest and there will be just violent disk activity and the guest freezes for a minute or more during that time. Using Windows' Resource Monitor on the host I was able to determine the only file being accessed and related to the rapid IO is a vmem file for the guest and it's being accessed by vmware-vmx.exe. The guest is not in sleep mode, I can see the windows in the guest and they just freeze with an occasional jittery update.
I fit all the RAM guests need into the host RAM so there's no paging there and also paging is disabled on the host.
Edit > Preferences > Memory > Fit all virtual machine memory into reserved host RAM
Despite doing that I just can't seem to stop the occasional freezes from happening. So far I've only noticed it with just the one guest but that may be because that's the one I'm using a lot recently.
So why is there all the I/O to the vmem file when the guest hasn't been interacted with for a while? Has anyone else noticed something similar or do you have any advice for me? It's becoming very annoying.
Thanks
