I have a windows 2008 (virtual) machine, which I want to add a pagefile to. However, any time I try to set the page file size, after a reboot it jumps back down to 0. Why is this?

  • set the pagefile to system managed (unless you've given the VM massive amounts of ram) – Jim B Jan 12 '12 at 2:43
  • It doesn't work either, it always gets reset to 0 after a reboot. – user28622 Jan 12 '12 at 8:57
  • I am having the same issue on Server 2012 – Jack B Nimble Jul 23 '14 at 15:31

Click the "set" button after you set the size but before you click "Ok"

  • Yes, I have done that. – user28622 Jan 12 '12 at 8:57

If your server is a virtual machine, everything is a file already anyway, so there is no point in adding a pagefile. There is no physical memory to offload from, so it doesn't seem necessary to have a pagefile. Not sure what virtualization platform you are using, but perhaps Windows 2008 is detecting that it is a virtual install and basically disabling the page file.

  • The VM still uses physical memory, and will need swap space if it runs out, just like a physical computer. – Bigbio2002 Jan 13 '12 at 19:03
