I'm having a ton of memory issues with VirtualBox (4.3.14) running Windows 7. These include:
- On startup, I get the following error: "Windows created a temporary paging file on your computer because of a a problem that occurred with your paging file configuration when you started your computer. The total paging file size for all disk drives may be somewhat larger than the size you specified."
- Excel (2013) runs out of memory a lot. Example: Try to save file (~5 MB max) and get "Disk is full" error.
- I can't upgrade or uninstall Skype because: "An error occurred while writing installation information to disk. Check to make sure enough disk space is available and click Retry or Cancel the Install."
I've fooled with the VM settings a little bit (experimenting with "nested paging"), but otherwise haven't done much.
