Hi there, This is a very interesting discussion in which I was reminded on the different cache modes.
I have a supplementary question dough. Sometimes if I change the cache mode of a guest system disk, the guest won't work properly (it hangs, crashes,...). Never yet with a nix system but It happens with Windows guests. Does anyone has experience with changing the cache mode on disks in Windows guest?
