Thanks for the tips. My host has 1.25GB RAM, so I assigned 384MB to the guest. Maybe I could assign a bit more? I turned the guest video memory back down to 8MB.
I don't seem to have the option of using VT-x/AMD-V, it's greyed out, maybe my host processor doesn't support it (Intel Xeon 2.66GHz). I've already installed the guest additions, and USB support in the guest was already disabled. I haven't recompiled the guest kernel though. Will that make a big difference? I also uninstalled/closed as many programs in the windows host as possible. All this seems to have made a small difference, the vm feels snappier, applications and popup menus etc. are still a little slow to open, especially during screen capture, but slightly quicker than before. Maybe this is the best I can hope for? On Fri, Sep 19, 2008 at 7:22 AM, Frank Mehnert <[EMAIL PROTECTED]>wrote: > Some advises: > * More host memory is better. You should have _at least_ 512MB.
