Hi misc@, I've been experimenting with VMM and trying to load up a host with a number of servers.
I've observed that with 7.8 on 512MB servers, reorder_kernel will involve some swapping. It works fine if running a couple, but if starting plenty, it takes quite a while to finish as swapping to disk through VMM is pretty slow. If I disable swap, reorder_kernel fails, but the host disk doesn't get thrashed. With 768MB and no swap, things seem to behave pretty well. I suspect it'd be the same situation with 768MB and swap. Is it possible to remove kernel options not useful for VMs, such as say DRM and graphics drivers, and not have those as part of the linking process? I imagine that would lower reorder_kernel memory consumption quite a bit. To be fair, this isn't something most will run into. I've been testing with 32-46 small VMs. I have played with vm.conf's stagger setting, which I am sure I can make work with 512MB servers, but it would significantly slow down the time to get back online. I'd love to have 512MB servers not swapping on every boot. I will say, VMM is a joy to use and very straightforward. So far it seems quite reliable. Thank you! -Henrich
