You appVMs may vary: in my work vm, where I use 2 IDEs (Android Studio and MonoDevelop) + android emulator + firefox + thunderbird, I capped at 10GB and it works ok. My workstation has 32GB ram. > - VCPUs - defaults to 2 but I can pick a maximum of 8. Which should I > choose (processor is Intel i7)? Don't overprovision vCPUs: the hypervisor will have to find *that many* cores free at the same time to run your VM, and that's why VMWare recommends 1vCPU for every VM on their ESX/ESXi infrastructure that you can upgrade to 2 if needed. I am against giving more than 2 vCPUs per VM in Qubes, and I recommend careful experiments when tweaking this value (increment by 1 and test with your actual workload, if there are performance gains or losses). > - Tickbox for include in memory balancing. What difference does this > make? Should I tick it for all VMs? You cannot have memory balancing enabled for VMs with devices attached; apart from that, there's no actual reason to allocate fixed amounts of RAM for you VMs. Say, you dedicated 10GB out of 16 to one important VM, but now you're just upgrading your templates with all the appVMs turned off, and you'd like the templates to benefit of all available memory without having to manually correct allocations. Or you just closed your personal Firefox instance to gain a little room for a big compilation in the work AppVM. TL;DR: I think the defaults provided in Qubes are reasonably ok, and while they may be changed if needed, changes should be tested carefully - knobs are inter-dependent, and giving "more" of any one may actually reduce performance overall, or for specific tasks. -- Alex -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
