Re: bhyve max virtual CPUs
Hi Allan, I asked about increasing it and was told that it can be done by editing a value in one of the .h files or something, but the reason it wasn't higher was that it didn't scale nicely, and they wanted to reword how it works. I would definitely be interested in this, as we run video transcoding (uses a LOT of cpu) on 24 or 32 core machines, and we'd like to pass more of the cores into the VM. You can bump it by modifying: sys/amd64/include/vmm.h:#define VM_MAXCPU 16 /* maximum virtual cpus */ ... and rebuilding world+kernel. Let us know how performance goes with larger values. It will probably be a while before this value can be dynamic, but that's the goal. later, Peter. ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

bhyve max virtual CPUs
Hi, Currently it seems bhyve has a max of 16 virtual CPUs, is that right? Or am I misunderstanding something? And if so, can we get that increased to 32 at least?
