I program a high performance C++ client-server based application by day and mourn the fact I don't program for OS X any more!

comment Xen vs KVM in performance
ahhhh, im with you now. yeah, I used to use libvirt and virsh but it was to cumbersome, then I moved away but now I'm back with virt-manager over forwarded X. Got tired of maintaining my own scripts and config files :)

comment Xen vs KVM in performance
@3dinfluence: I think you might misunderstand how USB and PCI support is implemented - libvirt doesn't do any of these things itself, it only provides a way of configuring the underlying capabilities of the VM hypervisor. In this case the capabilities are provided by a combination of the KVM kernel modules and the Qemu userspace code.

Interesting you note moving to KVM for USB support - I've just had to think about moving away due to the lack of USB 2.0 support! I'm guessing from your post that Xen isn't going to be much better.

Good question...I wanted to ask exactly the same thing myself (am in an identical scenario).

@Luca: actually since qemu 0.12 you can change the topology. I've upgraded my userspace kvm components but I think I need the new kernel mod for it to work....anyway, it can be done :)

Wow, I did't know this. Thanks for correctly putting your finger on the issue. @Luca: do you know if such support is planned? I'm I actually using the extra two cores or are they going to waste?
