Clean instalation of Centos 6.6 with KVM from repo. first problem I've stumbled upon is that I din't manage to pass in some PCI devices. They share IRQ, even if I add them both, it fails on the first one in list (qemu complains I'm trying to pass something that shares IRQ). Is there any way around that? I could pass those devices in xen (hvm guest, therefore qemu too), they worked (even separately) second thing I'd like to setup is ps/2 passthrough (laptop keyboard and touchpad) - though I've found nothing on that. Is it even possible? what I'm trying to achieve is that I'll have minimal hypervisor and I'll pass all periphetals to the work guest, so I can have some applications as services on another VMs (in somehow safer environment in case some app is unsafe and the machine (VM) get's ever compromised) and I don't have one super-polluted workstation, but work one, where I have the I/O and bunch of headless ones I run optionally as I need them :) Thanks in advance, Gh.
