When you pass a device in the pci chain (after virsh
nodedev-dettach'ing it from host) to the guest, how much is passed

I would really appreciate some pointers on what I am doing wrong here.
I have a need to run multiple virtual guests which have each their own GPU and
some USB controllers passed-through. I am able to run one of the guests like
this (assuming vfio stuff has happened elsewhere), but I would prefer t

guest started with the 2 cards successfully inside, even mythtv works

i hope to find a way to somehow rearrange the irqs as i sometimes need

Hi everybody!
On a Centos 5.8 with libvirt qemu-0.10.5-1.el5.2, libvirt-0.8.2-22.el5 and
2.6.18-308.11.1.el5 I have a Windows machine that used to have pci-passthrough
for a device enabled and working.
After an update (kernel, libvirt afaik) and a reboot, pci-passthrough stopped

I'm trying to passthrough legacy PCI ISDN controller to a KVM based
virtual machine:
This only worked once. (The device disappeared from the lspci autoput

I've installed libvirt version: 0.9.4, package: 23.el6_2.8 from yum.
