assigning PCI addresses with bus > 0x09
Hi,
My goal is to assign PCI addresses to a number of devices (network
interfaces, disks and PCI devices in PCI-passthrough) without delegating to
libvirt the generation of those values. This should give me more control
and for sure more predictability over the hardware configuration of a
virtual machine and consequently the name of the interfaces in it. I'm
using libvirt 4.3.0 to create

"failed to setup INTx fd: Operation not permitted" error when using PCI passthrough
...every i350 interface has its own IOMMU group in
/sys/kernel/iommu_groups/.
The kernel I'm using in the host machine is 4.9.189 and my libvirt version
is 4.3.0.
Any thoughts on this?
Is there something I should enable in the BIOS or in the kernel to make
this work?
Thanks!

"scripts are not supported on interfaces of type vhostuser" error
Hi,
I'm having trouble starting a VM with vhostuser interfaces.
I have a simple configuration where a VM running Debian has 1 vhostuser
interface plugged into an OVS switch where a DPDK interface is already
plugged in.
$ ovs-vsctl show:
Bridge "switch1"
Port "switch1"
Interface "switch1"
type: internal
Port "1.switch1"

Re: "scripts are not supported on interfaces of type vhostuser" error
Spot on! The script qemu-ifup was indeed the cause of the problem. It's a
dummy script that only does "exit 0" and it was apparently needed in the
past with old versions of libvirt. I see examples on the net where it is
used to configure interfaces with shell commands. I don't need it.
I see that everything works fine without the <script

performance overhead with backing chains?
Hi,
I was wondering if there are any studies on the performance overhead of a
QEMU/KVM virtual machine when the backing chain of its disk(s) is of size
n, with n > 1. In particular, it would be useful to know until what size we
can expect little or no impact on a Linux virtual machine, for instance.
Thanks!

Laine,
Do you have by any chance a link to a page explaining this in more details?
Thanks again! :)
