xl create PV guest with qcow/qcow2 disk images fail
Hi, List,
I''m trying xl create a pv guest with qcow/qcow2 image, it always fails at libxl_device_disk_local_attach.

Proof of concept for GPU forwarding for Linux guest on Linux host.
Hi,
This is a proof of concept of GPU forwarding for Linux guest on Linux host.
I'd like to get comments and suggestions from community before I put more
time on it. To summarize what it is:
1. It's a solution to bring GPU acceleration for Linux vm guest on Linux host.
It could works with different GPU although the current proof of concept only
works with Intel GPU.
2. The basic idea

[RFC 0/3] virtio-iommu: a paravirtualized IOMMU
This is the initial proposal for a paravirtualized IOMMU device using
virtio transport. It contains a description of the device, a Linux driver,
and a toy implementation in kvmtool. With this prototype, you can
translate DMA to guest memory from emulated (virtio), or passed-through
(VFIO) devices.
In its simplest form, implemented here, the device handles map/unmap
requests from the guest. Future
