Hi,
This patch series is to enable Kimchi to assign host PCI devices
directly to a VM, thus greately improve VM performance. For example,
pass through a NIC to VM to improve guest network throughput, or pass
through a video card to VM to enable the guest OS to run 3D video
games.
Firstly, the user should be able to list all host devices in a tree, so
as to determine which PCI devices should be passed through. Once a PCI
device is assigned to VM, all the sub-device connected to it would be
also assigned to VM. The device listing and device tree formatting is
implemented in the patch "list all types of host devices" and "list all
host devices in a tree".
Secondly, the user should be able to pass the names of the host PCI
devices to a VM template. Then the user can create a VM from the
template, and the PCI devices would be automatically assigned to the VM
when it starts, and automatically released when the VM is powered off.
This is implemented in the patch "pass through PCI device to VM".
The author also fixed a bug in VM template during the test. The fix is
in patch "add disk size error message".
All the patches are for back-end. The detailed implementation and
testing method are written in the patch commit messages.
