Cloud Hypervisor driver
|
||
|
=======================

Cloud Hypervisor is an open source Virtual Machine Monitor (VMM) that
|
||
|
runs on top of KVM. The project focuses on exclusively running modern,
|
||
|
cloud workloads, on top of a limited set of hardware architectures and
|
||
|
platforms. Cloud workloads refers to those that are usually run by
|
||
|
customers inside a cloud provider. For our purposes this means modern
|
||
|
operating systems with most I/O handled by paravirtualised devices
|
||
|
(i.e. virtio), no requirement for legacy devices, and 64-bit CPUs.
|
||
|
|
||
|
The libvirt Cloud Hypervisor driver is intended to be run as a session
|
||
|
driver without privileges. The cloud-hypervisor binary itself should be
|
||
|
``setcap cap_net_admin+ep`` (in order to create tap interfaces).
|
||
|
|
||
|
Expected connection URI would be
|
||
|
|
||
|
``ch:///session``
|
||
|
|
||
|
|
||
|
Example guest domain XML configurations

=======================================
|
||
|
|
||
|
The Cloud Hypervisor driver in libvirt is in its early stage under active
|
||
|
development only supporting a limited number of Cloud Hypervisor features.
|
||
|
|
||
|
Firmware is from
|
||
|
`hypervisor-fw <https://github.com/cloud-hypervisor/rust-hypervisor-firmware/releases>`__
|
||
|
|
||
|
**Note: Only virtio devices are supported**
