lead></p><p>This release has been tracked through the
<a href=
https://github.com/cloud-hypervisor/cloud-hypervisor/projects/13>0.10.0 project
</a>.
</p><p>Highlights for
<code>cloud-hypervisor
</code> version 0.10.0 include:
</p><h3 id=
virtio-block-support-for-multiple-descriptors><code>virtio-block
</code> Support for Multiple Descriptors
<a href=
#virtio-block-support-for-multiple-descriptors class=
anchor aria-hidden=
true>#
</a></h3><p>Some
<code>virtio-block
</code> device drivers may generate requests with multiple descriptors and support has been added for those drivers.
</p><h3 id=
memory-zones>Memory Zones
<a href=
#memory-zones class=
anchor aria-hidden=
true>#
</a></h3><p>Support has been added for fine grained control of memory allocation for the guest. This includes controlling the backing of sections of guest memory, assigning to specific host NUMA nodes and assigning memory and vCPUs to specific memory nodes inside the guest. Full details of this can be found in the
<a href=
docs/memory.md>memory documentation
</a>.
</p><h3 id=
seccomp-sandbox-improvements><code>Seccomp
</code> Sandbox Improvements
<a href=
#seccomp-sandbox-improvements class=
anchor aria-hidden=
true>#
</a></h3><p>All the remaining threads and devices are now isolated within their own
<code>seccomp
</code> filters. This provides a layer of sandboxing and enhances the security model of
<code>cloud-hypervisor
</code>.
</p><h3 id=
preliminary-kvm-hyperv-emulation-control>Preliminary KVM HyperV Emulation Control
<a href=
#preliminary-kvm-hyperv-emulation-control class=
anchor aria-hidden=
true>#
</a></h3><p>A new option (
<code>kvm_hyperv
</code>) has been added to
<code>--cpus
</code> to provide an option to toggle on KVM’s HyperV emulation support. This enables progress towards booting Windows without adding extra emulated devices.
</p><h3 id=
