+Command Line Changes for Reduced Binary Size # The clap crate was replaced by the argh crate to create our command line, which reduced our release binary size from 3.6MB to 3.3MB. There were several syntax changes:
+All --option=value commands now are --option value. The --disk DISK1 DISK2 command now is --disk DISK1 --disk DISK2.</description></item><item><title>Cloud Hypervisor v29.0 Released!</title><link>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v29.0-released/</link><pubDate>Sat, 14 Jan 2023 12:46:39 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/cloud-hypervisor-v29.0-released/</guid><description>This release has been tracked in our roadmap project as iteration v29.0.

 Bypass Mode for virtio-iommu # virtio-iommu specification describes how a device can be attached by default to a bypass domain. This feature is particularly helpful for booting a VM with guest software which doesn&amp;rsquo;t support virtio-iommu but still need to access the device. Now that Cloud Hypervisor supports this feature, it can boot a VM with Rust Hypervisor Firmware or OVMF even if the virtio-block device exposing the disk image is placed behind a virtual IOMMU.</description></item><item><title>Achieving Bare Metal Performance Within a Virtual Machine</title><link>https://www.cloudhypervisor.org/blog/achieving-bare-metal-performance-within-a-virtual-machine/</link><pubDate>Thu, 19 May 2022 08:00:00 +0000</pubDate><guid>https://www.cloudhypervisor.org/blog/achieving-bare-metal-performance-within-a-virtual-machine/</guid><description>There are use cases for which a workload needs to access specific hardware such as accelerators, GPU or network adapters to maximise potential performance. And since these workloads run inside virtual machines (VM) for security reasons, the challenge is to make this hardware available from within the VM, but without degrading the performance that can be achieved from bare metal.
