Other Improvements

Need to pick improvements from release notes above.

virt-manager Updated to 0.400.0

https://www.redhat.com/archives/et-mgmt-tools/2008-September/msg00027.html New features:

• New tool 'virt-convert': Allows converting between different types of virt configuration files. Currently only supports vmx -> virt-image.
• New tool 'virt-pack': Converts virt-image xml format to vmx and packs in a tar.gz. (Note this will likely be merged with virt-convert in the future).
• virt-install: Support for remote VM installation. Can use install media and disk images on remote host if shared via libvirt. Allows provisioning storage on remote pools.
• virt-install new options:

     new --wait option, allows putting a hard time limit on installs.
     new --sound option, to create VM with soundcard emulation.
     new --disk option, allows specifying media as a path, storage volume, or
       a pool to provision storage on, device type, and several other options.
       Deprecates --file, --size, --nonsparse.
     new --prompt option. Input prompting is no longer the default, this
       option turns it back on.

• virt-install: allow setting cpu pinning information for qemu/kvm VMs.
• virt-install: numa support via --cpuset=auto option.
• virt-image: --replace option to overwrite existing VM image file.
• virt-image: support multiple network interfaces in virt-image format.
• use virtio disk/net drivers if chosen os entry supports it (Fedora 9/10, Ubuntu Hardy).
• Numerous bug fixes and minor improvements.

libvirt Updated to 0.4.6

New features and improvments since 0.4.2:

• Enhanced OpenVZ support
• Enhanced Linux containers (LXC) support
• Storage pools API
• Improved iSCSI support
• USB device passthrough for QEmu and KVM
• Sound, serial, and parallel device support for QEmu and Xen
• Support for NUMA and vCPU pinning in QEmu
• Unified XML domain and network parsing for all virtualization drivers

For further details see: http://www.libvirt.org/news.html

Xen Updated to 3.3.0

This is a major new release with a host of new features including:

• Power management (P & C states) in the hypervisor
• HVM emulation domains ('qemu-on-minios') for better scalability, performance and security
• PVGrub: boot PV kernels using real GRUB inside the PV domain
• Better PV performance: domain lock removed from pagetable-update paths
• Shadow3: optimisations to make this the best shadow pagetable algorithm yet, making HVM performance better than ever
• Hardware Assisted Paging enhancements: 2MB page support for better TLB locality
• CPUID feature levelling: allows safe domain migration across systems with different CPU models.
• PVSCSI drivers for SCSI access direct into PV guests
• HVM framebuffer optimisations: scan for framebuffer updates more efficiently
• Device passthrough enhancements
• Full x86 real-mode emulation for HVM guests on Intel VT: supports a much wider range of legacy guest OSes
• New qemu merge with upstream development
• Many other changes in both x86 and IA64 ports
