| suggested "If the IOS are not split evenly between VMs, you could use some tool like
| |
| dm-ioband<ref>http://sourceforge.net/apps/trac/ioband/wiki/dm-ioband</ref> to make sure IOs are split fairly between VMs. Or then get faster disks. Single 15k rpm SAS disk will give you up to 350
| |
| IOPS, so it's 2-3x faster than 7200 rpm SATA."

| "For KVM, each VM isn't really any different from a host process, so
| |
| you have to deal with them the same way that you'd deal with having

| lots of host processes doing I/O. So: lots of spindles, expensive I/O

| === Virtualization Tools List ===
| |
| This section contains the discussion happening on the
| |
| [http://www.redhat.com/mailman/listinfo/virt-tools-list virt-tools-list list].
| |
| | |
| The very newest releases of virt packages are available (for testing purposes only) in the [[Virtualization Preview Repository]] before they become generally available.
| |
| | |
| ==== New Release virt-manager 0.8.0 ====
| |
| [[ColeRobinson|Cole Robinson]]
| |
| <ref>http://www.redhat.com/archives/virt-tools-list/2009-July/msg00054.html</ref> | |
| a new {{package|virt-manager}}<ref>http://virt-manager.org/</ref> release, version 0.8.0.
| |
| | |
| Virtual Machine Manager provides a graphical tool for administering virtual machines, using {{package|libvirt}} as the backend management API.
| |
| | |
| '''New features:'''
| |
| * New 'Clone VM' Wizard
| |
| * Improved UI, including an overhaul of the main 'manager' view
| |
| * System tray icon for easy VM access (start, stop, view console/details)
| |
| * Wizard for adding serial, parallel, and video devices to existing VMs.
| |
| * CPU pinning support (Michal Novotny)
| |
| * Ability to view and change VM security (sVirt) settings (Dan Walsh)
| |
| * Many bug fixes and improvements

| ==== New Release virtinst 0.500.0 ====
| |
| [[ColeRobinson|Cole Robinson]]
| |
| announced<ref>http://www.redhat.com/archives/virt-tools-list/2009-July/msg00055.html</ref>
| |
| a new {{package|python-virtinst}} release, version 0.500.0.
| |
| | |
| <code>virtinst</code> is a module that helps build and install <code>libvirt</code> based virtual machines. It currently supports <code>KVM</code>, <code>QEmu</code> and <code>Xen</code> virtual machines. Package includes several command line utilities, including <code>virt-install</code> (build and install new VMs) and <code>virt-clone</code> (clone an existing virtual machine).
| |
| | |
| '''New features:'''
| |
| * New virt-install device options --serial, --parallel, and --video
| |
| * Allow various auth types for libvirt connections (PolicyKit, SASL, ...)
| |
| * New virt-clone option --auto-clone: generates all needed input.
| |
| * Option to specify network device model via virt-install --network (Guido Gunther)
| |
| * New virt-install option --virt-type for specifying hypervisor type (kvm, qemu). --accelerate is now the default behavior: To provision a plain qemu VM on a KVM enabled host, use '--virt-type qemu'
| |
| * OVF input support for virt-convert
| |
| * Many bug fixes and improvements

| ==== New Release virt-viewer 0.2.0 ==== | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| [[DanielBerrange|Daniel Berrange]]
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| announced<ref>http://www.redhat.com/archives/virt-tools-list/2009-July/msg00059.html</ref>

| |
|
| |
|
| '''New features:'''
| | [[DanielBerrange|Daniel Berrange]] |
| * Switch UI over to use Glade
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| * Support graphical dialog for VNC and libvirt authentication
| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| * Resize window to match VNC desktop size where possible
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| * Scale down VNC desktop if it cannot fit in host desktop space
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| * Allow user to resize window to arbitrary size, scaling VNC
| | also pretty close to that using what's best described as a hybrid of |
| * Fix blocking of accelerators
| | kvm-83 and kvm-84." |
| * Allow automatic reconnect to a VM via --reconnect
| |
| * Use libvirt events to detect when VM changes state
| |
| * Wait for VM to appear if it does not exist
| |
| * Fix plugin build with newer xulrunner
| |
| * Port & build for Mingw32 target
