If you’ve built a VMware VM but forgotten to turn off LVM and therefore cant use vmware virtual toolbox to shrink your disks you can still perform a virtual shrink by filling up your vm vmdks with 0’s !
$ dd if=/dev/zero bs=40M count=40 of=1
$ dd if=/dev/zero bs=40M count=40 of=2
$ dd if=/dev/zero bs=40M count=40 of=3
$ dd if=/dev/zero bs=40M count=40 of=4
$ dd if=/dev/zero bs=40M count=40 of=5
etc etc
$ rm 1 2 3 4 5
This didnt affect the 11G of space used by my vm vmdk disks but it did reduce the tgz of the entire vm from 5.5G to 3.3G !
Eucalyptus Enterprise Edition (Eucalyptus EE) with vSphere® support enables customers to implement on-premise cloud computing with Eucalyptus, the most popular open source private cloud software, and vSphere, VMware’s industry-leading virtualization platform. Eucalyptus EE with vSphere support is the only on-premise cloud computing solution available today for vSphere customers, providing a robust, affordable cloud computing solution that leverages their investment in VMware® technologies.
Patrick Kerpan gave a great talk this evening on Elastic Server Bundles. You can just search for a component name such as java to get a list of bundles which you can then add to your server template and then create your Server image on a variety of virtualisation and cloud platforms. I particularly liked the idea of using Elastic Server to create KVM images for your dev team, VMW images for your test team and AMI for operations / production !
NewServers have created a cloud that doesn’t use virtualisation ! NewServers explain that
all of the other server clouds use virtualization. They use a Hypervisor that allows them to run operating systems inside an operating system. They use this to create many virtual private servers (VPS) on the same physical server and sell those to different customers. This introduces overhead that significantly affects network and disk operations. The technology is far from perfect introduces additional security risks. Users on a shared server can affect one another’s performance.
and that NewServers
have nothing against virtualization. We do have something against sharing. You don’t share your personal computer so why would share the one that runs your business critical applications. Instead of selling ambiguously defined and potentially dynamic slices of servers we sell absolute whole units and grant access down to the bare metal. You’re free to use virtualization if you wish; we even have prebuilt VMware images in our catalog.
VMware Player 3 has a bundle of new features:
Amazon EC2 has just announced the ability to boot instances directly from Amazon EBS snapshots, providing increased flexibility in how customers can manage their instances.
You can still save an Amazon Machine Image (AMI) in an Amazon S3 bucket and boot it from the local instance store, but you can now also choose to save AMIs as Amazon EBS snapshots and boot directly from an Amazon EBS volume.
http://www.redmondpie.com/how-to-install-chrome-os-in-windows-7-9140127/ has a great link to some pre-built vmdk virtual machines of Google Chrome OS from gdgt ! However you will need to create a gdgt account before you can download them !
The latest version of Eucalyptus features new multi-cluster support and enhanced concurrency management for improved scaling, enabling users to seamlessly overlay their Eucalyptus cloud on top of virtually any existing IT infrastructure, regardless of size or configuration.
