VMware Tools Virtual Shrink

December 11th, 2009

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 !

Elastic Server Bundles

December 8th, 2009

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 !

Bare Metal Cloud

December 7th, 2009

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.

Amazon EC2 can now boot from Amazon EBS snapshots

December 4th, 2009

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.
