Virtualization

Convert from VirtualBox to KVM/Qemu

Konverting from VirtualBox to KVM is actually quite easy.

If you use snapshots in VirtualBox, then you will first have to clone the current running state into a new VM (Right clickt -> Clone -> blah -> select only current state)

Then, if you use dynamic growing disks, convert them to raw format

VBoxManage clonehd --format RAW Win7.vdi Win7.raw

Now convert it to qcow2

Project T5220, try 1: How NOT to configure a T5220 as a complete Oracle/Weblogic development environment

Currently I have to configure a Sun Enterprise T5220 as our new "developemnt environment", replacing our V440 (Oracle) and the T1000 (Weblogic). We chose a Sun CMT machine as we wanted to stay close to production in regards of architecture (processor type/OS etc).

The machine will have to run an Oracle instance, and some containers for the Weblogic environments (we have an integration env, daily build env + some development environments for projects). The new T5220 ist packed with a 1.4GHz T2 Niagara, 64GB of memory, 2x146GB for the OSes, and 6x300GB for the database and NFS.
