Next week Berlín will host two of the most important Linux events in Europe: LinuxCon and ContainerCon. The first one gathers experts from all over the world that mantain, develop and lead the most important projects in the Linux community. And the second one, which runs concurrent, is the perfect scenario to share specific technical knowledge on cloud computing and Linux containers.
Before upgrading a virtual machine, it is recommended to make a snapshot to be able to revert a Domain/VM to a snapshot in case an error occurs during the upgrading process. There is a command to create a snapshot of a Virtual Machine (VM) while it is running.
A Logical Volume manager (LVM) for Linux enables to manage disk space in a very flexible way. It allows to add disk space to a logical volume and its filesystem while such filesystem is mounted and active. It provides the ability to collect multiple physical hard drives and partitions in a single volume group that can be divided into logical volumes.
Hyper-converged infrastructures simplify desktop virtualization, since all back-end resources, including management software, run together on an isolated and completely integrated location.
Therefore, these systems can change the way an organization approaches VDI, as they reduce IT workloads and makes it easier to fix issues related to data center.
Migrating from one vCenter to another has been so far a hard task, since it was pretty difficult to deploy and configure a new vCenter Server while keeping the existing one to perform the migration. When performing this task, one should take into account many factors, as the sieze of the environment, the number of solutions using vCenter Server as an endpoint and hoy physical and virtual networks are configured. Drafting the full migration of a virtual infrastructure plan may also take a long time.
But now, it’s going to be far more easy, since VMware has announced the release of vSphere 6.0 Update 2m (Migration), an automate tool to migrate from a vCenter Server 5.5 Windows to vCenter Server Appliance 6.0 Update 2.
