Using Hyper-V Export for Backups

Using Hyper-V Export for Backups

One of the benefits of virtualized systems is the portability of the guest machines. At their core, they are nothing more than a collection of files. What the guest machines believe to be their “hard drives” are actually .VHD files. Their “hardware components” are determined by a list stored in an XML file. At this time, the files can’t simply be copied from one point to another without some fairly involved work, but the “Export” command can be used to prepare the VM and copy its data to another location. This also provides a rudimentary form of backup.  (more…)

Choosing a Hyper-V Installation Option – Native or as a Role in Windows Server Core or Full

Choosing a Hyper-V Installation Option – Native or as a Role in Windows Server Core or Full

One of Hyper-V’s unique attributes is that it has dramatically different deployment options. You can install it natively directly to host hardware, or you can install a copy of Windows Server and enable Hyper-V as a role. Within the Server option are two more choices: Full or Core. There are perfectly valid reasons to choose any of these three deployment options.  The decision is fairly permanent, though, so take the time to make an educated decision prior to deployment.

Hyper-V Terminology – Host Operating System or Parent Partition?

Hyper-V Terminology – Host Operating System or Parent Partition?

As the field of virtualization developed, two overall classifications emerged: type 1 and type 2. As the products continued to mature, the distinctions began to blur. As a result, some terminology has begun to be used interchangeably even though it was originally meant for two very different things. A case in point is “Host Operating System” as opposed to “Parent Partition”. These terms are actually different and using the “wrong” one can sometimes lead to a heated debate. When it comes to terminology, the most important thing is ensuring that you and your audience know what you mean, even if the words may not be exactly right. However, there is never any harm in learning the history of your vocabulary. (more…)

Enabling Hyper-V Guest Console in Server Core

Enabling Hyper-V Guest Console in Server Core

In Server Core, no Hyper-V Guest console is provided and you need to use the remote server Hyper-V Manager snap-in or VMM Console to manage a Virtual machine. I just found a free tool to execute the Hyper-V Guest Console in Server Core. Let see how you can enable the Hyper-V Guest Console in Server Core itself.

SBS 2011 Backups Failing – VSS Error 0x800423F3 – Event ID 8230 (spfarm, spsearch)

A customer using Altaro Hyper-V Backup on Windows 2008 R2 Enterprise SP 1 contacted us because attempts to back up a virtual machine that had Small Business Server 2011 (SBS) installed were failing due to a VSS error.

We began troubleshooting by collecting the Altaro Error Logs, Windows Application and System Event Logs, and a dump of the VSS Writers and Providers from the Hyper-V host. (more…)
