What is VM redundancy?
Redundancy for your Virtual Machines (VMs) Clustering will let you restart a service or application on the same host, but also move it to a different host if there continues to be an availability or reliability issues.
Does Hyper-V support virtualization?
Hyper-V specifically provides hardware virtualization. That means each virtual machine runs on virtual hardware. Hyper-V lets you create virtual hard drives, virtual switches, and a number of other virtual devices all of which can be added to virtual machines.
How do you configure an existing VM for high availability?
How to Make an Existing Hyper-V VM Highly Available
- Open the Failover Cluster Manager.
- In the left pane, right-click Roles and select Configure Role.
- The High Availability Wizard should open.
- In the Select Role section, click Virtual Machine to enable Hyper-V High Availability for specific VMs.
Does Hyper-V support fault tolerance?
Hyper-V itself has no true fault tolerance capability. The main thing to note is that Hyper-V has no ability to continue running a virtual machine on a host that crashes without interruption to the virtual machine.
What is Hyper V High Availability?
The term means that VMs should be available, regardless of the availability of the physical host it is running at. There are some specific methods for ensuring HA of the VMs. Specifically, I’d like to talk about failover clustering, which is Microsoft’s native feature for Windows Server with a Hyper-V role enabled.
Which one is used to recover VMs in the event of a failure?
Failover clusters are used to protect VMs in case of hardware failure, providing high availability for critical VMs. If one of the hosts within cluster fails, then the VMs that were running on the failed host migrate to other, healthy hosts in the failover process.
Is VirtualBox better than Hyper-V?
VirtualBox is what you’d use for directly working with a VM, especially if you need sound, USB, and a very wide range of supported OSes. Hyper-V is designed to host servers where you don’t need a lot of extra desktop hardware (USB for example). Hyper-V should be faster than VirtualBox in a lot of scenarios.
What happens if I turn off Hyper-V?
Affected applications include VMware Workstation and VirtualBox. These applications might not start virtual machines, or they may fall back to a slower, emulated mode. These symptoms are introduced when the Hyper-V Hypervisor is running.
What is Hyper-V High Availability?
How does Hyper-V failover cluster work?
Failover cluster is a set of several similar Hyper-V servers (called nodes), which can be specifically configured to work together, so that one node can take the load (VMs, services, processes) if another one goes down or if there is a disaster.
What is enable replication in Hyper-V?
Hyper-V Replica is a free in-built feature in Hyper-V 3.0 for disaster recovery. Hyper-V replication enables you to set up a Virtual Machine to replicate from one Hyper-V host to another Hyper-V Host which you can recover easily within minutes in case of a disaster.
Can a Hyper-V host have more than one VM?
These VM licenses aren’t tied to the OS in the virtual machine. You can have 2 2012 R2 servers each running 1 VM and each will be allowed to to license an additional VM as long as the host is only used for Hyper-v. So Server A hosts VM A and Server B hosts VM B.
What do you need to know about Hyper V clustering?
Hyper-V clustering, or ESXi with HA/DRS will allow you to consolidate servers for ‘failover’ capabilities; hyper-V for the guestOSes and ESXi for HA of the virtual machines (specifically virtual hardware; guestOS will reboot). As far as I understand, Hyper V clustering involves some sort of SAN storage.
Can a Hyper-V Server host a virtual domain controller?
Use SCSI physical drives (as opposed to IDE/ATA drives) on Hyper-V servers that host virtual domain controllers. If you cannot use SCSI drives, ensure that write caching is disabled on the ATA/IDE drives that host virtual domain controllers.
Which is an example of a high availability virtualization system?
3. Automatic Failover– Protects against host system failure by automatically moving virtual machines from a primary host that has failed to a secondary host. This capability is commonly referred to as “High Availability” and is essential when your virtual machines are critical. Figure 1 – Example DeltaV Virtualization System
