What is the difference between Quick Migration and live migration?
The only difference between ‘Quick Storage Migration’ and ‘Live Migration’ is that the first one moves virtual machine storage from one location to another location and later one is capable of moving virtual machine along with the storage from one node to another node in the cluster.
How do I enable live migrations?
Use Hyper-V Manager to set up the source and destination computers for live migration
- Open Hyper-V Manager.
- In the navigation pane, select one of the servers.
- In the Action pane, click Hyper-V Settings >>Live Migrations.
- In the Live Migrations pane, check Enable incoming and outgoing live migrations.
What does live migration refer to in Windows Server 2012?
Live migration is a Hyper-V feature in Windows Server. It allows you to transparently move running Virtual Machines from one Hyper-V host to another without perceived downtime.
What is a requirement for live migration?
Requirements for live migration using shared storage: All files that comprise a virtual machine (for example, virtual hard disks, snapshots, and configuration) are stored on an SMB share. Permissions on the SMB share have been configured to grant access to the computer accounts of all servers running Hyper-V.
How does VM live migration work?
Live migration takes place between two Hyper-V hosts. Essentially, the VM memory is copied between Hyper-V hosts. After the memory is copied, the VM on the new host can access its virtual hard disk (VHD) files and continue to run. Both hosts access shared storage where the VM’s VHD files are stored.
Why is it necessary to migrate a virtual machine?
Migration of virtual machine is gaining more importance today to improve utilization of resources, load balancing of processing nodes, isolation of applications, tolerating the faults in virtual machines, to increase the portability of nodes and to rise the efficiency of the physical server.
What Authentication Protocol does live migration use by default?
Kerberos
To manage the tasks with remote management tools, configure constrained delegation and select Kerberos as the authentication protocol. Otherwise, you must sign on to the source computer to perform a live migration, and CredSSP is used to authenticate the live migration.
How long does live migration take?
The length of time it takes to complete depends on the size and activity of the VM, as well as the speed and activity of the network connection between the Hyper-V host systems. Typically, my network live migrations take between about 10 seconds and a minute.
What are the uses of VM live migration?
Live migration allows you to: Automatically optimize virtual machines within resource pools. Perform hardware maintenance without scheduling downtime or disrupting business operations. Move virtual machines away from failing or underperforming servers.
What type of instances can be live migration?
Live migration keeps your instances running during:
- Regular infrastructure maintenance and upgrades.
- Network and power grid maintenance in the data centers.
- Failed hardware such as memory, CPU, network interface cards, disks, power, and so on.
- Host OS and BIOS upgrades.
How many steps are involved in live migration of VM?
As shown in Figure 3.20, live migration of a VM consists of the following six steps: Steps 0 and 1: Start migration. This step makes preparations for the migration, including determining the migrating VM and the destination host.
What does live migration do in Windows Server?
Live migration is a Hyper-V feature in Windows Server. It allows you to transparently move running Virtual Machines from one Hyper-V host to another without perceived downtime.
What is Windows Server 2012 Hyper-V Live Migration?
Windows Server 2012 introduces SMB 3.0 – an economic, continuously available, and scalable storage strategy that is supported by Windows Server 2012 Hyper-V. Live Migration supports storing virtual machines on SMB 3.0 shared storage.
What do you need to know about live migration?
Live Migration Overview. Live migration is a Hyper-V feature in Windows Server. It allows you to transparently move running Virtual Machines from one Hyper-V host to another without perceived downtime.
What are the benefits of live migration for virtual machines?
The primary benefit of live migration is flexibility; running Virtual Machines are not tied to a single host machine. This allows actions like draining a specific host of Virtual Machines before decommissioning or upgrading it.
