Is shared storage required for live migration?
Key benefits. Live migration of virtual machines in Windows Server 2012 delivers improved performance and flexibility. It is also now available inside and outside of clustered environments—both with and without shared storage.
Does Hyper-V support live migration?
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. The primary benefit of live migration is flexibility; running Virtual Machines are not tied to a single host machine.
Under what conditions would live migration not work?
VM failed to live migrate because a virtual switch used by the VM doesn’t exist on the destination node “Host2”. The virtual switch must have the same name on all nodes. If a virtual machine is connected to a virtual switch that doesn’t exist on the destination node, then live migration fails at < 10%.
What is shared nothing migration?
Shared nothing live migration is a feature of Microsoft Hyper-V 3.0 and VMware vSphere 5.1 that allows a virtual machine (VM) to be moved from one physical server with direct-attached storage to another physical server with direct-attached storage.
Can we migrate running virtual machines without shared storage?
vMotion does not require environments with shared storage. This is useful for performing cross-cluster migrations, when the target cluster machines might not have access to the storage of the source cluster. Processes that are working on the virtual machine continue to run during the migration with vMotion.
How do I move a VM from one host to another without vMotion?
Yes, that’s exactly what you need to do.
- Turn VM off on Host 1.
- “Remove from Inventory” on Host 1.
- Go to Host 2 and browse datastore.
- Right click on VMX file for VM and “Add to Inventory”.
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 migration?
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 might cause a virtual machine migration to fail?
Mismatched Hyper-V versions, iSCSI incompatibility and slow network connections. Mismatched versions of Hyper-V within a failover cluster could also cause a live migration to fail. A cluster can consist of multiple Windows Server editions, as long as each copy of Windows Server belongs to the same release cycle.
What is the difference between live migration and storage migration?
What is shared nothing vSphere vMotion?
Introduced in vSphere 5.1, shared nothing migrations allow the user to vMotion and svMotion a virtual machine across environments that don’t have shared storage. This ability can be extremely useful in infrastructures that remain on local storage and still want to leverage the flexibility of migrating workloads.
Does Hyper-V or SCVMM work best for migrations?
Joseph Moody is a network admin for a public school system and helps manage 5,500 PCs. He is a Microsoft Most Valuable Professional (MVP) in Cloud and Datacenter Management and blogs at DeployHappiness.com. For the most part, live migrations in Hyper-V or System Center Virtual Machine Manager (SCVMM) work flawlessly.
What is a shared nothing live migration?
(This is sometimes referred to as a “shared nothing” live migration. In this case, the virtual machines storage is mirrored to the destination server over the network, and then the virtual machine is migrated, while it continues to run and provide network services.
How do I configure Hyper-V manager for live migrations?
Open Hyper-V Manager if it is not already open. (From Server Manager, click Tools and then click Hyper-V Manager .) In the navigation pane, select one of the servers that you want to configure for live migrations. (If none of the servers are listed, click Hyper-V Manager in the navigation pane.
Why is my Hyper-V Live Migration not sending or receiving?
Start by checking your Hyper-V live migration settings on the source and destination hosts. When these options are left as unconfigured, you may receive an error message stating that the destination computer is not configured to send or receive live migrations of virtual machines.
