Introduction to vMotion

When you use vCenter hosts, Abiquo supports vMotion with the capabilities functionality and limitations described belowhere. 

...

Abiquo supports this vMotion functionality for vCenter hosts:

• The events are detected properly independently of the polling interval, which only affects the state change detection velocity.

• False DESTROYED/CREATED events are detected (and not propagated) using

  VCenter

  vCenter to check if the

  virtual machine

  VM has vMotion or Relocation tasks in progress.

• Abiquo detects vMotion movements (

  virtual machines

  VMs in power on)

• Abiquo detects Relocation movements (

  virtual machines

  VMs in power off)

• In early tests,

  Abiquo detects movements produced by

  VMWare

  VMware DRS

  because

  (and it properly manages the repeated names of virtual machines in the caches

  .

• Abiquo supports vMotion between different versions of ESXi
  

...

Limitations of vMotion in Abiquo

Abiquo works with vMotion with the following limitations:

• MOVED events are not propagated when the

  virtual machine

  VM is moved to a host in vCenter that is not managed by Abiquo

  (it is not added to Abiquo and not monitored by the Monitor Manager/Virtual System Monitor) but it is managed by vCenter. The virtual machine

  . The VM will remain with the last known state. Then:

  • if

    If the destination host is added to Abiquo, a MOVED event will be generated properly.

  • if

    If the

    virtual machine

    VM goes back to the original host, its state will be updated

    .
  VMWare HA is not supported

  • .

• Abiquo

  does not support

  supports movements between machines with different Network Service

  Types unless

  Types if the machines are connected to a dvSwitch. 

  You must configure the same network service type for source and destination machine network interfaces or you will not be able to use the moved VM in Abiquo.

  • dvSwitch :

      Abiquo

     Abiquo will only allow you to change the Network Service Type of a dvSwitch if there are no

    virtual machines

    VMs deployed on any of the

    machines

    hosts attached to that dvSwitch. 

• Abiquo supports Storage vMotion to the same

  ESX host is supported since version 3.0

  ESXi host

  • When you are performing a vMotion operation, vCenter asks if you want to migrate the datastore on which the VM is located. If you vMotion a VM to the same host and you just change the destination datastore, this will work in vCenter and Abiquo will detect it when it synchronizes the

    virtual machine

    VM definition. You can set the frequency of this check with the abiquo.vsm.vmsyncfrequency.vmx_04 property. See Abiquo

    Configuration Properties#vsm

vMotion Configuration Requirements

The following vMotion configuration requirements are explained below:

• Abiquo properties
• Shared datastore on VMWare
• Shared datastore enabled in Abiquo

Configuring Abiquo Properties for vMotion

In order to detect movements, the Monitor Manager requires the following Abiquo Configuration Properties for DvS and vCenter. Set these properties in the abiquo.properties file on the Remote Services machine.

• abiquo.dvs.vcenter.user
• abiquo.dvs.vcenter.password
• abiquo.vcenter.port.connection

Configuring iSCSI Shared Storage

On the storage device, check you have properly configured the initiator group to include each ESX/ESXi, by adding the hypervisors' IQNs to the list.
Also remember to add the Abiquo IQN, which can be found at /etc/iscsi/initiatorname.iscsi

NetApp

For example, for NetApp, open the Filer WebUI at http://<Filer_IP>/na_admin/ then click the FilerView button.

If you have previously used the NetApp storage with an ESX/ESXi host outside of Abiquo, the ESX/ESXi host's IQN will probably have been added to another initiator group. You will need to manually remove it from that group before you can use it in Abiquo. You can add it to abiGroup manually or Abiquo will add it automatically.

Configuring the Hypervisor to Use a Shared VMFS Datastore

...

• • configuration properties for vsm

You must have the following configuration for vMotion:

• Shared datastore on VMware

• Shared datastore enabled in the platform

This configuration is explained below.

...

Configure a shared VMFS datastore

To get vMotion® working with Abiquo you need to ensure that all the hypervisor hosts have a shared VMFS datastore.To do this, first create

1. Create a volume (that will be shared by all your

...

1. ESXi hypervisors) in your preferred storage system

...

2. Add it to an

...

1. ESXi hypervisor using the static discovery method.

1. From the iSCSI Software Adapter properties window

1. , go to Static Discovery

2. Complete the dialog

1. with the server hostname or IP and the target IQN. The port should be the default, which is 3260.

Enabling the Shared Datastore in Abiquo

When adding the your hypervisors to Abiquo make sure , check that the newly created shared datastore is visible, and activatedenable it.Image Removed
