Storage Feature Tables

This page summarizes storage features available in Abiquo and using different storage types.

The information on this page applies to private cloud only

Hypervisor Datastores

Hypervisor	Datastore	Notes
ESXi	VMFS NFS with RDM	RDM property Abiquo Configuration Properties#esxi
Hyper-V	local disk SMB mounted disk CSV	Do not use C:\
KVM	local disk	Do not use /
Oracle	NFS required
XenServer	LVM, EXT3, NFS, iSCSI, HBA

Abiquo detects datastore disk changes

Abiquo periodically checks hypervisors for changes in virtual machines, including CPU, RAM and datastore disks. You can set an abiquo.property to control the frequency of these checks (abiquo.vsm.vmsyncfrequency.<PLUGIN> see Abiquo Configuration Properties#vsm). If a virtual machine datastore disk is resized, Abiquo updates the size registered in Abiquo. If Abiquo detects a change in the datastore used for the virtual machine primary disk, it updates the value in Abiquo and publishes the following tracer:

Datastore of virtual machine '{VIRTUAL_MACHINE_NAME}' has been changed from '{OLD_VALUE}' to '{NEW_VALUE}'.

Abiquo support for storage moves and motion is described in the tables for each hypervisor.

iSCSI Storage Volumes

In Abiquo all iSCSI storage is persistent, i.e. changes persist after the virtual machine is undeployed. NFS storage is also persistent.

Datastore Hard Disks

Datastore Hard Disks are not persistent. When the user undeploys a virtual machine with disks on the hypervisor datastore, these disks will be destroyed.
