ensure that your VM templates will deploy properly to VMs. Follow the guidance below on your VMs before you save their disks as VM templates. |
You can use any virtual disk in a supported format as a template to deploy VMs in Abiquo - see Template compatibility table.
You can also check To create a VM template, you can install an operating system on a VM deployed directly on a hypervisor and then save the virtual disk file (or OVA) to load into Abiquo to share with your users.
As a guide, you can check many of the available settings for VM templates when you edit a VM template (especially, on the Advanced tab). See https://abiquo.atlassian.net/wiki/spaces/doc/pages/311371311/Modify+a+VM+template#Edit-template-advanced-tab.
To create a VM template, you can install an operating system on a VM deployed directly on a hypervisor, and then save the virtual disk file or OVA, and load it into Abiquo as a VM template.
To ensure that your VM templates will deploy properly to VMs, follow the guidance below on your VMs before you load them as VM templates and make them available to your cloud users.

Abiquo may also recognize some additional hardware from the OVF file (within an OVA). See OVF reference.

Virtual disk formats
You can use any virtual disk in a supported format as a template to deploy VMs in Abiquo - see Template compatibility table.
VM Templates can be very large and flat formats can have a size equal to the total virtual disk capacity. To minimize download overhead when distributing a VM template, convert it to a compressed format like VMDK-streamOptimized or QCOW2-compressedSparse.

VM disk controllers
Hard disks
By default, Abiquo attaches VM system disks to IDE controllers on all hypervisors.
...
When Abiquo deploys VMs with SCSI controllers, it uses the LSILogic SCSI controller by default. Abiquo supports additional SCSI controllers. You can configure SCSI disk controllers using Abiquo configuration properties.
DVDs
Abiquo supports ISO disks and DVDs with ISO disks. You can also attach these disks within Abiquo when you edit a VM template.
...
VM Networks
Virtual network adapters
By default Abiquo uses Intel E1000 network drivers which are highly compatible with all systems. Abiquo also supports PCNet32 and VMXNET3 drivers on VMware, and VIRTIO drivers on KVM.
Configure networking to use DHCP
Select dynamically-assigned IP addresses in your default VM configuration to ensure that your VMs all receive different IP addresses! 
Erase MAC addresses from network scripts
Some operating systems, such as Red-Hat, store your VM’s MAC addresses in their network initialization scripts. Abiquo assigns a new MAC when you deploy a VM from a template, but any old network script with an old MAC will fail and the VM network will not come up. So be sure
To ensure VMs will deploy correctly with a working network, erase all trace of physical addresses in the network scripts.
Virtual disk file formats
Compressed format
VM Templates can be very large and flat formats can have a size equal to the total virtual disk capacity. To minimize download overhead when distributing a VM template, convert it to a compressed format like VMDK-streamOptimized or QCOW2-compressedSparse.
