Since AOS 5.5 the Self Service Portal and therefore the image management has moved to Prism Central.
When you want to register a disk image from a VM from one of your AHV clusters to Prism Central you have to use the NFS path to the image.
For example:
nfs://<clusterip>/container_1/.acropolis/vmdisk/01c96451-1e72-4f0d-a8f5-d15ed90227a4
how to get the image path from my VM image?
in this case I want to get the image path from the VM with the name Centos_Base_Image
therefore I have to connect to any CVM in the cluster and use an acli command:
:~$ acli vm.get Centos_Base_Image include_vmdisk_paths=true
Centos_Base_Image {
config {
agent_vm: False
allow_live_migrate: True
disk_list {
addr {
bus: “ide”
index: 0
}
cdrom: True
device_uuid: “9691bb69-3051-4981-b94a-edb05ce098a9”
empty: True
}
disk_list {
addr {
bus: “scsi”
index: 0
}
container_id: 1277
container_uuid: “8a2b6760-d08e-44d9-bafb-7451fb186d04”
device_uuid: “0fb03dcd-3c35-4c61-8741-8e9e91e58259”
vmdisk_nfs_path: “/container_1/.acropolis/vmdisk/01c96451-1e72-4f0d-a8f5-d15ed90227a4”
vmdisk_size: 8589934592
vmdisk_uuid: “01c96451-1e72-4f0d-a8f5-d15ed90227a4”
}
and here it is: /container_1/.acropolis/vmdisk/01c96451-1e72-4f0d-a8f5-d15ed90227a4
now just add “nfs://<clusterip>” before and you got it.
To make my life easier I wrote some lines of bash code to generate the image path:
imgname='Centos_Base_Image'
clusterip=`ncli cluster get-params | grep 'External IP Address' | awk '{print $5}'`
nfspath=`acli vm.get $imgname include_vmdisk_paths=true | grep nfs_path | awk '{print $2}' | sed 's/"//g'`
echo 'nfs://'$clusterip'/'$nfspath
Example:
nutanix@NTNX–C-CVM:10.x.y.71:~$ imgname=’Centos_Base_Image’
nutanix@NTNX–C-CVM:10.x.y.71:~$ clusterip=`ncli cluster get-params | grep ‘External IP Address’ | awk ‘{print $5}’`
nutanix@NTNX–C-CVM:10.x.y.71:~$ nfspath=`acli vm.get $imgname include_vmdisk_paths=true | grep nfs_path | awk ‘{print $2}’ | sed ‘s/”//g’`
nutanix@NTNX–C-CVM:10.x.y.71:~$ echo ‘nfs://’$clusterip’/’$nfspath
nfs://10.11.11.60//container_1/.acropolis/vmdisk/01c96451-1e72-4f0d-a8f5-d15ed90227a4
Now I can add the image in Prism Central using the URL:
I’m pretty sure that we will see some improvements for this process in one of the upcoming releases.
