A new command is included with Technology Level 5 for AIX 7.2 which will allow AIX administrators to create an Open Virtual Appliance (OVA) package. This utility will enable admins to capture a bootable OVA image of their AIX systems rootvg. This OVA package can then either be imported into PowerVC for automated VM deployment or imported into the IBM Cloud for VM deployment with IBM’s Power Virtual Server (PowerVS) capability.
 
According to the full announcement:
 
“AIX adds a new command: create_ova. This new command creates an open virtual appliance (OVA) package. An OVA package is an archive file that can be deployed as a virtual machine. The create_ova command is used to create a single-volume raw disk image and to export contents of a raw disk image to a compatible OVA package format. The OVA package can be imported into any IBM Power Virtualization Center (PowerVC) environment that contains a supported storage device. You can also import the OVA package into any cloud service that supports the Open Virtualization Format (OVF) packaging standard. The imported OVA package can be deployed as a virtual machine.”
 
For more information on the create_ova command, see Figure 1.

Let me walk you through an example and discuss my experience using this new tool.

Creating an OVA Package on AIX 7.2

Once your AIX system has been updated to AIX 7200-05 or higher, you’ll now have access to the new create_ova command (script).
root@aix / # oslevel -s
7200-05-00-0000
root@aix / # which create_ova
/usr/sbin/create_ova
root@aix / # ls -ltr /usr/sbin/create_ova

  ----------------------------------------------------------------------------
  /usr/lib/instl/create_ova                   bos.rte.install       File
root@aix / # create_ova
Usage create_ova: Creates a consummable (single) disk image for PowerVC import activity.
create_ova -o <output directory> [-d <target disk>] [-i <image src file>]
        [-t <os_type>] [-e] [-f]
-o      Specifies output directory for ova asset.
-d      Specifies logical disk target for image restoration/copy.
-i      Specifies an image source file of type: mksysb or raw disk.
-t      Specifies os-type of image source file. Supported types: aix|rhel|sles
-e      Copy volume data of disk target (excludes image restoration).
-f      Ignore filesystem space warnings.
 
The create_ova tool requires the pipe viewer (pv) tool to be installed in order to function. If the tool is not installed, the first time you run create_ova, it will attempt to “yum install” it for you. If you don’t have access to a yum repos (either locally or via the internet), you could grab this tool and install it upfront.
 
“The create_ova command automatically installs the dependent software such as pipe viewer, rpm, and yum before it generates contents of the OVA package without user intervention. If you cannot install or configure any OVA package, you must perform the recovery steps and retry the installation until it is successful.”
 
root@aix / # rpm -qa pv
pv-1.6.6-1.ppc
 
Pay attention to the storage requirements for create_ova, it requires a fair bit of spare storage to perform its work.
 
“Note: When you export the contents of the mksysb image or the contents of a raw disk image, the create_ova command stores the entire content of the volume in the raw disk image. The create_ova command needs enough space to make copies of the volume in the raw disk image and up to 10% extra space for metadata. For example, if the volume in the raw disk image needs 100 GB space, the create_ova command needs an additional 10 GB space (total of 110 GB space). When you use the -f flag, ensure that the output directory on the destination server has enough space for the exported content.”
 
Verify that you meet all of the “Image Requirements,” particularly ensuring that cloud-init is already installed in your existing AIX VM (see Figure 2).

In my testing I chose to try the following example, from the documentation page (seen in Figure 3):

On my test system, I had one spare disk for the alternate rootvg, hdisk2. I had previously created a mksysb image, AIX72-mksysb. The /data file system was setup as a “work space” for the create_ova processes.

For the above to work, I needed a mksysb image in a file system somewhere, a spare disk large enough to clone rootvg and enough free file system space for the image file, the OVA file and free space for the gzip operation i.e. 20GB disk for alt_rootvg, 2-3GB for the mksysb image, approximately 60GB for the image file "work space." For a total of (around) 85GB of storage required for a 20GB image, that compresses down to a little over 1.2GB.
 
During the create_ova process, an image file (.img) is created first. This "raw disk image" appears to be a simple "dd" of a hdisk device to a file i.e. dd if=/dev/hdisk2 bs=1m of=/data/aix_20201007210902.img. Then an ovf (image spec file) is generated and finally the OVA tar archive is built from the .ovf and .img files. Below is an extract of verbose (set -x) output from the create_ova script, showing an example the print_ovf and tar operations.
 
...
+ print_ovf -t aix -n aix_vm -f aix_20201007210902.img -o aix_20201007210902.ovf -c 0
...
+ tar -chvf - ./aix_20201007210902.ovf ./aix_20201007210902.img
 
The resulting OVA package is compressed with gzip.

So, it would be possible to create your own OVF file using the print_ovf utility, if you had a raw disk image already created (i.e. a .img file created with dd).
root@aix /data # /usr/lib/instl/print_ovf

Usage print_ovf: Prints an OVF metafile based on (single) disk asset.


print_ovf -f <file> -o <ovf_name> -t <os_type> [-n <instance_name>]


-f    Specifies filename of raw disk image source.

-o    Specifies output filename for OVF metadata.

-t    Specifies os-type of raw image file. Supported types: aix|rhel|sles

e.g.

root@aix /data # /usr/lib/instl/print_ovf -t aix -n aix_vm -f aix_20201007210902.img -o my.ovf -c 0
 
After the successful creation of my bootable OVA package I could either use this to import into PowerVC or IBM Cloud (PowerVS). Let’s look at each of these examples next.

Importing an AIX OVA Package Into PowerVC

To import the OVA into PowerVC, the very first thing I needed to do was copy the OVA package over to my PowerVC (v1.4.4.1) server. I simply scp’ed the OVA file over.
 
[root@cgpvc ~]# pwd
/root
[root@cgpvc ~]# ls -ltr aix*ova*
-rw-r--r--. 1 root root 1412888271 Oct  6 20:47 aix_20201007210902.ova.gz
 
For easier identification, I renamed the OVA package filename to aix725.ova.gz and then used the “powervc-image” utility to import the OVA image into the PowerVC image library.
 
[root@cgpvc ~]# powervc-image import -p /root/aix725.ova.gz -t 9c774d59-12e0-4c23-9d7f-889c051059d3

The image was imported successfully.
 
You can read more about importing and exporting images with PowerVC here. I recommend you use the “test-conn” option with the powervc-image tool before you attempt to import an image into PowerVC. If the test completes successfully then you should have no issues importing your image. If it fails, then you must resolve the issue(s) before you can import or export an image.

The most important point here is that PowerVC server must have its (own) storage connected via FC (NPIV) (i.e. from the same storage provider that PowerVC is managing). If it is not then the test-conn check will return an error:
 
# powervc-image test-conn --add-zoning 0e880b42-9155-42b9-bd9b-e9ad2f2b67b6
Error: Subcommand only supports Fibre Channel storage and this node has no FC adapters reporting.
Command failed.
 
And, if you attempt to import an image, when the PowerVC server is not connected via FC storage, you’ll see an error similar to this:
[19017] Warning: Fibre Channel provider 'v7k' is not supported because no FC HBA is detected on this node.
 
During the import of the image into PowerVC, I saw the following activity from the PowerVC UI (see Figures 4-9).

Importing an AIX OVA Package Into IBM Cloud PowerVS 

The OVA package I created came from my lab, so, basically, my on-premise AIX server. In order for me to import my (on-premise) AIX OVA package into the IBM Cloud, I first needed to copy the image into the cloud, somehow. To do this, I decided to use the IBM Cloud Object Storage (COS) service. I scp’ed the OVA file over to my Linux jump box, and then used the s3cmd command to upload the OVA file to IBM COS. I renamed the OVA package to aix725.ova.gz before transferring it to COS.
 
cgibson@linux : ~ $ s3cmd put aix725.ova.gz s3://cgbucket/
upload: 'aix_20201007210902.ova.gz' -> 's3://cgbucket/aix725.ova.gz'  [part 1 of 78, 15MB] [1 of 1]

Once the OVA file was uploaded to IBM COS, I followed the steps here, to import the image into my PowerVS “boot image” catalog:
 
$ ibmcloud pi image-import aix725 --image-path s3.eu-de.cloud-object-storage.appdomain.cloud/cgbucket/aix725.ova.gz --os-type aix --access-key xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx --secret-key xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 
The image appeared in my “Boot images” list (see Figure 10).

I was then able to deploy a new Virtual server instance using my new boot image (see Figure 11-12).

Potential and Known Issues

Issue 1: VM fails to boot
After you deploy a VM using your new image (in PowerVC or PowerVS) you may find that the VM fails to boot. You may see an error similar to this (below) on the console:
 
------------------------------------------------------------------------------
                                Welcome to AIX.
                   boot image timestamp: 23:22:06 09/16/2020
                 The current time and date: 23:30:55 09/16/2020
        processor count: 1;  memory size: 4096MB;  kernel size: 45422126
         boot device: /vdevice/v-scsi@30000002/disk@8300000000000000:2
 
007DA000 bytes of free memory remain at address 02026000
 
 
Error: the boot image is corrupted or truncated.
Use alternative media or recovery procedures.
 
EXIT called ok

If you capture AIX debug boot output (boot -s verbose from open firmware or "BOOT_FROM_SEQ -s verbose" on POWER9), you may see the following “dd” error message from the bosboot command:
 
exec(/usr/bin/dd,ibs=1b,obs=64b,of=/dev/hd5){2359760,2425244}
exec(/usr/bin/cat,/tmp/bosboot_2425244_18804/dd.out){2359762,2425244}
dd: write error: No such device or address
65563+1 records in
1024+1 records out
exec(/usr/bin/dspmsg,-s,150,bosboot.cat,48,\n0301-161 %s: dd failed to copy %s.\n,bosboot,bootimage){2359764,2425244}
0301-161 bosboot: dd failed to copy bootimage.
exec(/usr/bin/dspmsg,-s,150,bosboot.cat,100,\n0301-165 %s: WARNING! %s failed - do not attempt to boot device.\n,bosboot,bosboot){2359766,2425244}
 
0301-165 bosboot: WARNING! bosboot failed - do not attempt to boot device.
 
The VM will stop booting at LED code 0c61 (failed to create the boot image). The root cause of this issue is related to a known “behaviour” on AIX and the number of installed devices.pci.xxxx.rte filesets (170+). There are two workarounds available:
 
a) Increase the size of the AIX boot logical volume, hd5, from 1 to 2 PPs
 
or
 
b) Replace the pre-defined AIX chrp boot image with the “bosboot -a -b…” command
 
Note: You may also experience this issue when using this alt_disk_mksysb procedure
 
Issue 2: Error running create_ova script
During testing we uncovered a bug in the create_ova script which prevented the script from working successfully.
 
dd: /data/aix_m308/7/20M02.img: No such file or directory
The aix_m308/7/20M02.img dd resource was not created successfully.
 
If you encounter this error, please edit the create_ova script and change the _STAMP line to the following:
 
_STAMP=$( date +”%Y%m%d%H%M%S”)
 
This issue has been reported to AIX development (Defect SW508362) and a fix is in plan.
