Install OpenManage Entreprise (OME) on Proxmox

Just like the people who have a Homelab, I'm scared about losing servers / datas and not having the information of a futur potential disaster.

So I installed OME (OpenManage Entreprise) to monitor all of my Dell servers. I choose OME because I want something that I could use in my professional life.
The first problem is that Dell didn't provide an image for Proxmox.

We're looking for the OVF format

Uncompress & convert

We need to install unzip on Proxmox

apt-get install unzip
unzip openmanage_enterprise_ovf_format_3.1_X02.zip\?uid\=3643957f-581f-42c6-283d-3dc20245b4f7\&fn\=openmanage_enterprise_ovf_format_3.1_X02.zip

2 files are interesting to us
putty_2019-01-08_13-21-02-2
The OVF file told us lot of informations, the VMDK used to deploy the VM and the populatedSize of the VMDK disk

VMDK to QCOW2

The qemu-img command is pre-installed on Proxmox, and can be used to convert (with the convert option) the "disk image filename" to another disk image format.

putty_2019-01-08_18-13-29

And here's most used format supported by the convert option

Image format Argument
QCOW2 (KVM, Xen) qcow2
VMDK (VMware) vmdk
VHD (Hyper-V) vhd
raw raw
VDI (VirtualBox) vdi
QED (KVM) qed

We have a VMDK used in VMware product (ESXI for exemple), we can convert it to qcow2

qemu-img convert -f vmdk openmanage_enterprise.x86_64-0.0.1-disk1.vmdk -O qcow2 OpenManageEntreprise-3-1.qcow2

Result of the command

Web interface - Proxmox, VM creation

I don't know why, but you cannot import a hard disk in the Proxmox VM creation, so we're gonna create a "fake one".

Create a new VM (a normal VM in many ways)

Chose a name

Do not use media for OS installation

Create a 2 GB qcow2 disk
firefox_2019-01-08_18-35-59
2 KVM cores
firefox_2019-01-08_18-36-13
3072 GB of RAM, 4 would be better but I don't have so much RAM on my Proxmox
firefox_2019-01-08_18-36-28
If you can't create a qcow2 hard disk it's because you need to enable the disk image content on your storage

Disk replacement

Now, we need to replace the disk created for this VM, first let's see the mounted point of the storage
Point-montage

We did a little tree command and we see our VM with the ID 124
putty_2019-01-10_19-19-06
We replace the disk created by the Proxmox WEB interface by our new converted QCOW2 disk by using a cp command (to conserve a copy of the initiale QCOW2 file) :

cp appliance/vmx/ovf/OpenManageEntreprise-3-1.qcow2 /var/lib/vz/images/124/vm-124-disk-1.qcow2

putty_2019-01-10_19-30-29

Now, we start the VM and ...

The first boot will take a while

OME-BOOT-1
After this, you will need to configure the Appliance
firefox_2019-01-10_19-39-13

It's been ... 10 days, and no complain about OME, it works fine, I just need some more servers to use it at his full potential 😝
