Forti Analyzer VM Setup Proxmox

[chr1zzo]

Hi,

I'm currently trying to deploy a FortiAnalyzer VM (qcow2) on Proxmox VE. The image boots up initially, but I get the following error message during startup:

Image:

FAZ_VM64_KVM-v7.6.3.F-build3492-FORTINET.out.kvm.zip

Setup
Hypervisor: Proxmox VE 7.4-19

VM configuration:

• System disk: faz.qcow2, approx. 4 GB, attached as scsi0

• Second empty disk: 100 GB, attached as scsi1

• SCSI controller: virtio-scsi-pci

• Boot order: scsi0 → no CD → net0

• Network: virtio, VLAN tag 90, bridge vmbr1

• RAM/CPU: 4 GB / 2 cores

Already verified:

• The second disk was present from the very beginning (not added later)

• It's completely empty and correctly attached as scsi1

• scsihw is correctly set to virtio-scsi-pci

• lsblk during boot shows both disks (vda + vdb)

• The VM has been recreated multiple times, using qm destroy --purge and a fresh import

Problem:

Despite the second disk being correctly attached, initialization fails. The system can't mount /var, LVM setup fails, and FortiAnalyzer doesn't fully boot.

Login is not possible (FAZ... login:), but the system is unusable.

Questions:

• Are there any known compatibility issues with Proxmox?

• Could the 100 GB second disk be too small?

• Is there a debug option to get detailed logs of the LVM setup during first boot?

• Does the second disk need to be in a specific format (e.g., RAW instead of QCOW2)?

Any hints or experiences running FortiAnalyzer on Proxmox would be much appreciated.

Best regards,
Christian

Hi Christian

Try increase the RAM to 8GB and try again.

Otherwise, the below guide is for FGT on Proxmox but it may also help for FAZ.

This guide may help as well.

Hi AEK,
thanks a lot for the hint. 
Increasing RAM and CPU did it.
