Hi there,

i need some help with my Dell OptiPlex Micro Cluster.

I wanted to build up a four node cluster but everytime i try to install the Nutanix CE, right at the finish line it says:

“Waiting for the Nutanix Controller VM to start up………...…”
followed by:

“A Problem was encountered. Please review the contents of /home/install/firstboot.out for details, and refer to the documentation or the Nutanix NEXT community for next steps. Press <Enter> to return to the login prompt.”

Now if i restart the installation and try to repair the CVM this error appears:

FATAL: AN exception was raised: Traceback (most recent call last):
File “./phoenix”, line 96, in <module>
File “./phoenix”, line 74, in main

params = gui.get_params(gui.CEBootDiskConfirm)

File “./phoenix/”, line 1675, in get_params

if guitype(args=args).skip_get_params: 

File “./phoenix/”, line 687, in __init__

self.boot_disk = self.get_ce_boot_disk()

File “./phoenix/”, line 772, in get_ce_boot_disk

for disk in [disk for disk in usable_disks if “nvme” in disk]:

TypeError: argument of type ‘DevInfo’ is not iterable

my Specs:

Dell Optiplex Micro 7070

i5-9400T (6core)

32 GB, 2 x 16 GB DDR4 2.666 MHz

M.2 256 GB PCIe NVMe Class 35

Additional 2.5 inch 1TB 7200rpm Hard Disk Drive


SanDisk Extreme Pro 128 GB as boot device


I prepared the boot stick with rufus 3.8


Whats the problem with this configuration?

Already found the problem.

NVMe-based drives are not supported.
