PVE 8.2 Installer Failing - Need Assistance

[BlackoreanGG]

Hey All,

I'm fairly familiar with Proxmox, but this is a first for me.
I'm trying to install PVE 8.2 on a Dell PowerEdge R710 that I just reset and nuked the drives to start over with a blank canvas.
I've enabled both the embedded Gig NIC and PCIe GIg NIC, Flashed the BIOS to the 6.6.0 (latest).
I've made sure that my VLANs are accessible to my DHCP server.

I'm able to boot to the USB hosting the installer and initiate the PVE Automated Installer, then I'm thrown this error:

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
done
Starting chrony for opportunistic time-sync...
Starting a root shell on tty3.
[ 78.148555] DMAR: ERROR: DMA PTE for vPFN 0xcf4de already set (to cf4de003 not 1137ab003)

/sbin/unconfigured.sh: line 236: 2266 Bus error /usr/bin/proxmox-low-level-installer dump-env

Where should I start looking to begin troubleshooting?

-Thanks

You could temporarily disable Intel VT-d within the BIOS for the installation process.

I'll give it a try. Any idea why having virtualization enabled would cause the installer to abort?

Were you ever able to fix this issue?

Did you solve it? I have the same problem, I have already installed it on 3 DELL servers and this R710 is like this. Disabling, after installing, do I enable it again? Won't you have problems with VT-d disabled?
