[SOLVED] KVM not available yet dmesg says it is and so does BIOS setting, both VM's and CT's don't run

[obs-1337]

getting TASK ERROR: KVM virtualisation configured, but not available. Either disable in VM configuration or enable in BIOS.
when I start a VM, however KVM is enabled in BIOS

attempting to update firmware but HP gives me a RPM file for i386 so that's not very helpful
EDIT: firmware updated but still no change. this is on a fresh install

EDIT: Additionally, turning KVM off results in this error:

hi,

dmesg | grep DMAR

this isn't for KVM, DMAR is DMA remapping for IOMMU. you should enable "VT-x" in your BIOS in order to activate KVM

when I start a VM, however KVM is enabled in BIOS

what do you get from lsmod | grep kvm
if you don't see output here, then KVM isn't enabled.

containers also don't work

containers should work irrelevant of KVM.
what is your pveversion -v output and the configuration for that container: pct config 101

No output from lsmod | grep kvm.

Virtualization and VT-d are enabled. Is VT-x different?

https://ark.intel.com/content/www/u...0-20m-cache-2-60-ghz-8-00-gt-s-intel-qpi.html
according to the spec sheet my hardware supports VT-x, (diffrrent than VT-d), but I can't seem to find where to enable it

VT-x would be the same as "Intel Virtualization Technology". it seems enabled from your screenshot, but if you're not getting any output from grepping kvm in lsmod, then the kernel module isn't loaded.

proxmox-ve: 7.0-2 (running kernel: 5.4.73-1-pve) pve-manager: 7.0-11 (running version: 7.0-11/63d82f4e) pve-kernel-5.11: 7.0-7 pve-kernel-helper: 7.0-7 pve-kernel-5.11.22-4-pve: 5.11.22-8

you seem to be running the older 5.4 kernel while the 5.11 is installed. how was the installation made? if you installed using our latest ISO you should have the 5.11 kernel by default. did you install the older kernel?
please try booting with the 5.11 kernel version and see if the problem occurs.

yeah this is a fresh install from 7.0. I don't remember there being a kernel version setting in the installer, I'll try reinstalling again

Seems to be working fine now with a fresh install onto wiped disks, I think some old LVM's messed up the installer
