kvm monterey/ventura hang during install

[F1 Outsourcing Development]

I am trying to install monterey/ventura. But looks like in both the install hangs around where the progress bar is in the middle under the apple logo (with black background)

Any idea how I can debug this?

Proxmox 8 on AMD CPU

This did the the trick:

echo 1 > /sys/module/kvm/parameters/ignore_msrs
# echo "options kvm ignore_msrs=Y" >> /etc/modprobe.d/kvm.conf && update-initramfs -k all -u
echo "options kvm ignore_msrs=Y report_ignored_msrs=0" > /etc/modprobe.d/kvm.conf
echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" > /etc/modprobe.d/iommu_unsafe_interrupts.conf
update-initramfs -k all -u
