Hi,
we are running an Openstack Newton based research cloud using Ubuntu
16.04 on the hypervisor, with qemu 2.5 as hypervisor in kvm mode
(package 2.5+dfsg-5ubuntu10.16).
VMs are running fine with less or equal 1 TB RAM. More RAM results in a
kernel panic during VM boot:

[ 30.101496] Kernel panic - not syncing: Attempted to kill init!
exitcode=0x00000009
This trace is from a stock Ubuntu 16.04 cloud image. Similar traces are also
generated by recent CentOS images or Ubuntu Bionic images.
We have tried so far:
- updating qemu (using 2.10.1 from source, installation in /usr/local/, symlink
of /usr/bin/qemu-system-x86_64, adoption of apparmor)
- updating seabios to version 1.10.2 (package from ubuntu bionic, also replaced
bios image files in local qemu installation in /usr/local/share/qemu)
The stack trace is similar to the one reported in
https://ask.openstack.org/en/question/69258/instances-with-1tb-ram/ , but
unfortunately
there was not solution posted.

(taken from setup with newer qemu, patches to support the machine type
pc-i440fx-xenial requested by openstack)
Disabling kvm (virt_type=qemu in nova.conf) results in the VM being stuck in seabios with
"Booting from hard disk..."
and qemu process consuming 100% cpu.
Any hints how to solve this problem are highly appreciated.
