Public bug reported:
When building the test environment for subiquity I end up with an image I can
run with qemu/kvm.
And I realized that this works fine with the Trusty kernel (Host), but when
running on trusty+hwe-t (4.2.0-23-generic) it reliably crashes my host (not
only the guest).
On the good side it seems
1. 1005 reproducible
2. always the same issue
The Commandline I run is:
sudo qemu-system-x86_64 -smp 2 -m 1024 -enable-kvm -bios
/usr/share/ovmf/OVMF.fd -drive
snapshot=on,format=raw,cache=unsafe,if=ide,file=ubuntu-server-daily-wily-amd64-installer.img,serial=QM_INSTALL_01
-drive format=raw,cache=unsafe,if=ide,file=target.img_1,serial=QM_TARGET_01
-drive format=raw,cache=unsafe,if=virtio,file=target.img_2,serial=QM_TARGET_02
-drive format=raw,cache=unsafe,if=virtio,file=target.img_3,serial=QM_TARGET_03
-drive format=raw,cache=unsafe,if=virtio,file=target.img_4,serial=QM_TARGET_04
-global isa-fdc.driveA= -net user -net nic,model=e1000 -net nic,model=virtio
-net nic,model=i82559er -monitor telnet:127.0.0.1:2446,server,nowait -serial
stdio
I'll attach what I've seen in dmesg, let me know if you need any more
debug data.
If one provides me a upload target I can share the image I boot (2GB).
