The problem appears to be related to memory size.
If I run with anything lower than 3.5G then boot is successful but
otherwise isn't. For example, this boots:
# qemu-system-x86_64 -drive
"file=/var/lib/libvirt/images/rump-stressng-x64.qcow2,format=qcow2"
-accel kvm -m 3.4G -serial mon:stdio
Please can others try altering memory size too?
When my system memory exceeds 3.4G the reading of sector 0 for the root
partition returns 512 bytes of zero so parted correctly concludes it
isn't valid. This isn't really much further forward but having a
specific read that is failing should allow me to find the root cause
relatively quickly now. If anyone gets chance to confirm that reducing
the system memory size does allow booting that would be helpful.
Cheers,
Mike.
