Yes, this is indeed the case. It also explains why I could get TCG
working at all until I added -cpu cortex-a57. Now it is working.
I really think this choice of cpu_model = "cortex-a15" for -M virt is
a poor one. It should always default to something working.
Currently libguestfs has to pass -cpu host when KVM is detected, and
-cpu cortex-a57 otherwise. However we cannot be sure that KVM is 100%
working and that we won't fall back to TCG, which means the -cpu
parameter could be wrong and we would fail to launch the appliance.
Having the correct defaults would prevent this unnecessary failure.
Rich.
