Comment 23 for bug 1866870

This particular command seems to hang on:

qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5]
qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]

I tried to execute (thinking I was in a shell):

{"execute":"qmp_capabilities"}
{"execute":"query-cpu-definitions"}

I might have misinterpreted what you wanted me to do.
