Re: [libvirt-users] Passing literal -cpu model string to qemu

On aarch64 with -M virt, the default CPU model is cortex-a15 (a 32 bit CPU). This is IMHO a stupid default, but there we are. Therefore most users will need to pass the `-cpu cortex-a53' or `-cpu cortex-a57' flag to qemu, depending on a complex formula of their host CPU and if they are using TCG or not. However I cannot work out how to pass this through libvirt. The obvious one would be: <cpu><model>cortex-a57</model></cpu> This passes `-cpu host' which is both wrong and likely to be a bug. I tried adding various flags and studying the source, but it's extremely non-obvious how to do this. Also adding the following into cpu_map.xml didn't make any difference:
