[Qemu-devel] Hyperthreading in the VM host

[Julian Chesterfield]

Hello, I'm still familiarising myself with the Qemu application and code, 
so apologies if this query has already been addressed or is 
inappropriate here! 

My understanding is that Qemu does not support hyperthreading in the host 
OS. I'm wondering what the arguments are for and against such support. Is it 
in fact architecturally feasible and could there potentially be any performance 
gain?

Thanks!
Julian
