I am new here, please warn me If I am not following proper etiquette of this mailing list.

I am breaking my head, regarding why libvirt is defining multiple CPU sockets when I increase the vCPU count. As and when I increase the vCPU count in libvirt guest XML, it is increasing the CPU sockets in qemu instance.

" -smp 4,sockets=4,cores=1,threads=1 " instead " -smp 4,sockets=1,cores=4,threads=1" 

Does not this lower the performance of the guest as the host and guest architectures gets different in that case.

Also please suggest a guest configuration which will take advantage of the host CPU architecture.

Your help will be highly appreciated.
