Hi Rajesh, >So, is it a bug that Virt Manager uses more Sockets by default, when i choose “Copy host CPU Configuration” ? Bug, or feature. With a win10 client in a VM, Windows PC Health Check will complain that you do not have enough CPUs to upgrade to win11 if you have (Sockets,Cores,Threads)

thank you very much for reply. I am using master branch. I think I have to configure with --enable-gcov enabled. and then make and make coverage-html works. Thank you for the help. Best, Norman On Wed, May 18, 2022 at 6:27 PM Peter Maydell wrote: > On Wed, 18 May 2022 at 10:14, Jiatong Shen

Hi Peter Thanks. Yes, I believe (Sockets,Cores,Threads) = (1,16,1) should be the best performance, as the VM does not need to access the memory of another NUMA node. So, is it a bug that Virt Manager uses more Sockets by default, when i choose "Copy host CPU Configuration" ? regards, Rajesh
