Re: [libvirt] Problem setting CPU topology

Hi, I'm trying to set exact CPU topology to qemu-kvm domains to match host's topology. In my case, host topology is: 1 socket, 2 cores and 2 threads. If I set the XML like this: <domain type='kvm'> .. <vcpu placement='static'>4</vcpu> <os> <type arch='i686' machine='pc-0.15'>hvm</type> <boot dev='hd'/> </os> <cpu mode='host-model'> <model fallback='allow'/> <topology sockets='1' cores='2' threads='2'/> </cpu> .. The qemu commandline launched for this domain looks like this: /usr/bin/qemu-kvm -name fedora17-2 -S -M pc-0.15 -cpu core2duo,+lahf_lm,+rdtscp,+aes,+popcnt,+sse4.2,+sse4.1,+pdcm,+xtpr,+cx16,+tm2,+est,+smx,+vmx,+ds_cpl,+dtes64,+pclmuldq,+pbe,+tm,+ht,+ss,+acpi,+ds -enable-kvm -m 1152 -smp 4,sockets=1,cores=2,threads=2 -uuid c573342b-2876-05b8-098e-6d5314cab062 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/home/zeenix/.config/libvirt/qemu/lib/fedora17-2.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -no-kvm-pit-reinjection -no-shutdown -no-acpi
