[Pkg-libvirt-maintainers] Bug#700445: libvirt has an wrong/inconsistend view on cpus

[Philipp Schmidt]

Package: libvirt-bin
Version: 0.9.12-6~bpo60+1
Severity: important

KVM-Hosts only use the first 6 of the available 12 cores on my machine 
(HP ProLiant DL385 G7), but i can use taskset to manually pin the qemu-kvm 
to the remaining cores.
