Hi all, This patchset improves virsh vcpupin command like the following: (i) introduce special markup "-" and "^" which are similar to XML schema of "cpuset" attribute # virsh vcpupin VM 0 0-8,^4 --config # virsh dumpxml VM ... <vcpu>4</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0-3,5-8'/> </cputune> ... (ii) allow to receive the special keyword 'r' as a cpulist parameter when resetting vcpupin setting. # virsh vcpupin VM 0 r --config (iii) when resetting, that is, pinning the specified virtual cpu to all host physical cpus, vcpupin setting will be deleted # virsh dumpxml VM ... <vcpu>4</vcpu> <cputune> </cputune> ... The following my patchset is the prerequisite of this: http://www.redhat.com/archives/libvir-list/2011-June/msg00390.html *[PATCH 1/4] vcpupin: improve vcpupin definition of virsh vcpupin *[PATCH 2/4] vcpupin: add reset option to virsh vcpupin command *[PATCH 3/4] vcpupin: add virDomainVcpupinDel function *[PATCH 4/4] vcpupin: add vcpupin resetting feature to qemu driver Best regards, Taku Izumi
