Description of problem: When try to get vcpus info using libvirt-tck,hash can't have keys mentioned in man page(cpu,cpuTime,state) Version-Release number of selected component (if applicable): libvirt-0.10.2-17.el6.x86_64 perl-Sys-Virt-0.10.2-5.el6.x86_64 kernel-2.6.32-348.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.348.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.in libvirt-tck script,added ..... my @vcpuinfo = $dom->get_vcpu_info(); foreach my $info(@vcpuinfo){ while ((my $key, my $value) = each %$info){ diag "$key => $value\n"; } } ..... Actual results: only list below two keys and values for each vcpu, i set vcpus to 3 # number => 0 # affinity => # number => 1 # affinity => # number => 2 # affinity => Expected results: per /usr/share/man/man3/Sys::Virt:domain.3pm.gz, get_vcpu_info should have 'number,cpu,cpuTime,state,affinity' Additional info: using virsh cmd line,result as below: # virsh vcpuinfo win2012 VCPU: 0 CPU: 2 State: running CPU time: 22780.5s CPU Affinity: yyyy VCPU: 1 CPU: 0 State: running CPU Affinity: yyyy VCPU: 2 CPU: 0 State: running CPU Affinity: yyyy
commit f8514d9440ccc6827d6cb7d71e891fae10a26ad1 Author: Daniel P. Berrange <berrange@redhat.com> Date: Tue Aug 6 15:46:02 2013 +0100 Fix handling of flags in get_vcpu_info() We must always use virDomainGetVcpus if flags is zero and fall back to virDomainGetVcpuPinInfo if we get an error indicating the guest was shutoff.
verify with build perl-Sys-Virt-0.10.2-6.el6.x86_64 step: 1: prepare a guest with 3 vcpus 2: write a script to print vcpu info .... my @vcpuinfo = $dom->get_vcpu_info(); foreach my $info (@vcpuinfo){ print " VCPU: {\n"; foreach (sort { $a cmp $b } keys %{$info}) { if ($_ eq "affinity") { print " ", $_, ": "; my @mask = split //, $info->{$_}; for (my $p = 0 ; $p < $nodeinfo->{cpus} ; $p++) { print ((ord($mask[$p/8]) & (1 << ($p % 8))) ? 1 : 0); } print "\n"; } else { print " ", $_, ": ", $info->{$_}, "\n"; } } } .... get result: VCPU: { affinity: 1111 cpu: 0 cpuTime: 40000000 number: 0 state: 1 VCPU: { affinity: 1111 cpu: 2 cpuTime: 0 number: 1 state: 1 VCPU: { affinity: 1111 cpu: 1 cpuTime: 0 number: 2 state: 1 move to verified.
