Re: [libvirt] [PATCH 1/3 V7] add nodeGetCPUmap() for getting available CPU IDs in a cpumap.

Rich: The documentation in libvirt.c correctly says that calling virDomainGetCPUStats(dom, NULL, 0, 0, 0, 0) must tell you part of the information needed to compute the size of an array to allocate; but in v7, the return was off by one too small. But it was generally masked by the v7 virsh code overallocating to a fixed 128 slots rather than paying attention to the return value. I fixed both those problems before pushing the libvirt patches, but since you tested with v7 instead of my fixed version, you may need to double check that virt-top isn't making the same mistakes, as it might be a boundary case that only strikes on machines with 128 physical CPUs. -- Eric Blake eblake(a)redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
