Is VIR_DOMAIN_VCPU_MAXIMUM really applicable here? The docs should probably mention that it is a subset of virDomainVcpuFlags.

We've missed the 0.9.0 feature freeze, can you adjust this patch series to be for 0.9.1? -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
