Patches for RHEL 5.6 posted: http://post-office.corp.redhat.com/archives/rhvirt-patches/2010-October/msg00178.html Note that this is a bare minimum subset of what is going upstream in 0.8.5 - rather than backport the new convenience APIs of virDomainSetVcpusFlags, you have to do raw XML editing. But it is sufficient to provide the desired feature. *** Bug 644159 has been marked as a duplicate of this bug. *** Verified PASSED on 4 arches(RHEL5u6-Server-ia64-Xen,RHEL5u6-Server-x86_64-Xen,RHEL5u6-Server-x86_64-Kvm,RHEL5u6-Client-i386-Xen) with build: libvirt-0.8.2-7.el5 kernel-2.6.18-228.el5 kernel-xen-2.6.18-228.el5 xen-3.0.3-117.el5.
