From reading xend code related to changing number of vcpus it appears setting the number of vcpus to a value greater than VCPUs_max is not allowed on a running domain. This restriction is not honored by setVCpuCount() in XendDomainInfo.py. Attached patch makes setVCpuCount() fail if vcpus > VCPUs_max and domain is running. Also, I think the changes should be reflected in managed config of running domain if in fact the domain is managed - so unconditionally call managed_config_save(). BTW, the original code is rather confusing. Essentially the same actions are taken regardless if self.info[''VCPUs_max''] > vcpus, just the order of invocation is changed. But this doesn''t seem to matter since self.info[''VCPUs_live''] is not subsequently used.
