Not surprisingly one or two problems have cropped up. So here's a short series of patches to fix the problems I've found. virConnectGetMaxVcpus has a second "type" parameter. In practice this isn't used and can be passed as NULL. However that fails in the remote case. The fix is simple enough -- attached.
