Add an optional parameter (vcpus) to the xc_linux_build function replacing the getenv() previously used and removing the requirement of using maxcpus kernel parameter to limit the number of virtual cpus a guest uses. The value can now be controlled in the domain configuration files. The default value of 1 is set in XenDomainInfo.py but is overridden by parsing the config value.
