vcpu: support maxvcpu in domain_conf
Although this patch adds a distinction between maximum vcpus and current vcpus in the XML, the values should be identical for all drivers at this point. Only in subsequent per-driver patches will a distinction be made. In general, virDomainGetInfo should prefer the current vcpus. * src/conf/domain_conf.h (_virDomainDef): Adjust vcpus to unsigned short, to match virDomainGetInfo limit. Add maxvcpus member. * src/conf/domain_conf.c (virDomainDefParseXML) (virDomainDefFormat): parse and print out vcpu details. * src/xen/xend_internal.c (xenDaemonParseSxpr) (xenDaemonFormatSxpr): Manage both vcpu numbers, and require them to be equal for now. * src/xen/xm_internal.c (xenXMDomainConfigParse) (xenXMDomainConfigFormat): Likewise. * src/phyp/phyp_driver.c (phypDomainDumpXML): Likewise. * src/openvz/openvz_conf.c (openvzLoadDomains): Likewise. * src/openvz/openvz_driver.c (openvzDomainDefineXML) (openvzDomainCreateXML, openvzDomainSetVcpusInternal): Likewise. * src/vbox/vbox_tmpl.c (vboxDomainDumpXML, vboxDomainDefineXML): Likewise. * src/xenapi/xenapi_driver.c (xenapiDomainDumpXML): Likewise. * src/xenapi/xenapi_utils.c (createVMRecordFromXml): Likewise. * src/esx/esx_vmx.c (esxVMX_ParseConfig, esxVMX_FormatConfig): Likewise. * src/qemu/qemu_conf.c (qemuBuildSmpArgStr) (qemuParseCommandLineSmp, qemuParseCommandLine): Likewise. * src/qemu/qemu_driver.c (qemudDomainHotplugVcpus): Likewise. * src/opennebula/one_conf.c (xmlOneTemplate): Likewise.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
