[libvirt] qemudDomainSetMemory() / qemudDomainSetVcpus() error codes

Hello, I noticed qemudDomainSetMemory() / qemudDomainSetVcpus() use the VIR_ERR_INTERNAL_ERROR error code when the caller attempts to set the mem/vcpus of an active domain. In this case, returning something like VIR_ERR_NO_SUPPORT would indicate that this is an invalid call - which would distinguish the error from a failure that occurred during the call. Is it possible to use such a return code to indicate what is supported by QEMU/KVM and what isn't? Thanks! -- Kaitlin Rupert IBM Linux Technology Center kaitlin(a)linux.vnet.ibm.com
