Are there any plans to add it? The information is tracked by ovirt, and 
it would be nice to not have to regex scrape the output from 
/proc/cpuinfo :)

Sounds good - which release of libvirt will have all of that, and when?

The link bandwidth is as reported by ethtool - the exotic "SIOCETHTOOL" 
ioctl. A quick snippet:

struct ifreq ifr;
struct ethtool_cmd ecmd;
ecmd.cmd = ETHTOOL_GSET;
ifr.ifr_data = (caddr_t)&ecmd;
int ret = ioctl(sock, SIOCETHTOOL,&ifr);

if (ecmd.supported&  SUPPORTED_10000baseT_Full) { ... } etc.
