When generating TC rules for domain's outbound traffic, Libvirt will use the 'average' as the default for 'burst' - it's been this way since the feature introduction in v0.9.4-rc1~22. The reason is that 'average' considers 'burst' for policing. However, when parsing its command line TC uses an unsigned int (with overflow detection) to store the 'burst' size. This means, that the upper limit for the value is UINT_MAX, well UINT_MAX / 1024 because we are putting the value in KiB onto the command line.
