So can Xen change log level dynamically like Linux? If yes, we might change this level temporarily while passing through IGD. If not, any suggestion?First of all you could boot without lowering the log level (non-debug builds) or raising the log level ("loglvl=warning"; debug builds). But
Sorry I don't know how to build "non-debug" here. Could you give me this detail? Or where I can get this info?
that would change the log level for the entire session, which may not be what you're after. I too realized that having a way to dynamically adjust the log level would be useful occasionally. For post-4.6 I have a patch (attached) ready allowing to do so in a limited way from the serial console (and hence also via "xl debug-key").

Good to know this.
Otoh the specific messages you cite are of quite questionable use in the first place. I certainly would welcome a patch lowering their priority to XENLOG_G_DEBUG (which however would still not
