Related to the mdb code, I'd like to get people's thoughts on something. With these changes plus an upcoming S10 putback, we will be able to debug Solaris 10 HVM domains when they go a bit wonky. Generally, when a change that affects mdb is made, usually that change is made directly in mdb as well, and it's expected to use the correct version of mdb matching the OS version in the dump you're examining. Having said that, a bunch of stuff does still work reasonably well. The nature of xVM means that we're going to be debugging Solaris 10 dumps for a long time to come. Should we be looking at making (and keeping) mdb more robust for older OS versions? Or should we just be backporting mdb_kb to Solaris 10's MDB, and expect services to use the correct S10 MDB version? regards john
