if you speak of debugging , uml seems to have another competitor now. maybe somebody make some side by side comparison of vmware & uml regarding kernel debugging. (and also compare that to traditional debugging via serial line or network) regards roland > -----Ursprüngliche Nachricht----- > Von: albcamus <[EMAIL PROTECTED]> > Gesendet: 20.04.07 09:16:53 > An: roland <[EMAIL PROTECTED]> > CC: linux-kernel@vger.kernel.org > Betreff: RE: VMWare Workstation 6 for debugging Linux Kernel (!) > > Hi roland, > It's really an interesting feature, IMHO, maybe the UML would be no > more needed. > thanks very much;-) > > Regards, > > > 2007/4/20, roland <[EMAIL PROTECTED]>: > > Hi ! > > > > I think this one is damn interestig for linux kernel development: > > > > link: http://stackframe.blogspot.com/ > > contents: see below > > > > regards > > roland > > > > ps: > > i`m not directly related to vmware - so this is no advertisement! > > > > > > Tuesday, April 17, 2007 > > Debugging Linux kernels with Workstation 6.0 > > We just quietly added an exciting feature to Workstation 6.0.
