[Xen-devel] xen debugger ??

Hurdle race continues ..


xm create now fails silently ....

xen412:/etc/xen# xm create -c freebsd_xen
Using config file "./freebsd_xen".
Started domain freebsd-xen


Note: no errror msg :(


From xend.log ... all that I see is domain has crashed ..

I tried xm dmesg which dumps kernel stack ....


Can I somehow get a stack-trace for this crash ? And all this boils down to if there are ways to increase the verbosity of xend.log or dmesg ...
Or if there are better ways to debug it ?

Looking forward to hear from you fellas ...
