Hello,

I've been trying = to make a stable XEN virtualization system with FreeBSD as Dom0. The proble= m is that at some point system panics (normal, non-stressful use-case), i h= ave somehow found scripts and setups with witch i can provoke panic sooner.=

I have reported bug at https://bugs.freebsd.org/bugzi= lla/show_bug.cgi?id=3D261059 with as detailed info as i could gather, i= ncluding some of panic stack backtraces.

In sh= ort - is anyone using ZFS + XEN + FreeBSD as Dom0 as a stable system? Can s= omeone share his configuration or ideas, so i can try out? I've been ex= perimenting with iSCSI as well, but it seems that at some setups the disk s= peed is really slow, and sometimes system panics as well, so i was going fo= r the simplest setup.

Other question, what could i= do to help to solve the issues i have found in bug=20 261059? More verbosity flags, some other debugging files, locations?
