--000000000000488e1f060ed6bffe Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Warner Losh,did you read the messages that I tried to send you ? You never replied to one of my messages privately. He mentioned xen and there is some work to do even in this area,trying to fix the missing code on FreeBSD for arm 32 and arm 64 bit because FreeBSD as domU does not boot when virtualized with xen. I've been working on this for several months. You helped me,but not so much,probably because you don't care so much about xen for FreeBSD ? Instead,I care. I think FreeBSD needs that xen works great there. Unfortunately now I'm definitely stuck at some points. I need professional help to make progress. You can be the right person,but you seem not interested. On Sat, Jan 13, 2024 at 5:53=E2=80=AFPM Warner Losh <imp@bsdimp.com> wrote: > Hi Sairaj, > > Thanks for your interest in the FreeBSD project.
