 Hello guys,

 I installed FreeBSD 9.1 (64 bit) in XenServer (5.6.0)! It's running
 perfectly, following the tutorial below:

 http://www.vanhal-ict.nl/1/post/2012/8/freebsd-9-domu-on-xen-part-i-installing-freebsd.html

 But the moment you recompile the kernel GENERIC, the system hangs on load. 
 Even
 making the changes suggested in the tutorial (Part II: Optimizing FreeBSD) or
 not.

 The system does not load! as follows my print:

 http://200.189.101.110/~edm/FreeBSD-Xen-Stop.png

 Reloading the old kernel, the system up! Does anyone have any idea what could
 be the problem?

 Best regards,


Also, I would check if multiuser output is properly routed.  Check your
/etc/ttys. I don't remember well but to get them you probably need to
replace ttyv0 with xc0 which is the default Xen console instead of UART.

That would answer why you see kernel messages and don't see multiuser ones
which usually appear right after cd0 string or close to.

  I've just been able to install it on a VPS using the latest pvhvm_v9
 branch.

 The branch pvhvm_v9 contains an initial implementation of PV IPIs for
 amd64. I've now finished it and I'm going to port it to i386 also, and
 push a new branch to the repository.

  This is good news, because the system I had before actually had trouble
 with the HVM kernel from 9.1 [0].
 
  I'm going to leave this running for a while and do some more tests on it.

 I built the rev_9 branch on a XCP host and rebooted, however I am seeing

Can you recheck this on stock HEAD?

From your description this looks like a rather old bug seen with 8.2
or above and XCP (referenced in PR kern/164630). You can trigger it
when e.g. booting with empty cdrom.

 You may try to apply the patch from svn r225708 and see if it helps,
 or just jump to 9.0:
