Xen devel - Sep 2004 - xen-2.0 20040920 and 20040917 problems

Hello

xen-2.0 20040920:
''xm create -F xxx.sxp'' gives ''Error: Internal Server
Error'' with today''s
build, with configurations that have previously worked ok. What 
information would be useful, have others encountered this? I have 
sometimes had this error before, but it went away if I stopped xend and 
then restarted it (I was surprised and pleased that I could do this 
without having to restart xenU domains that were already running).

xen-2.0 20040917:
This build has been running quite successfully. BUT there remains a 
problem with page/block handling (I think). The situation is

NOT OK: rpm operations in xenU guest system:
Almost any operations on the rpm database produce a floating point 
exception. Sometimes not at first, but once it happens the situation is 
not recoverable - that xenU guest system has no usable rpm database. 
Rebooting (xenU only and xenU as well) does not change the situation.

OK: rpm operations chrooted into xenU file system from xen0:
The same operations that fail in the xenU guest system work ok on the 
same data in the chrooted environment. The sequence is: start xenU 
domain, login, ''rpm -qa'' -> BANG; shutdown, chroot into
xenU root
filesystem, ''rpm -qa'' -> correct behaviour.

I tried using nfs and loop device root filesystems with similar results. 
Curiously the previous problem I encountered and reported here also 
manifested itself in the first place as a floating point exception 
triggered by operations on the rpm database. But that affected Xen0, 
while this problem seems only to affect xenU.

I have not noticed any oddities in the xen0 environment.

The system was compiled using gcc3.4 - I don''t know whether that has 
been found significant. Has anyone else encountered similar problems?

The xensv web interface now works fine - but I haven''t yet used the 
domain creation wizard.

Thanks for your help
Peri

I''ve fixed this one. The daemonization patch I applied over the
weekend didn''t properly redirect stdin/stdout/stderr. I do that now,
although for some reason I don''t capture output from C extensions that
use printf/fprintf -- the output for those seems to get /dev/null''ed,
even in a debug build of xend.
