Hi Dave,
the xapi-xe-0.2-5669.i686 RPM came from the XenServer 6.2 Install
ISO-Image and I'm currently wondering where I could get the xe
debug-info RPM. Previous used xapi-xe-RPM's came from the XCP ISO Image.
Without debug-info, it looks like this in gdb (not useful):
I see what you mean!
Although I'm still curious to understand this failure, you might have
better luck with a version of xe which I've compiled specifically for
CentOS 6.4 x86_64:
http://xenbits.xen.org/djs/xenserver-tech-preview.20130707.1/RPMS/x86_64/xapi-xe-1.9.16-0.x86_64.rpm
Let me know if that one works better for you.
Cheers,
Dave

Hello,
I get a Segmentation fault with the 'xe' command (RPM
xapi-xe-0.2-5669.i686 and earlier versions) if I use the '--nossl'
parameter on a CentOS 6.4 (64bit) server. Without the '--nossl'
parameter 'xe' works fine. We are using LDAP with 'sssd' for
authentication and if we fall back to 'nscd' the Segmentation fault
doesn't occur. That would be our workaround for now.
FYI, I couldn't reproduce this on Ubuntu with a 64-bit build of xe (from
the xcp-xe package). I'll see about reproing this on CentOS 6.4.
[root@lizard2 bin]# xe vm-list -s xenbase01 -pwf pwfile.xenbase01
--nossl
Segmentation fault
Can you find and install the xe debug-info RPM? If so then you could
enable core dumping
ulimit -c unlimited
then perform another repro, which will make a core dump file
("core.PID"). If you install gdb
yum install gdb
you can then get a backtrace from it using
gdb xe corefilename
and typing in "bt" (for "backtrace"). That would be very interesting!
Cheers,
Dave

We want to replace our current administration server (RHEL
5.9/LDAP/nscd) with a newer one (CentOS 6.4/LDAP/sssd). Our XEN pools
are running with XenServer 6.2 (just updated).
Had anybody else a similar problem with 'xe' ?
