Ah, the dynamic linker is picking up an old version of libxenstore.
xs_suspend_evctnn_port was introduced in Xen 3.4.0. I missed that in your
log-file snippet.
Oh, ok, should it be in /usr/lib then or how to fix it ?
It should be where your dynamic linker will find it. :-)

One more thing, should the xenstore daemon be running or not? Isn't it in kernel and xenfs now ? I saw there's a file:

/usr/src/redhat/BUILD/kernel-2.6.32.15/drivers/xen/xenfs/xenstored.c

in the kernel source codes. But I'm still having /usr/sbin/xenstored. Should this be running or not?

Also, when I kill it there's an error:

Did xenstore location change or something?

# ls -al /usr/sbin/xenstored
