I recently installed xen-2.0.7 and, after playing a bit with LVM2 I cant start xend anymore. "xend start" gives:

Exception in thread Watcher:
Traceback (most recent call last):
  File "/usr/lib/python2.3/threading.py", line 436, in __bootstrap
  File "/usr/lib/python2.3/threading.py", line 416, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/usr/lib/python/xen/xend/xenstore/xswatch.py", line 45, in watchMain
    cls.xs = xs.open()
RuntimeError: (111, 'Connection refused')

a quick look at /usr/sbin/xend suggested me to start xenstored separately and:

mprotect(0x43084000, 4096, PROT_READ)   = 0
mprotect(0x13c000, 4096, PROT_READ)     = 0
munmap(0xb7ffa000, 21181)               = 0
fork(FATAL: Failed to bind to domain exception virq port: Function not implemented
)                                  = 4009
--- SIGCHLD (Child exited) @ 0 (0) ---
exit_group(0)                           = ?

it seems like kernel lacks xen capabilities, but:

# dmesg | grep -i xen
Linux version (root@sixtyfour) (gcc version 3.4.3 20050227 (Red Hat 3.4.3-22.1)) #1 Thu Oct 6 02:28:03 CEST 2005
 Xen: 0000000000000000 - 0000000020000000 (usable)

PCI: Using configuration type Xen
xen_mem: Initialising balloon driver.
IA-32 Microcode Update Driver: v1.14-xen <tigran@xxxxxxxxxxx>
Xen virtual console successfully installed as ttyS

what's going on?

thanks in andvance,
