[Fedora-xen] xm save/migrate doesn't work

[George]

Hi,

I tried to use the "xm save" and "xm migrate" feature of Xen on FC5
(all updates installed, kernel is 2.6.16-1.2080_FC5xen0) but a "xm
save" fails with the message (from the xend.log):

--------------------------
[2006-04-16 20:39:12 xend] DEBUG (XendCheckpoint:79) [xc_save]:

Traceback (most recent call last):

    raise XendError("%s failed" % string.join(cmd))
XendError: /usr/lib64/xen/bin/xc_save 10 17 27 0 0 0 failed
--------------------------

The same problem exists with "xm migrate" because it calls a "xm
save". It looks like this problem is releated to FC5 and Xen because
on other (non FC5) platforms it works.

Are there any workarounds for this problem?
