Re: [Xen-users] xend won't start on Ubuntu Hardy server

I'm still concerned about the earlier error, though.  The (apparent)
fact that no one can explain it makes me worry that it might pop up
again with no warning.  I'd welcome any thoughts.

I've also seen the message
ImportError: /usr/lib/python2.5/site-packages/xen/lowlevel/xc.so:
undefined symbol: xc_domain_setcpuweight

AFAICT the culprit was the hardy-backports repository providing a 3.3
version of libxen3. This seems to be exceptionally brain-dead since it
is the only available Xen-related package that is on 3.3 level. All
other Hardy Xen packages (xen-utils, the hypervisor etc.) are still 3.2.
After replacing the libxen3 from backports with the 3.2-version from
main, I was able to start xend again.
I got a running 3.3 system from Hardy backports with 3.3 packages of xen-utils, hypervisor and python-xen. My problem and solution was to uninstall xen-utils 3.2 before installing 3.3.
