Hi all,
I've tested several versions of Xen (2.0, 2.0.3, 2.0-testing, unstable)
on different machines (VIA C3, PIII, AMD XP), all running up-to-date
gentoo system and I'm unable to migrate (or even save) domains on any of
those machines.
Currently I'm making tests mainly on the Athlon box, on which I've tried
two GCC versions - 3.3.5 at first, later I've recompiled glibc and then
Xen 2.0.3 with gcc 3.4.2; still no luck.
xend is running, xfrd is running, all requirements are installed
(twisted 1.3, ip, brctl), virt-1 domain is running against local 'file'
based VBDs.
# xm dmesg | grep version
Xen version 2.0.3 (root@here) (gcc version 3.4.2 (Gentoo Linux 3.4.2-r2,
ssp-3.4.1-1, pie-8.7.6.5
)) Tue Jan 18 21:14:17 CET 2005

# xm migrate virt-1 localhost

Logs for the 'save' attempt are attached. Any hints?
TIA
