I have three Rhel5.1 x86_64 xenhosts with different 32 bits domU, centos 5.1, centos 5.0 and rhel5.1 included ... I think that problem is selinux. In redhat docs explains that domU needs to reside on /var/lib/xen if you use selinux. You can try to disable selinux (/etc/sysconfig/selinux) and all works ok. -- CL Martinez carlopmart {at} gmail {d0t} com
