ResolutionPlease check version of Virtuozzo installed on server using f.e. this command:
# rpm -q virtuozzo-release
Support for Fedora Core 5 based VEs was added since Virtuozzo 3.0.0-63 version. Prior to this update there was no possibility to run such VEs out-of-the-box since core utilities such as 'cp' in FC5 use /proc filesystem for operation.
Please note that for the changes to take effect you should either restart the 'vz' service after Virtuozzo update is installed or (which does not imply service downtime) issue the following command on the hardware node:
# cat /proc/sys/kernel/virt_osrelease | sed "s,2\.6\.8,2.6.9,g" > /proc/sys/kernel/virt_osrelease
