Backup and restore ovzdump error

Hi all,

first, happy new year all.

I have a problem, if i backup a vm of openvz with command: vzdump --suspend 4163 and i upload it on proxmox server and start restore with command: vzrestore filename.tar 103

i get in console following errors:
- udev requires hotplug support, not startet... failed
- fast boot enabled... warning
- startpar: service(s) returned failture: udev... failed

And the restored vm does start very very slow.
What can i do to fix this errors and to start vm in normal speed? Please help. Thery thanks.

regards
