[CentOS-virt] Loading default keymap error after a yum update...

Hi, I'm running CentOS 5.3 on a XEN VPS.

After I yum update, I've got this error on boot.

Press 'I' to enter interactive startup. Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. Setting clock (utc): Thu Jul 16 18:54:50 CEST 2009 [ OK ] Starting udev: [ OK ] Loading default keymap (us): /etc/rc.d/rc.sysinit: line 396: /dev/tty0: No such file or directory [FAILED] Setting hostname localhost.localdomain: [ OK ]

is there a solution to that problem? please help. thanks. Davide.
