[Xen-users] Xen PV warning messages on boot

["Phil Quesinberry" <philq@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I'm trying to get a PV instance of CentOS 5.7 running on XCP.  I have 5.7
running in HVM mode on another box and it works fine but I would like to
maximize the VM's performance.

It ultimately boots up ok (without graphics) but starts out with the
following warnings:

rtc: IRQ 8 is not free
rtc: IRQ 8 is not free
i8042.c: No controller found.
Red Hat nash version 5.1.19.6 starting
  Reading all physical volumes.  This may take a while...
  Found volume group "VolGroup00" using metadata type lvm2
  2 logical volume(s) in volume group "VolGroup00" now active
                Welcome to CentOS release 5.7 (Final)
                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): Sun Feb........... and so on

Hardware is a Dell T610.  Is this normal, or does it mean that the VT-d is
not working on the hardware or something?  Apparently I'll need to configure
VNC to access a graphical console, which is fine.

Any way to eliminate these warning messages or should I not have any
concerns about running a server in this environment?

Many thanks,
