Re: [Xen-users] Xen PV warning messages on boot
Don't have any concerns regarding the clock, those messages just meanthat the system was expecting a hardware clock and it didn't find one because of the way xen works with that.
Another think you should look at is the sysctl setting called xen.independent_wallclock which is set to 0 by default and if you change it to 1 you're able to adjust the time independently in the domu. This may get you rid of the clock messages you
have.

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

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,
