Hi,

Sorry, I can not get the boot message through XenSerialConsole now. However,
attached are the screenshots of the last part of boot message.
If add "no-bootscrub" on the xen command line, the message is the same
except for the last line, "(XEN) Scrubbing Free RAM:". The grub.conf is as
following.

 title Xen-4.0 (Linux kernel 2.6.31.13)
    root (hd0,10)
    kernel /boot/xen-4.0.gz dom0_mem=1024M loglvl=all guest_loglvl=all
    module /boot/vmlinuz-2.6.31.13 root=/dev/sda1 ro nomodeset
    module /boot/initrd-2.6.31.13.img

Best wishes.

Gavin Guan
