Can't setup kgdb with KVM, debug event not registered in sysrq-trigger ?

Hi,

I'm trying to setup kgdb with KVM guest, so I downloaded kernel source
3.8.8 from kernel.org, and compiled the kernel with the following
options enabled:

# CONFIG_SERIAL_KGDB_NMI is not set
CONFIG_HAVE_ARCH_KGDB=y
CONFIG_KGDB=y
CONFIG_KGDB_SERIAL_CONSOLE=y
# CONFIG_KGDB_TESTS is not set
CONFIG_KGDB_LOW_LEVEL_TRAP=y
# CONFIG_KGDB_KDB is not set

CONFIG_MAGIC_SYSRQ=y

CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_INFO=y

When I do 'echo g > /proc/sysrq-trigger', a 'sysrq HELP' message was
displayed on console, that means the debug event is not installed to
sysrq?

I can see the kgdboc module in /sys/modules/

Anyone know how to fix that?

P.S the guest is a centos 6.5 image, and booted directly from kernel bzImage
