I'm trying to add a switch to send linux kernel log to the serial console on XenServer6.
The kernel command options can be edited on the EXTLinux config file ( /boot/extlinux.conf ).
Here is an excerpt:
serial 1 115200
default xe
prompt 1
timeout 50
label xe
# XenServer
kernel mboot.c32
append /boot/xen.gz mem=1024G dom0_max_vcpus=4 dom0_mem=752M lowmem_emergency_pool=1M crashkernel=64M@32M console= vga=mode-0x0311 --- /boot/vmlinuz-2.6-xen root=LABEL=root-tfnnfzfp ro xencons=hvc com2=115200,8n1 console=com2 console=hvc0 console=tty0 quiet vga=785 splash --- /boot/initrd-2.6-xen.img
label xe-serial
# XenServer (Serial)
kernel mboot.c32
append /boot/xen.gz com1=115200,8n1 console=com1,vga mem=1024G dom0_max_vcpus=4 dom0_mem=752M lowmem_emergency_pool=1M crashkernel=64M@32M --- /boot/vmlinuz-2.6-xen root=LABEL=root-tfnnfzfp ro console=tty0 xencons=hvc console=hvc0 --- /boot/initrd-2.6-xen.img
What is the meaning of the triple dashes ( --- )on the command line?
Is it loading 3 boot files?
