I need to increase screen resolution to 1024x800 for my XEN console.
I tried to place
at the end of kernel line the file
/boot/grub/grub.conf but it seems that most of the boot arguments are ignored during startup. Probably inside XenSever /boot is not really used in order to launch CentOS.
I even tried to add boot option in the boot option tab (VM -> Property -> Boot Option) but doesn't work.
