Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I need to increase screen resolution to 1024x800 for all 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 boots arguments are ignored during startup. Probably inside XenSever /boot it's 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.

Pls help. Thanks Max

have you tried adding extra="vga=791" in your domU-vmname.cfg file? That will set permanent kernel parameters for domain. For single kernel argument passing use xm create domU-vmname.cfg extra="vga-791"
