The options CONFIG_VT, CONFIG_VT_CONSOLE, CONFIG_HW_CONSOLE and CONFIG_VGACONSOLE are not listed in menuconfig. Commenting them out in the .config file will not work either: make readds them before building. The only way to stop those flags from appearing is to "depend !ARCH_XEN" in the Kconfig files where they are defined (I guess/hope there are less intrusive ways, but so far I never had to tweak the kernel build system). Turning the options off results in no output after the initial text from xen, informing me about kernel used, etc. xencons=off behaves the same way. I have no way to interact with the VM but the console, so I am not sure whether this works or not. The -xenU kernels work and give output, but is lacking the necessary HW support I need. PS: Being able to catch kernel panics in screen is so cool! I really like Xen, even though so far I have not managed to set it up completly:-) -- Gruss, Tobias ------------------------------------------------------------ Tobias Hunger The box said: 'Windows 95 or better' tobias@xxxxxxxxxxx So I installed Linux. ------------------------------------------------------------ Attachment:
