Yes, I do. The problem is that the console breaks as soon as you set CONFIG_XEN_PHYSDEV_ACCESS is set to y. With that setting CONFIG_VT_CONSOLE, CONFIG_HW_CONSOLE, CONFIG_VGA_CONSOLE, etc. are set to 'y' and there is no way to turn them off again. You may edit .config and do a 'make ARCH=xen oldconfig', but afterwards those flags are turned back to 'y'. I changed the Kconfig files that define those flags to force them to the off-state. Afterwards there is some output: xm create -c zzzz Using config file "/etc/xen/zzzz".

It is a domain with physical device access but with not a privileged guest. -- Gruss, Tobias ------------------------------------------------------------ Tobias Hunger The box said: 'Windows 95 or better' tobias@xxxxxxxxxxx So I installed Linux. ------------------------------------------------------------ Attachment:
