The option is not without cost. It reduces the address space available to UML processes. Since the B000 split seems to be Debian-specific, you might add a corresponding Debian-specific patch to UML which defines the top of the address space to B000, rather than A000, which CONFIG_HOST_2G_2G does.

Thanks, will enable it in the .17 release of the debian package. -- mattia :wq! --- Using Tomcat but need to do more? Need to support web services, security?

Does this mean that UML will run on a non-standard-vm-split _only_ if the host has CONFIG_VMSPLIT_2G=y ? If so is this considered a bug or a feature? :) Thanks a lot -- mattia :wq! --- Using Tomcat but need to do more? Need to support web services, security?

The host will only have a nonstandard split if it has CONFIG_VMSPLIT_2G or equivalent enabled. Do you instead mean whether UML will run on a nonstandard split host if IT (not the host) has CONFIG_HOST_2G_2G (not CONFIG_VMSPLIT_2G) enabled? If so, the answer for now is yes. > If so is this considered a bug or a feature? :) More a bug. We are considering ways of detecting the host vmsplit at run time and adapting to it, but added back the CONFIG_HOST_2G_2G as an interim measure. Jeff --- Using Tomcat but need to do more?
