And I found that building a 2.6.19 kernel with identical configuration takes 845 sec on a guest and 210 sec on the host. So the compile is about 4X slower on the guest :( The guest ran with 2.6.19 kernel and host ran with a 2.6.20-rc5 kernel. The guest file image is created with raw format. Wonder if people see similar performance figure? Tim ------------------------------------------------------------------------- Take Surveys. Earn Cash.
