I must relativate above: i have two test enviroments, one is our LiveCD/Install-ISO with 2.6.26 which we made special for a linux conference last weekend (our official iso comes still with 2.6.25). With this iso the "trick" with VT-x or noacpi works. But on an installed archlinux (with distribution kernel 2.6.26) this does'nt work. Sometimes it works when i restart the virtualbox application, but mostly not. So on this installed guest system the only working solution seems to add noreplace-paravirt as kernel parameter. But this makes the system terrible slow (mostly on udev things). I try Mathieu's hints currently by building a new distribution kernel with the changes. But i think the biggest problem to maybe solve this from the sight of kernel devs is that we all have different "test" enviroments (vbox versions, architectures, distribution kernels,...) where the oops (i think) not appears for all on the same place. On the other hand, the more we we try such patches in different enviroments there is a better chance to get a real fix - from kernel dev side or from virtualbox/Sun side... > Thanks for joining! > Luiz Fernando N.
