Why is that needed at all ? We have out-of-the-box working KVM on our appliances without the need to modify the system initrd ? The build script defaults to ext3 anyway and if you don't change the values in sysconfig the initrd get anyway replaced again on next kernel update. So I dislike this hint atm, because it will create problems later. bye adrian -- Adrian Schroeter SUSE Linux Products GmbH email: adrian@suse.de -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

Then I correct the comment in that sense that: - if you want or need to use an own kernel with the KVM setup - then you need to make sure that the initrd contains the modules listed - and want to default to ext4 in the KVM setup, then you have to make export rootfstype="ext4" You say the initrd defaulting in /boot is working. Then I can comment like that. Let me try it out. Do you suggest that: - switching on KVM should automagically work - what about a missing vitio module in the initrd Martin -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
