I have tried everything to get slowroll to work - tumbleweed migrate, leap 15.5 migrate - none work as zypper dup does not update to a working slowroll it will install tumbleweed and fail to zypper dup to slowroll. I have created 24 different vms that have not worked a zypper dup to a valid result.

Slowroll will update to the 6.4.24 kernel and get deleted because the install image put 6.5.3 kernel and the reboot deletes the 6.4.24.

Can someone make a valid slowroll install iso and not install tumbleweed but a true slowroll?

I would take a slowroll virtualbox vm that works. I have no idea how to set virtualbox to work with slowroll - it seems to get recreated with every Tumbleweed kernel but seems to be backward compatible.
