VBox addtions do not work when using the hugemem kernel

[bernardg]

VBox video X11 additions do not work when using the hugemem kernel. Steps to reproduce:

• install centos or redhat (about version 4.6)
• install the hugemem kernel : Revision 2.6.9-67.ELhugemem

rpm -Uvh kernel-hugemem-2.6.9-67.EL.i686.rpm

• launch Linux with the hugemem kernel
• install the vbox additions
• reboot
• see Linux is starting to boot
• see Linux is even swapping to high res (1024)
• see the screen turns all black at the end of boot just before asking for log
• see the VM not replying anymore
• see that even ACPI shutdown does not reply anymore

If you are a registered Oracle customer for VirtualBox then please use My Oracle Support to get help.

Btw, RedHat 4.x / CentOS 4.x is not supported by upstream anymore.

Hi Frank Thanks. We are not a registered Oracle customer for VirtualBox but we are a registered company. What is upstream ? Regards

[Frank Mehnert]

"Upstream" is Redhat. Support for RHEL4 (CentOS4 bases on RHEL4) expired in 02/2012. I don't know the term registered company. Again, if you have a customer contract, please use the corresponding Oracle channel. This bug tracker is for community issues from normal users.

Also, as I understand from the documentation, the hugemem kernel is a 4G/4G kernel (the kernel lives in a separate 4GB address space from userland). VirtualBox did never support this kernel and most probably never will. If you need to address a lot of memory, use a 64-bit OS. With 32-bit OSes, recent Linux distributions can use up to 64G (still only 4G per address space).
