Does Virtualbox 7.x support Linux Kernel 4.19.x?

[brunni]

hi all

from my vbox-setup.log in my attempt to upgrade from 6.x to 7.x on Kernel 4.19.312:

Code: Select all

In file included from /tmp/vbox.0/include/iprt/assert.h:45,
                 from /tmp/vbox.0/include/VBox/sup.h:44,

                 from /tmp/vbox.0/SUPDrv.c:43:

This person had the same problem with an EOL kernel but 4.19.x is not EOL: forums dot gentoo dot org/viewtopic-p-8771139.html?sid=95fd6a050da46395987dbb665746d030

So does Virtualbox 7.x support Linux kernel 4.19.x? If not, where can I find a list of supported kernels? It seems Oracle itself will not help with this: www dot virtualbox dot org/ticket/17055

where can I find a list of supported kernels?

Oracle kernel support page info is 4yrs old, last update, though most the info is much older...

Thank you. It is indeed probably not the kernel version - something seems to be failing with the new macro check

RT_BF_ASSERT_COMPILE_CHECKS(VMX_BF_EPT_PT_, UINT64_C(0), UINT64_MAX,
(READ, WRITE, EXECUTE, MEMTYPE, IGNORE_PAT, IGN_7, ACCESSED, DIRTY, EXECUTE_USER, IGN_59_11,
SUPER_SHW_STACK, IGN_62_61, SUPPRESS_VE));

in include/VBox/vmm/hm_vmx.h as I get errors for

VMX_BF_EPT_PT_0_MASK
VMX_BF_EPT_PT_1_MASK
VMX_BF_EPT_PT_0_SHIFT
VMX_BF_EPT_PT_1_SHIFT

being undeclared. 0 and 1 in those macro names apparently should be one of items in the fourth argument for RT_BF_ASSERT_COMPILE_CHECKS.

Maybe some unexpected header file on my system causes this (defining READ/WRITE as 0/1?) or my gcc (version 10.4.0) needs upgrading. As I am not running a supported distribution, I'll have to look deeper into this.

The VirtualBox User Manual (7.0.18), Section 2.4 describes those Linux Host systems and kernel versions officially supported. Kernel '4.x' is still in the supported list.
