running mga8 as Client in mga7 causes VboxClient to segfault:

OK to assign this directly to you, Thomas?

Comment 2 Dave Hodgins 2020-04-16 20:59:22 CEST 
What, if anything other then booting is being done to trigger the segfault?

On my m7 host running 5.5.15-desktop-3.mga7 using the radeon video kernel module,
with an m8 guest running 5.6.4-desktop-1.mga8, no segfault here.

Adding audit=0 to the kernel parameters suppresses the audit messages from
the journal.

Based on the libX11.so.6.3.0 library, I gather the segfault was in the host,
but virtualbox rpm package on m7 is virtualbox-6.0.18-1.mga7

Is an cauldron version of the virtualbox package being used on a Mageia 7
system?

Comment 3 Marc Krämer 2020-04-16 21:56:06 CEST 
to clarify:
Host: mga7, kernel: 5.5.15-desktop-3.mga7, video: intel_drv.so, virtualbox:
dkms-virtualbox-6.0.18-1.mga7.noarch
virtualbox-6.0.18-1.mga7.x86_64
virtualbox-kernel-5.5.15-desktop-3.mga7-6.0.18-11.mga7.x86_64


Client: mag8, kernel: 5.6.4-desktop-1.mga8, video virtualbox:
virtualbox-guest-additions-6.1.4-2.mga8.x86_64

just noticed the above entry be accident in journal.
Comment 4 Thomas Backlund 2020-04-16 23:24:51 CEST 
Yeah, I will switch Mageia 7 to the 6.1 branch too in order to get better support / co-existence with Mga7 and Mga8 / Cauldron.

It should probably hit testing repos today / tomorrow

Fixed.
Updated Virtualbox version has landed M7.
