Hi all Till this morning, I ran Windows 10 client on VirtualBox 6.1.24 on host Centos 8 stream kernel 4.18.0-315.el8 without problem (desktop). I took the risk to do a "yum update" and as well as the kernel as the VirtualBox were updated: kernel going from 4.18.0-315.el8 to 4.18.0-326.el8 VirtualBox going from 6.1.24 to 6.1.26 But yum complained already : ...

Installed: SDL-1.2.15-39.el8.x86_64 VirtualBox-6.1-6.1.26_145957_el8-1.x86_64 Complete! Vbox did not start my Windows 10 when I tried. I also tried to install VirtualBox 6.0 and 5.2 with the same kind of error in yum. I rebooted then the computer and started a previous kernel 4.18.0-310.el8 and reinstalled Virtualbox 6.1.26 now without those errors and it runs smooth as before. (Kernel 315 had the same vbox errors.) However, when I went back to kernel 4.18.0-326 and tried starting there VirtualBox 6.1.26 again, he complained with : ... Failed to open a session for the virtual machine Windows10. Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing '/sbin/vboxconfig' as root. ... (I tried that "/sbin/vboxconfig" but that tells me nonsense about registering because of EFI secure boot, but I did not change anything in the BIOS.) or there is some conflict between the last kernels and VirtualBox? cheers mathy _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
