https://bugzilla.suse.com/show_bug.cgi?id=1217342 Bug ID: 1217342 Summary: VirtualBox: Starting VM hangs if hosts system uses newer kernel Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: x86-64 OS: openSUSE Leap 15.5 Status: NEW Severity: Normal Priority: P5 - None Component: Virtualization:Other Assignee: virt-bugs@suse.de Reporter: ceggers@arri.de QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 870854 --> https://bugzilla.suse.com/attachment.cgi?id=870854&action=edit dmesg output after trying to start a VirtualBox VM Machine: DELL Precision 5680 In order to get sound on this machine running, I was forced to install a contemporary kernel (6.6.0-lp155.8) from the Kernel:stable:Backport:standard repository (sound works fine after installing this kernel, latest Alsa libs AND sof-firmware). Unfortunately, VirtualBox runs not fine at all. I installed the KMP (in the same version) from Kernel:stable:Backport:KMP:standard and VirtualBox starts without complaining about missing modules (and I see vboxnetadp, vboxnetflt and vboxdrv in the output of lsmod). But when I try to run a virtual machine, the sidebar shows only a progress bar "VM hochfahren ..." , stuck at 20%. Additionally I get much output in the kernel log (see attached file). I have the same problem with different virtual machines (Windows 11, openSUSE). When booting the host system with the openSUSE Leap 15.5 stock kernel (currently 5.14.21), VirtualBox VMs run fine. -- You are receiving this mail because: You are on the CC list for the bug.
