Hi all, 1, This issue is caused by the following 2 commits in upstream kernel: 9c573cd31343 randomize_kstack: Improve entropy diffusion ef40d28f17bd randomize_kstack: Remove non-functional per-arch entropy filtering
But only virtualbox 6.1.50 will crash. VirtualBox 6.1.x is no longer supported! Which is anounced by virtualbox.org. So it's a bit hard to push kernel changes for an unsupported application. I will file an upstream bug to try. 2, virtualbox 7.0.20 from virtualbox.org will work well on all the kernel versions. Please use virtualbox 7.0.20 if you can. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Triaged ** Changed in: linux (Ubuntu) Assignee: (unassigned) => AaronMa (mapengyu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/2073267 Title: Guru meditation on VM start Status in linux package in Ubuntu: Triaged Status in linux-signed-hwe-5.15 package in Ubuntu: Confirmed Status in virtualbox package in Ubuntu: Confirmed Bug description: It worked yesterday, but today I get a Guru Meditation trying to start some of my virtual machines. This shows up in VBox.log as "VCPU0: Guru Meditation -2708 (VERR_VMM_SET_JMP_ABORTED_RESUME)". I suspect this may have started due to a Linux kernel upgrade I installed this morning. A fresh VM with no disk shows the issue. Sometimes turning off the I/O APIC makes the issue go away, sometimes not. Turning off nested paging sometimes lets VirtualBox make a little bit of progress w.r.t. booting VMs, but that usually still crashes before the VM finishes starting.
