Linux VMs crashing (I did not test Windows guest VMs) Product: Virtualization Version: unspecified Hardware: All OS: Linux Status: NEW Severity: blocking Priority: P3 Component: kvm Assignee: virtualization_kvm@kernel-bugs.osdl.org Reporter: adolfotregosa@gmail.com Regression: No Created attachment 308028 --> https://bugzilla.kernel.org/attachment.cgi?id=3D308028&action=3Dedit journalctl I found a kernel regression. I'm using Proxmox, and any kernel with the following commit: https://github.com/torvalds/linux/commit/f9e54c3a2f5b79ecc57c7bc7d0d3521e46= 1a2101 causes an instant VM crash in some situations that involve GPU acceleration. I=E2=80=99m using an NVIDIA GPU passthrough, but another person experienced= the same crashes with an AMD 9070 XT. In my case, this occurs when playing a simple YouTube video in Chromium-based browsers or when running some games. I have confirmed that reverting this commit prevents my Linux VMs from crashing. I=E2=80=99ve attached a log showing what the host=E2=80=99s journalctl log = displays. The error is always exactly the same. --=20 You may reply to this email to add a comment.
