--- Comment #15 from Mario Lobo <l...@bsd.com.br> --- Hi here is my report. Host: stable/14-6060830201d6: Wed May 7 15:20:42 -03 2025 I had Vbox 7.0.24 installed: All VMs worked, except the Snow Leopard VM after installed Vbox 7.1.8: VMs that Boot Ok: Linuxes 32&64 bits (Debian, Ububtu and Fedora) Android 64 bits PF-Sense BSD 64 bits Windows 32 bits VMs that enter Guru Meditation: Snow Leopard ANY windows 64 bits, be it an existing VM or create a new one. No 64 bit Win ISO boots anymore (8,8.1,10,11, whatever) VirtualBoxVM --startvm Win10 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !! VCPU0: Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT) !! !! Skipping ring-0 registers and stack, rcErr=VINF_EM_TRIPLE_FAULT !! !! {mappings, <NULL>} !! !! !! {hma, <NULL>} !! >From this point on, the install of 7.1.8 "screwed" something in the system so bad that even if going back to older versions (7.0.24 or 6.1.50), VirtualBox is no longer capable of booting any windows 64 bits. The only exception is that Snow Leopard boots on 6.1.50. One last thing of note. During compilation, under EACH kbuild line, it shows: fcntl(): bad file descriptor -- You are receiving this mail because: You are on the CC list for the bug.
