The user provided some logs from QEMU which show that the VM (Layer 1) is terminating because of a signal 15. They mentioned it's similar to a known QEMU seabios failure, but in their case, they're using OVMF instead. + +First, I should understand what each part of the log means. The logs include CPU registers and segment information all set to zero, which might indicate an issue during VM initialization or reset. The fact that EIP is 0 suggests that the instruction pointer isn't pointing to any valid code, possibly leading to a crash or hang. + +The user notes that they tested with Q35 versions 3.1 and 2.12 without success. They also mention that due to a FreeBSD networking bug, they had to disable the netmap driver, which is a separate issue. However, their main problem seems to be with how bhyve interacts with OVMF under Linux. + +I recall that bhyve is FreeBSD's hypervisor and relies on QEMU for hardware emulation. The user mentioned cross-posting this bug to FreeBSD's bugzilla as well. So the issue could be either in QEMU, bhyve, or the interaction between them when running on a Linux host. + +The fact that nested virtualization works correctly under Ubuntu suggests it's specific to the FreeBSD host/guest setup. Perhaps there's an issue with how OVMF is initialized or interacts with the hypervisor on FreeBSD compared to other setups. + +I should look into known issues with bhyve and OVMF, especially regarding VM initialization failures. Maybe there are specific flags or configurations that need to be set when using OVMF under bhyve, which aren't currently being used. Alternatively, the problem might be related to how the CPU mode is handled (like long mode in 64-bit) or how certain registers are initialized. + +Also, since the user had a networking issue with netmap disabled, maybe there's an interaction between the network configuration and other VM components that causes the crash. However, they mentioned it's a known bug, so perhaps focusing on the VM initialization failure is more pressing. + +In summary, I think the main points to consider are: + +1. Investigating whether OVMF has specific requirements under bhyve that aren't being met. +2. Checking if there are known issues with QEMU seabios/OVMF interactions in FreeBSD's bhyve environment. +3. Reviewing how CPU registers and segmentations are initialized during VM startup to ensure they're set correctly, especially since EIP is at zero. + +I might need to look for similar bug reports or patches related to bhyve and OVMF initialization failures. Additionally, verifying if there are any missing configurations in the VM setup that could cause such an issue would be helpful. +</think> + +The problem appears to stem from an initialization issue with the FreeBSD VM (Layer 1) under bhyve on a Linux host, using OVMF firmware. The QEMU logs show that the VM terminates due to signal 15, possibly related to improper setup of CPU registers or segments during startup. + +To resolve this: + +1. **Check Configuration**: Ensure OVMF is correctly configured for use with bhyve. Verify any necessary flags or settings in the hypervisor. + +2. **Investigate Known Issues**: Look into existing bug reports or patches regarding QEMU, seabios, and OVMF interactions under FreeBSD's bhyve to see if similar issues have been addressed. + +3. **Review VM Initialization**: Examine how CPU registers, especially EIP, are initialized during startup. Ensure they point to valid code to prevent crashes. + +By addressing these areas, the initialization failure in the FreeBSD VM should be resolved, allowing it to run correctly under bhyve with OVMF. \ No newline at end of file |
