MacOS Hypervisor Framework broken with Qemu. #268

Closed ExternalReality closed 5 years ago

ExternalReality commented 5 years ago

On mac, if acceleration is enabled in the run-time config, Ops will add the -accel hvf -cpu host flags to its generated Qemu Command. This causes an error.

signal: abort trap

Given this once worked unfailingly, I am guessing its a kernel regression.

@ExternalReality Which version of qemu are you using here? And which were you using before the regression?
