Eden (anthony.louis.eden@gmail.com) --- > By "the kernel", I assume you mean the guest kernel? Yes, the guest kernel. I can no longer interact with the VM via the serial console. It is unresponsive. I attached a debugger to qemu-system-x86_64 to see if qemu itself was in an infinite loop or something but the stacktraces all looked normal. > Is this a regression or something that has always been broken? I.e. did = this > work on previous host kernels? I do not know whether this has always been broken or not. --=20 You may reply to this email to add a comment.
