The solution for me is only dowgrading for now. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1769189 Title: Issue with qemu 2.12.0 + UEFI Status in QEMU: New Bug description: (first reported here: https://bugzilla.tianocore.org/show_bug.cgi?id=3D949 ) I had a Windows 10 VM running perfectly fine with OVMF UEFI, since I upgraded to qemu 2.12, the guests hangs for a couple of minutes, works for a few seconds, and hangs again, etc. By "hang" I mean it doesn't freeze, but it looks like it's waiting on IO or something, I can move the mouse but everything needing disk access is unresponsive. What doesn't work: qemu 2.12 with OVMF What works: using BIOS or downgrading qemu to 2.11.1. Platform is arch linux 4.16.7 on skylake, I have attached the vm xml file.
