[Qemu-devel] [Bug 1769189] [NEW] Issue with qemu 2.12.0 + UEFI

["François Guerraz" <kubrick@fgv6.net>]

Public bug reported:

(first reported here: https://bugzilla.tianocore.org/show_bug.cgi?id=949
)

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.

** Affects: qemu
     Importance: Undecided
         Status: New
