I don't think it is possible that the fix for AHCI would have any impact on virtio-scsi devices. If you're seeing issues in virtio-scsi, I'd make a new writeup in a new LP. --js -- = 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 + SATA Status in QEMU: Fix Committed Bug description: [EDIT: I first thought that OVMF was the issue, but it turns out to be SATA] I had a Windows 10 VM running perfectly fine with a SATA drive, 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 SATA What works: using VirIO-SCSI with qemu 2.12 or downgrading qemu to 2.11.1= and keep using SATA. Platform is arch linux 4.16.7 on skylake and Haswell, I have attached the vm xml file. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1769189/+subscriptions
