Virtual machines not working anymore on 2.10
Using 2.10, my virtual machine(s) don't work anymore. This happens 100% of the times.
-----
I use QEMU compiling it from source, on Ubuntu 16.04 amd64. This is the configure command:
configure --target-list=x86_64-softmmu --enable-debug --enable-gtk --enable-spice --audio-drv-list=pa
I have one virtual disk, with a Windows 10 64-bit, which I launch in two different ways; both work perfectly on 2.9 (and used to do on 2.8, but I haven't used it for a long time).
This is the first way:
qemu-system-x86_64
-drive if=pflash,format=raw,readonly,file=/path/to/OVMF_CODE.fd
-drive if=pflash,format=raw,file=/tmp/OVMF_VARS.fd.tmp
-enable-kvm
-machine q35,accel=kvm,mem-merge=off
-cpu host,kvm=off,hv_vendor_id=vgaptrocks,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time
-smp 4,cores=4,sockets=1,threads=1
-m 4096
-display gtk
-vga qxl
-rtc base=localtime
-serial none
-parallel none
-usb
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device virtio-scsi-pci,id=scsi
-drive file=/path/to/image-diff.img,id=hdd1,format=qcow2,if=none,cache=writeback
-device scsi-hd,drive=hdd1
-net nic,model=virtio
-net user
On QEMU 2.10, I get the `Recovery - Your PC/Device needs to be repaired` windows screen; on 2.9, it boots regularly.
This is the second way:
qemu-system-x86_64
-drive if=pflash,format=raw,readonly,file=/path/to/OVMF_CODE.fd
-drive if=pflash,format=raw,file=/tmp/OVMF_VARS.fd.tmp
-enable-kvm
-machine q35,accel=kvm,mem-merge=off
-cpu host,kvm=off,hv_vendor_id=vgaptrocks,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time
-smp 4,cores=4,sockets=1,threads=1
-m 10240
-vga none
-rtc base=localtime
-serial none
-parallel none
-usb
-device vfio-pci,host=01:00.0,multifunction=on
-device vfio-pci,host=01:00.1
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device usb-host,vendorid=0xNNNN,productid=0xNNNN
-device virtio-scsi-pci,id=scsi
-drive file=/path/to/image-diff.img,id=hdd1,format=qcow2,if=none,cache=writeback
-device scsi-hd,drive=hdd1
-net nic,model=virtio
-net user
On QEMU 2.10, I get the debug window on the linux monitor, and blank screen on VFIO one (no BIOS screen at all); after 10/20 seconds, QEMU crashes without any message.
On 2.9, this works perfectly.
-----
I am able to perform a git bisect, if that helps, but if this is the case, I'd need this issue to be reviewed, since bisecting is going to take me a lot of time.
