This probably because bios does not support virtio 1.0.

Michael, any plan to support this in 7.2?

bootable
    -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,disable-modern=on,disable-legacy=off,bus=pci.0,addr=04 \


=======

 un-bootable
 -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,disable-modern=off,disable-legacy=on,bus=pci.0,addr=04 \



same issue on virtio-blk-pci, change bug title accordingly

Seams dupl from bug 1242850

same issue as virtio-scsi cdrom

Since virtio-1.0 is tech-preview in 7.2 and libvirt won't enable it, I'm deferring this to 7.3.

I install and reboot a guest on ppc64le host with following qemu '-drive' devices, met the same problem as that in the bug: 

-device spapr-vscsi,id=scsi0,reg=0x1000 -drive id=drive_image1,if=none,cache=none,snapshot=off,aio=native,format=qcow2,file=/home/virtioblk-0814 -device virtio-blk-pci,id=image1,drive=drive_image1,bus=pci.0,addr=04,disable-legacy=on,disable-modern=off,bootindex=1 -drive file=/home/RHEL-7.2-20150806.1-Server-ppc64-dvd1.iso,if=none,id=drive-scsi0-0-0-0,readonly=on,format=raw,cache=none -device scsi-cd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=2


The sw versions are:

Host kernel: 3.10.0-302.el7.ppc64le
Guest kernel: 3.10.0-302.el7.ppc64/3.10.0-302.el7.ppc64le
Qemu-kvm-rhev: qemu-kvm-rhev-2.3.0-16.el7.ppc64le


So change the 'Hardware' field to 'All'.

planning to rebase seabios in 7.3, that should pick up virtio 1.0 support.

ppc uses different firmware (slof not seabios)
please open a separate bug (or clone this for slof).

Report bz1257128 for ppc, so change the 'Hardware' field to 'x86_64'.

Thanks!

Please retest with seabios 1.9.x build.

Hi Yanan,

Could you reply this?

Test with version:
kernel:kernel-3.10.0-396.el7.x86_64
qemu-img-rhev-2.6.0-1.el7.x86_64
seabios-1.9.1-4.el7.x86_64

1.virtio-scsi-pci
    1) scsi-disk ------> bootable
-device virtio-scsi-pci,disable-legacy=true,disable-modern=false,id=scsi \
-drive file=/root/RHEL-Server-7.3-64-virtio-scsi.qcow2,if=none,id=drive-scsi,media=disk,format=qcow2,cache=none \
-device scsi-disk,drive=drive-scsi,id=scsi-0,bus=scsi.0,bootindex=0 \

    2).scsi-cd ------> bootable
-device virtio-scsi-pci,disable-legacy=true,disable-modern=false,id=scsi \
-drive file=/root/RHEL-7.2-20151027.3-Server-x86_64-dvd1.iso,if=none,id=drive-scsi,media=cdrom,format=raw,cache=none \
-device scsi-cd,drive=drive-scsi,id=scsi-0,bus=scsi.0,bootindex=0 \

2.virtio-blk-pci ------> bootable
-drive file=/root/RHEL-Server-7.3-64-virtio-blk.qcow2,if=none,id=drive-blk,media=disk,format=qcow2,cache=none \
-device virtio-blk-pci,drive=drive-blk,id=virtio-blk-disk,bus=pci.0,bootindex=0,disable-legacy=true,disable-modern=false \



As the test result above, i think this bug is ok with seabios-1.9.1-4.

Retest with latest qemu-kvm-rhev for rhev 7.2:

qemu-kvm-rhev-2.3.0-31.el7_2.13.x86_64
kernel:kernel-3.10.0-396.el7.x86_64
seabios-1.9.1-4.el7.x86_64

Test results are same with above.

> As the test result above, i think this bug is ok with seabios-1.9.1-4.

Yes, as expected, as the 1.9 rebase brings virtio 1.0 support in seabios.

marking as dup of the 1.9.1 rebase bug
