Actual results:
Win2012r2 black screen and stuck after final reboot
last for at least 30mins before vm killed.
Expected results:
installation finished successfully, not stuck

Additional info:
1) this issue didnt observed when using aio=native (also 10 attemps)
2) after issue 'system_reset' in monitor, the guest would restart and finish the installation

Do you see this issue if you install windows using ide cdrom instead of scsi cdrom?
Only win2012 fails?
BTW, you probably mean scsi-hd instead of virtio-hd here.

Hi Asias,

> cdrom?

nope, this is found when using autotest, it would generate ide cdrom only when the hard drive is ide, I would try manually reproduce

> Only win2012 fails?

Win2012 works fine, only met this on win2012r2(preview though)

> BTW, you probably mean scsi-hd instead of virtio-hd here.

oh yes, thx for pointing this, corrected the typo in the summary.

Win2012r2 installation with virtio-scsi but aio=native :
