Where are the hw_disk_bus and hw_vif_model settings taken from on instance reboot?
I have an image which uses the hw_disk_bus and hw_cdrom_bus as format ide instead of virtio and the hw_vif_model as e1000 instead of virtio. I dont have drivers compatible with virtio for my image, so instead I change the properties of my glance image using glance image-update to reflect the hw_disk_bus and hw_cdrom_bus as ide and hw_vif_model as e1000. The image loads up fine the first time, however the reboot fails because the vif and disk bus models go back to virtio instead of using the new settings from the image. Any ideas on how to resolve this??
