2015-05-03 15:27:36 -0500 answered a question How to make volume using IDE bus

My VM uses cinder volume which is copied from glance on machine boot. If I boot VM directly from glance VM runs with IDE disk. If I boot VM from image wich creates new volume - this new volume is on VirtIO bus and VM fails to boot.

How to make sure cinder volume inherit all glance image properties?

How to specify these properties from GUI?

2015-05-02 20:12:58 -0500 asked a question How to make volume using IDE bus

Hi, I have glance image with property hw_disk_bus = ide then it boots fine. When I make volume from the image and then boot new instance it fails to boot because volume is not on ide bus and OS has no appropriate drivers.

What is the default bus for cinder volumes? How can I change this bus to IDE from Openstack dashboard?

I know how to boot new instance from volume supplying volume with IDE bus but I'm unable to find a way how to do that without using CLI

2015-04-17 03:15:32 -0500 commented question instance failed to create due to block device setup timeout

Ceph is ok and as I said problem is only with time it takes to download large images to/from ceph. This issue is connected to known bug #1332382. Sad to know its fixed only in latest versions and I need to manually fix this value in Python code now on all my compute nodes.

Hi, Im using Icehouse with Ceph over 1G network interfaces. When I try to create instance with some big volume on RBD storage backend it fails with errors in log

I see creating block device in Ceph takes much more time then Nova waits. How can I tune this timeout and attempts number in Nova?
