Hello guys, We have a situation where an image requires an IDE bus in KVM. Therefore, we configured it in OpenStack to have the IDE bus being used. However, when we add new volumes to this VM (server), all of them are being allocated as IDE volumes; therefore, we are limited to 4 volumes in total in the VM. Is it possible to mix different types of volumes in a VM in OpenStack? I know that in other platforms, such as when we use KVM directly, proxmox, Apache CloudStack, we can do such combinations, but we were not able to achieve it in OpenStack.
Have you guys worked with similar use cases? I know that I can convert the image to use virtIO or iSCSI bus, and to do that I need to fix/patch the operating system inside the image. However, I would like to check if there is a method to use a root volume of a VM as IDE, and other volumes as virtio to avoid the limit of volumes that IDE has.
Hi,
I think I heard some Nova people talking about a new feature to support different buses for different volumes. Unfortunately I don't remember if it's something they were considering doing or something they were already working on. it was something we were considering supporting in the future if someone volenterred to work on it. i was suggesting it shoudl be a preriqustit to supprot vdpa for cinder volumes in the futrue.
Thanks Sean! That was precisely the conversation I had in my mind but couldn't remember the details. :-)
