Hello community,

I’ve got a question related to the raw device mapping to the OpenStack virtual machine. The situation is I have several SSDs along with my compute node and I would like to attach these SSDs to my virtual machine for enhancing the disk performance. My current solution is using command “virsh attach-disk <dom> <host-device> <guest-device>” but it not persistently and need to manual re-attach after hard-rebooting which lead to re-generate the xml vm structure.

So, I wonder if there is an official solution for my problems. Thank you and welcome for every help in our community.

Best regards,

Sang Tran
