Virtual disk shared between VMs

asked 2014-05-16 06:17:43 -0500

Hello, i'm new in OpenStack and i have a question. I'd like to know if with OpenStack can share the same disk between two virtual machines over a virtual iscsi, just the same like in VMware, or only attaching the same disk to the two VMs is shared? Thanks all

Your question is comparing OpenStack with VMware, which is something of an apples-vs-oranges comparison: VMware is a hypervisor, while OpenStack is more of a resource scheduler that can distribute compute workloads to your hypervisor. You can actually use VMware in OpenStack in place of something like KVM. However, in answering your question, the capabilities of a particular hypervisor aren't relevant.

The OpenStack block storage service -- Cinder -- does not currently support attaching volumes to more than one instance at a time. There is work going on to enable this feature; you can read details here:
