Failed to hot set memory to VM. Underlying error message: unsupported configuration: unknown device type 'memory'
Last modified: 2016-02-18 05:50:50 EST
Description of problem:
Tried to expand memory from 2GB to 4GB on my VM, engine shows:
Failed to hot set memory to VM satellite. Underlying error message: unsupported configuration: unknown device type 'memory'
Version-Release number of selected component (if applicable):
Both engine and host are updated to oVirt 3.6.1 RC2 on CentOS 7.1
Steps to Reproduce:
1. create a VM with 2 GB of ram
2. boot it
3. hotplug other 2 GB of ram
It fails to hotplug ram
It should work
I still have the environment up, ping me in IRC if you want to inspect
you may be running wrong qemu (do you have qemu-kvm-ev 2.3+?) or wrong cluster level...
Where/whenhow did you create that VM?
qemu was right, looking at users mailing list it seems to be a libvirt version issue.
We should enforce minimum version in vdsm spec file in order to avoid this kind of issues.

- Which libvirt version do we need?
- Perhaps worth changing the bug title to 'depend on libvirt version ...'
since 3.6.1 we require RHEL/CentOS 7.2, so I don't think we need to do anything anymore
Re-rested yesterday on my local lab with CentOS 7.2, now worked.
