Nova Instance Creation Fails with Error: USB is diabled for this domain

[Evan]

My instances fail to create and I get the following error in /var/log/nova-compute.log on the compute nodes and /var/log/nova-conductor.log on the controller nodeabout USB being disabled for a domain but devices being present in the domain.xml.

Fixed the USB Error by changing pointertype in nova.conf to ps2mouse.

[Sylvain Bauza (sylvain-bauza)]

Looks to me a config issue, not a project bug.

Wanted to update that I resolved this a while back. I had only used the 32 bit Ubuntu image for Raspberry Pi when only the 64 bit had the necessary files to support KVM. Reformatting with a 64 bit image resolved it.

Thanks for following up on this, Evan. We found this same problem on s390x architecture, the change
in the configuration as you mentioned did the trick, thanks for posting it :-) it saved me a lot of
time

[Evan (nesboy43)]

Glad to hear it helped!
