Public bug reported: RequestedVRamTooHigh can be raised during server create from the libvirt driver if the flavor's max video ram is less than the hw_video_ram specified in the image, and because the compute manager isn't handling that specific exception, it will result in a RescheduledException to another compute host, but this is never going to work on another compute host so we should just handle it and abort the build, since it's user- error.
Long-term, we should be validating this in the REST API instead of on the compute although not all virt drivers support the image property and flavor extra spec - currently only the libvirt driver does but there is also a patch to add support for it with the vmware driver: https://review.openstack.org/#/c/564193/ https://github.com/openstack/nova/blob/bfcbfdf9169765219320abfa3e09ecda8ff1a80c/nova/virt/libvirt/driver.py#L4608 https://github.com/openstack/nova/blob/bfcbfdf9169765219320abfa3e09ecda8ff1a80c/nova/compute/manager.py#L2095 ** Affects: nova Importance: Medium Assignee: Matt Riedemann (mriedem) Status: In Progress ** Tags: compute libvirt ** Changed in: nova Status: New => Triaged ** Changed in: nova Importance: Undecided => Medium -- You received this bug notification because you are a member of Yahoo!
