Cannot dispatch VM: No host meets capacity and sched_requirements

There is an UI issue that incorrectly give “(HOST_ID = 20)”
It needs to be (ID = 20)

where 20 is whatever physical host number your are trying to force assignment to vs the scheduler picking any host with available resources in your cluster.

please see this post for more details:

After some significant debugging and reviewing the Scheduler.cc code I found the issue/WebUI bug. This works: (HYPERVISOR=kvm) & (ID = 20) WebUI give this by default: (HYPERVISOR=undefined) & (HOST_ID = 20) It was somewhat obvious to change “undefined” to “kvm” but the HOST ID… well that took a few days to figure out. === Debugging Details Workaround # was to put HOST_ID as an attribute on each host, but that wasn’t the best fix. The HOST have an “ID” value, but needed to have “HOST_ID”…
