[Xen-devel] [PATCH 3/8] tools: handle CQM resource when creating/destroying guests

[dongxiao.xu@xxxxxxxxx]

From: Dongxiao Xu <dongxiao.xu@xxxxxxxxx>

If a guest is created with parameter "pqos_cqm" set to 1, an RMID
will be allocated to the guest. This RMID will be relinquished when
guest is destroyed.
