Re: [libvirt] [PATCH RFC V2 1/2] Resctrl: Add new xml element to support cache tune

This patch adds new xml element to support cache tune as: <cputune> ... <cachetune cacheId='0' type='both' sizeKiB='2816' vcpus='0,1'/> ... </cputune> cacheId: reference of the host's cache banks id, it's from capabilities xml. type: cache bank type, it could be both, code, data. sizeKiB: must be multiple of granularity, must be greater than or equal to minimum.

vcpus: cache allocation on vcpu set, if empty, will apply the allocation on all vcpus.
