DESCRIPTION:Trusted Execution Environments (TEEs) are essential for cloud s
 ecurity\, with Confidential Virtual Machines (CVMs) as the prevailing appr
 oach. While proprietary solutions dominate deployments\, the RISC-V ecosys
 tem lacks mature open-source CVM implementations despite CoVE progress. Th
 is paper presents a VM-level TEE architecture on the open-source XiangShan
  RISC-V processor\, featuring physical isolation of Enclave Management Tas
 ks via dedicated secure cores. We implement bitmap-based page-granularity 
 memory isolation and multi-key memory encryption for fine-grained access c
 ontrol and software-defined full-memory cryptographic protection. Evaluati
 on on FPGA prototypes demonstrates minimal EMS area overhead (<1% of SoC a
 rea).
