vi /etc/shelter.conf确保在opts行中进行了如下配置：
firmware = "/usr/share/edk2/ovmf/OVMF_CODE.cc"
opts = "-object sev-guest,id=sev0,policy=0x1,cbitpos=47,reduced-phys-bits=5 -machine q35,memory-encryption=sev0"然后运行shelter run cat /proc/cpuinfo。示例输出如下：

使用hag工具查询当前系统上正在运行的CSV guest个数：
hag csv platform_status假设系统中只有shelter创建的一个CSV guest，且shelter运行过程尚未结束。运行hag工具时，guest_count`行将显示为1：
api_major: 1
api_minor: 3
platform_state: CSV_STATE_WORKING
owner: PLATFORM_STATE_SELF_OWN
chip_secure: SECURE
fw_enc: ENCRYPTED
fw_sign: SIGNED
CSV: CSV CSV2
build id: 2011
guest_count: 1
is HGSC imported: YES
supported csv guest:15
platform_status command success!
[csv] Command successful!
注意：该行统计的只有CSV guest的个数，不包含非CSV guest的个数。
