各位大佬，小弟最近在研究KVS系统，因为不确定KVS是否能满足自己的需求，所以先购买了一个月的使用期，在搬瓦工上弄了个4G内存的VPS测试研究系统。
结果各种KVS需要的环境安装出错，无奈只能花了99美元请KVS的官方配置服务器，到了安装配置ffmpeg的时候KVS后台一直报错，KVS技术说是服务器CPU指令集权限不够，让我找VPS的技术支持要更高的指令集权限，然后搬瓦工那边又告诉我不能提供最高的CPU指令集权限。。。。WTF，前后各种花费快小两千了，结果现在一个完整的站点还没搭起来。。。请教各位大佬，有没有在搬瓦工上完整配置过ffmpeg的?系统是CentOS 7
具体报错的错误提示如下：

KVS技术跟我说如下：
Please ask your host support to switch the processor emulation mode on this server to host-passthrough , we need this for correct works of ffmpeg library.
We need this for ffmpeg, now we see error "ffmpeg: common/cpu.c:251: x264_cpu_detect: Assertion `!(cpu&(0x0000040|0x0000080))' failed." - that's easy to switch from "QEMU Virtual CPU version (cpu64-rhel6)" to " host-passthrough" or host support can't make this?
然后搬瓦工跟我说：
Unfortunately we are not able to offer host-passthrough cpuid at this time. Do you know what specific flag ffmpeg is looking for?
崩溃中。。。
