显示版本有问题，经过排查并不qemu 或libvrit版本问题

发现virsh version提示有问题,messages日志里面也有很多qemu报错

[root@compute ~]# virsh version
Compiled against library: libvirt 4.5.0
Using library: libvirt 4.5.0
Using API: QEMU 4.5.0
error: failed to get the hypervisor version
error: internal error: Failed to probe QEMU binary with QMP: /usr/libexec/qemu-kvm: symbol lookup error: /usr/libexec/qemu-kvm: undefined symbol: epoxy_eglExportDMABUFImageQueryMESA

解决办法:

yum install libepoxy -y
