[avocado-vt]virsh hypervisor-cpu-compare报错

[lvxiaoqian555]

使用以下命令获取主机能力

virsh domcapabilities qemu /usr/bin/qemu-system-riscv64 riscv64

保存在 /var/lib/libvirt/images/avocado_9fujin2w/cpu.xml 中

然后使用命令比较主机上hypervisor创建的CPU

virsh hypervisor-cpu-compare /var/lib/libvirt/images/avocado_9fujin2w/cpu.xml --virttype qemu --error

会出现如下报错

error: File '/var/lib/libvirt/images/avocado_9fujin2w/cpu.xml' does not contain any <cpu> element or valid domain XML, host capabilities XML, or domain capabilities XML

cpu.xml中是有 <cpu> 相关的元素的，请问有哪位老师知道这是个bug还是我哪里配置不对吗？
