我正在尝试从服务器获取VM的故障转储，并使用命令
virsh dump domain_name file_name --verbose
但是virsh dump的手册页说，在上述情况下生成的文件无法由崩溃实用程序读取，因此应使用--memory-only选项。但是，即使（virsh dump domain_name file_name --memory-only --verbose）导致转储崩溃也无法正确读取。这是崩溃所说的
WARNING: cannot determine physical base address: defaulting to 0
crash: read error: kernel virtual address: ffff96a9c1812830 type: "possible"
WARNING: cannot read cpu_possible_map crash: read error: kernel virtual address: ffff96a9c1812760 type: "present"

WARNING: cannot read cpu_online_map crash: read error: kernel virtual address: ffff96a9c1812810 type: "active"
WARNING: cannot read cpu_active_map crash: vmlinux and vmcore do not match!
我当前正在CentOS 7.6，Linux Kernel 3.10.0-957和GDB 7.6上运行
如何使用virsh命令获取转储，崩溃实用程序可以读取该转储？
