Subject: Re: [dts] [PATCH V1] framework/qemu_libvirt: rm ssh keygen	before	connect to vm

Message-ID: <B8B15C44A3F2C044966E545C7B7371153E84DA84@shsmsx102.ccr.corp.intel.com> (raw)

Hi,ma lihong

When dts is running on tester node(tester/dut not the same node), these code change the tester ssh config.

But virtual machine is running on dut, virtual machine's ip address is assigned by dut/qemu and is managed by  dut/libvirt tool.
