how to change emulator path during live migration

Hello libvirt experts, I am facing the following exceptions during live migrating a virtual machine from one compute node to another. file or directory: libvirt.libvirtError: Cannot check QEMU binary /usr/bin/kvm-spice: No such file or directory File "/var/lib/openstack/lib/python3.6/site-packages/eventlet/tpool.py", line 83, in tworker rv = meth(*args, **kwargs) File "/var/lib/openstack/lib/python3.6/site-packages/libvirt.py", line 1745, in migrateToURI3 if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) libvirt.libvirtError: Cannot check QEMU binary /usr/bin/kvm-spice: No such file or directory After some investigation, we found that this error is triggered because we do not have qemu-kvm installed in our container, btw the libvirt is directly installed on the source node. I have following questions Is it possible to change emulator during live migration? I try to to remove emulator under devices but looks like it does not help. thank you very much and looking forward for the feedback. -- Best Regards, Jiatong Shen
