[libvirt-users] Unable to migrate vm from redhat to ubuntu using virsh migrate
Hello All, I am working on migrating the vm from redhat to ubuntu. the emulator value is as below. Ubuntu: <emulator>/usr/bin/qemu-system-x86_64</emulator> redhat: <emulator>/usr/libexec/qemu-kvm</emulator> When i try to migrate from redhat, i get the following error. It would be great help if you can suggest how to workaround the issue. virsh migrate --live --verbose --persistent vm1 qemu+ssh://host-3/system error: Cannot check QEMU binary /usr/libexec/qemu-kvm: No such file or directory Thanks in advance, Mani

Create a symlink?

It's going to need much more than that. Different versions of QEMU, with different settings, features etc.

That API provides you with the possibility of changing the destination xml, see 'man virsh', the parameter --xml should do what you want. If you want to automate this change between such hosts, you can do that with hooks [1]. Martin [1] http://libvirt.org/hooks.html
Thanks in advance, Mani

I'd really recommend you to to try to do this, it'll give you no end of pain & suffering. The different file path is the least of your worries. Much more critical is having compatible guest ABI machine types for both distros. Neither distro claims & attempts to maintain such ABI compat. This will likely cause live migration to crash & burn.
