Public bug reported:
After upgrading compute nodes from mitaka to newton we are not able to migrate
virtual machine.
We are not able to migrate VMs from recently onboarded compute nodes to old
compute nodes that has been upgraded to newton.
Reason is:
Xenial-mitaka nova-compute (2.13) depends on nova-compute-kvm which does not
depend on qemu-kvm:
Package: nova-compute-kvm
Architecture: all
Depends: nova-compute-libvirt (= ${binary:Version}),
qemu-system (>= 1.3.0) | kvm,
${misc:Depends},
Newton nova-compute (2.14) package depends on nova-compute-kvm which depends on
qemu-kvm or qemu-system:
Package: nova-compute-kvm
Architecture: all
Depends: nova-compute-libvirt (= ${binary:Version}),
qemu-kvm | qemu-system (>= 1.3.0) | kvm,
${misc:Depends},
When we install newton nova-compute from scratch on compute node we have
qmu-kvm package installed => all virtual machines created on this compute node
are using kvm-spice emulator
When we upgrade nova-compute package from Mitaka to Newton, we don't
have qemu-kvm package installed => all virtual machines created on this
compute node are using qemu-system-x86_64 emulator.
