Hi,
Sure, the sources are here:
https://github.com/YanChii/illumos-kvm/tree/live-migration
https://github.com/YanChii/illumos-kvm-cmd/tree/live_migration
The (small) number of changes does not reflect the effort invested into
this. All dead ends and debugs are not present in the final patch :).
I just rebased and testing my changes to integrate latest commit into
illumos-kvm (regarding the coexistence with bhyve):

Hi Matt,
KVM live migration is possible and we are working on it right now.
The hardest part (the kernel & qemu support) is already done and
currently I'm able to successfully migrate the VMs. Now we need two
things:
1. integrate the patches into the illumos-kvm and illumos-kvm-cmd
repos (requires testing, reviews, etc.)
2. some userspace support (live migration script).
After merging the patches into SmartOS, we can focus on the userspace
part (or you can write your own migration script).

PS: in parallel with the above, the live migration will be present in
the Danube Cloud v3.0.0 expected in this December.

De-lurking for a moment to ask a question: is live migration of
zones and KVM VMs possible? I recall it has been mentioned on this
list before and I can find ageing references to it, e.g:
https://github.com/joyent/smartos-live/blob/master/src/vm/README.migration
I usually get by with vmadm send and vmadm receive after first
stopping the VM and that works great but it’s a bit of a chore
stopping and migrating dozens of VMs off a busy host when it needs
to go down for maintenance.
Cheers,
Matt.
