Re: Deploying libvirt with live migration

Even if your not sharing /etc/libvirt, if you have migrated at least once, both systems see the VM's as available for starting/running so just not sharing /etc/libvirt is not a solution to the problem/concern...

Ideally if you try to start a VM that is already running on a different host it should balk and you should get an (overridable) warning. (IMHO)

Well don't share /etc/libvirt, there is no need to.

Just have the domain config on the host that currently executes the
domain and tell libvirt to migrate the persistent domain condif along
with the domain:

virsh migrate --persistent --undefinesource vm1 qemu://virt2/system

I suppose that would work... but if Virt2 dies and I need to start its VMs on Virt1 those XML configs won't be there and it will make it more complicated.

Not just a simple "virsh start Foobar"
