[libvirt-users] qemu:///session and network-mounted home directories

Dear libvirt-users, Suppose my home directory is network mounted on to several different machines. And suppose I defined some VMs in qemu:///session. The configuration files and disk images for qemu:///session are stored in my home directory. Now suppose I log in to some machine and use virsh. The qemu:///session VMs that are marked autostart are started. Now if I log into another machine and use virsh, it will presumably try to start my autostart VMs again, since the same configuration is present in both homedirs. Is there anything libvirt does that might prevent it from starting the same VM multiple times on different machines? Or might allow machine-specific autostart configuration? Maybe something could be done with /etc/machine-id! In terms of qemu:///system, this is like having /var/lib/libvirt/images/ live on a network-mounted filesystem (fairly normal I assume) and also having /etc/libvirt/qemu live on a network-mounted filesystem (not as normal). Not sure how you would deal with the issue there either but I can see why you might want to have your same VM configuration available on all hosts, so it would be cool to figure out that problem as well. The answer may be the VM configuration is host-specific, so sharing VM configuration between hosts is not a good idea. In that case, any other recommendations on how to deal with the networked homedir case? Thanks!
