Hi, I have send some patches last week to pve-devel mailing to do simple mass live migrate from one node to another node.
It's not yet added to proxmox git. ----- Mail original ----- De: "Gilles Mocellin" <[email protected]> À: "Jonathan Schaeffer" <[email protected]> Cc: [email protected] Envoyé: Mercredi 20 Mars 2013 12:31:43 Objet: Re: [PVE-User] Massive live migrations Hello, I want that since the beginning. XEN Center has it, I think VMware too... There is two problems to solve to be right : - Where migrating the VMs (this should work even without HA set up) - Remember where the VMs were, to migrate them back after the node come back That's why I thing it is not so simple. What I personally do, is a "for" loop on the node I want to bring down. For example : List the running VMs (and keep it somewhere to bring them back) : # vzlist CTID NPROC STATUS IP_ADDR HOSTNAME 100 35 running 172.20.1.157 vmlxcap024.xxx 101 72 running 172.20.1.163 vmlxcap030.xxx # qm list ... (I don't have kvm VMs) # for vm in 100 101; do vzmigrate --live node2 $vm; done # for vm in 101 102; do qm migrate -online $vm node3 ; done Something like that.
