LXD 4.20 supports live migration of LXC containers

LXD now has live migration. Perhaps recently the CRIUgenic technology has advanced a bit and Proxmox can start looking into this as well?

That live migration is for VMs (not for containers).

Late to the party, but interested in the subject.

According to https://blog.ordix.de/live-migration-von-linux-containern-mit-lxd it is about containers and not about VMs. Is the linked blog post misleading, or did something change?

Any update on this? Anyone look into it more? Would be nice to have live migration for LXC. Based on the article it is working as long as you add: CRIU and LXD.

I'm definitely interested in the developments here, too! The inability to perform live migrations is one of the only disadvantages of CTs vs VMs in Proxmox.

Wht you gain on the swings, you loose on the merry-go-round.

One of the "pains" that OpenVZ never made it into the kernel ;(

I am interested in the development in here as well. Live migration is the foundation for highly available LXC container instances.

Seems this will never happen. Been this long and no response from Proxmox. Maybe lxc is on the way out and we just don't know it yet.

There just isn't anything for ProxMox to respond about: LXCs doesn't and isn't expecting the get live migrations, it'll only be the Qemu/KVM VMs.

PS: Does K8s supply live migrations? using which container tech?
