LXD uses QEMU/KVM/libvirt for VMs thus the performance is at least the same as any other QEMU solution like Proxmox, the real difference is that LXD has a much smaller footprint, doesn’t depend on 400+ daemons thus boots and runs management operations much faster. The virtualization tech is the same and the virtualization performance is the same.
Maybe I’m just doing it wrong. I’ve just found LXD to be lacking as you can’t live transfer it to a different host. It is also slower than Docker and Podman and I was unable to get docker running in a unprivileged LXC container. I think it should be possible to run docker in LXC but by the time I spend the effort is is more secure and easier to use a full virtual machine.
Maybe I should revisit the idea though as it seems like many people stand by it.

Sorry I meant high availability as in the ability to live transfer a VM to a different host without downtime or service interruptions.
Oh, my bad then. But yes, like Proxmox, LXD/Incus can do live migrations of VMs since 4.20 (2021 I believe). Live migration of containers can be done under specific circunstantes as well.
Are you using a container runtime in the LXC container? (i.e. docker or podman)
In some of them yes. At least under Debian as long as you’ve set security.nesting=true it will work fine.
i looked it up, and it’s part of vmware? i don’t run that so *shrug*
*proxmox*
*LXD/Incus*
LXD is not really usable for anything as it is very slow

It isn’t lacking… https://linuxcontainers.org/incus/docs/main/howto/move_instances/#move-instances but as with Proxmox there are details when it comes to containers. VMs can fully migrate live.
What host OS are you running on? Did you set
security.nesting trueon said container?I probably just set it up wrong.
oh, fuck. really? what if i have 12 year old copy?
I meant you should switch to proxmox. What are you referring to?
No this is Patrick.
He should really switch to LXD/Incus, not Proxmox as it will end like ESXi one day.
Lxd is slow and doesn’t support HA

Here’s one of my older LXD nodes running HA:
It’s “so hard” to run HA under LXD… you just have to download the official HA OS image and import to LXD.
