#copyfail is why the Forgejo Actions runner service i'm setting up will be using kvm and single shot VMs rather than containers
-
@whitequark copy-on-write shallow clones of VMs works great for CI. I was doing it back in 2011 or so.
@thejpster yep, the plan is to do something like that with microVMs (or the closest approximation if the obvious solution is non-viable)

@whitequark containers: the convenience of a VM and the security of rawdogging userspace

@whitequark dunno what copyfail is but we're gonna end up doing the same
currently working on migration to our alpine+libvirt+scripts hypervisor os on main server specifically to allow for stuff like this
eventually plan to make a thing to let us do docker compose style services, but as a full VM per service or a container runtime if required -

@whitequark I suspect you won't be using VMware vSphere and the VMware Perl SDK though

@janl yes (already underway) and uh want to buy me a motherboard?
@whitequark I have my old box collecting dust while waiting for a crazy enough buyer. Im slowly lowering price, but probably it’s not going to be sold in next few months.
If it’s any use for you in meantime, I can give you direct access to bcm webui so you can do whatever you like with it
We can figure out how much of heads up you need in case someone would be willing to buy it. And I have second low power box that can be used for backups

while we'd love to use xcp-ng, the old kernel / xen kinda limits its use on little guys (fucked cpu freq scaling), and proxmox requires so much host configuration for our weird setups which we'd rather avoid, so making our own embedded style alpine distro with A/B boot specifically for this -

@thejpster mercifully, no

@alex access would help a lot for testing, yeah!

@whitequark let us know how you get on with em
we did some hacking on crosvm and used it a while ago but knowledge gained never sync'd -

@whitequark Wow... that one is pretty bad.
Guess I'm deleting some kernel modules today.

@thejpster i have to say Solaris zones are surprisingly slow for this

@whitequark awesome! Gimme some time, I'll prepare everything. How can I reach you to hand over access credentials?

@alex whitequark@whitequark.org, you can encrypt to https://codeberg.org/whitequark.keys

@whitequark wanna tell me a bit more about that forgejo runner system?
interested. -

@whitequark What do you use the orchestrate the VMs? Every time I try to do this I end up trying to reinvent half of libvirt.

@ananas nothing specific yet, trying out some stuff
