FAQ

This section answers common questions about Mesh Hypervisor. For detailed guides, see Usage.

How do I back up the system?

Copy /host0 and keys from the central node via SSH:

scp -r root@<central-ip>:/host0 ./backup/
scp root@<central-ip>:/var/pxen/pxen.repo.rsa ./backup/
scp root@<central-ip>:/var/pxen/pxen.repo.rsa.pub ./backup/

This grabs configs and keys—restore with scp to a new flash drive. See Upgrading the System.

Why IPv6 only for VXLAN?

IPv6 ensures deterministic, collision-free addressing using UUIDs (e.g., genid machine 8). It’s simpler than NAT-heavy IPv4 meshes. See Networking.

What’s the default config?

New nodes boot with /host0/machines/default/ (UUID default) until a matching UUID folder exists in /host0/machines/. Edit it for baseline settings—see Configuring Nodes.

How do I update configs?

Edit /host0/ locally, then upload:

scp -r ./host0 root@<central-ip>:/
mesh system configure

Reboot nodes to apply (mesh node ctl -n ALL "reboot"). See Managing Nodes.

What if a node’s hardware fails?

Boot new hardware, grab its UUID from mesh node info, update the old machine’s UUID file, rebuild APKOVLs, and reboot. See Recovery Procedures.
