Tink vs oVirt
oVirt is a KVM management plane. That is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
oVirt runs the guest. Tink answers “why is this VPS sick?”
Accidental sysadmins land on oVirt because a datacenter console looks like ops. Then the volume fills, guest nginx dies, and /ovirt-engine/api/vms still shows Up — no host alarm matched guest fill. A filling /var is a Tink warning; it is not an oVirt job unless you scraped engine events and watched them.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep using oVirt if you already run KVM datacenters. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | oVirt |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — engine-setup, hosts, storage domains, then a guest that still has no mechanic after /ovirt-engine/api/vms stays Up |
| What you get | Working monitoring, diagnosis, and approved fixes | A KVM management plane. Disk fill, guest nginx, Postgres, and certs stay your problem until you SSH in |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Engine VM, hosted-engine HA, and the engineer who owns the box after webadmin still shows Up |
| Hidden costs | None — fully managed | A quiet qcow2 at 2am, a filling volume, and a second tool to tell you the Linux guest is sick while oVirt webadmin still shows Up |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Guest lifecycle and host health. oVirt does not watch a quiet cert or guest auth.log after the VM started |
| Configuration | None after install — heuristics and AI | Data centers, clusters, vdsm, storage domains, and which guest death actually pages you |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | You read /ovirt-engine/api/vms, then SSH in to change the Linux guest the engine already sits under |
| Fix execution | Proposes and executes approved commands with an audit trail | Start and stop guests only — oVirt cannot free guest disk, rotate a cert, or stop SSH brute-force unless you wrote that runbook |
| Alerting | Built-in across 8 channels | Not an oVirt job — engine events plus a separate monitoring tool have to fire |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Not an oVirt job — a green Up VM does not forecast a quiet volume filling up |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — oVirt does not read guest auth.log, journald, or firewall state after the VM started |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Silence if the guest dies after the last API poll — unless you built a separate uptime check |
| Public status page | Shareable URL with 90-day history | None — oVirt has no customer-facing status page for the Linux guest |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — a webadmin recap is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire failed guests into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | webadmin and REST. No mechanic you text when /var filled and the last VM still showed Up |
| Learning curve | None — works after install | Steep — hosted-engine, vdsm, storage domains, and which host failure is the hypervisor vs the running guest |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Teams that already run oVirt datacenters and need a KVM console, not a sick-VPS mechanic |
When oVirt is the right choice
Keep using oVirt when you already want that exact job:
- KVM datacenters — you need engine-setup, hosted-engine, vdsm, and a webadmin inventory, not a mechanic.
- An existing oVirt estate — storage domains, clusters, and isolation matter more than guest nginx, certs, and SSH on a quiet VPS.
- An existing lab or nested setup — guests already start, the engine already ships, and someone owns the hosted-engine HA.
- Hosts that only page on failed guests — you already run engine events and exporters, not a sick-box SSH loop.
The real cost of “just watch /ovirt-engine/api/vms”
oVirt runs guests. A working ops loop for five Linux boxes is not:
- An Up guest still means you SSH in and change the box by hand when it gets sick later
- Guest fill, nginx, certs, and SSH brute-force never appear unless a separate tool scraped those signals and a rule fired
- A filling /var is a Tink disk warning on every scan — oVirt will stay quiet until the next guest process dies
- A single VPS with a dead agent still needs a mechanic, not another webadmin row
For a 5-server team, Tink Mechanic at $45/month is cheaper than an oVirt engine plus the engineer who keeps failed-guest notifications alive, and every scan includes a diagnosis a quiet API poll will not type.
No hypervisor homework. No silent host. One command install.
