Supported Dynamips and Cisco IOL images
Short version: if you're wondering whether your Dynamips or Cisco IOL image will actually work in netplex., this page has the answer for the specific file you're holding, not a general "should be fine." We booted every one of these, wired it into a real lab, and pinged across the link - see the write-up for how we ran the campaign, or jump straight to importing a Dynamips image / importing an IOL image if you already know what you need.
How we tested
Every image below was imported the normal way through the Library, dragged onto a canvas, powered on, and reached over an actual netplex. link - not just booted in isolation. A "working" result means a real ping got a reply across that link. When one didn't behave as expected we didn't just write it off: we checked the interface's own packet counters and tried a self-ping on the box itself, to work out whether the problem was ours or the image's.
Dynamips - 23 images, all working
Every Dynamips platform we had came up clean across every build we had for it - full CLI, routing, and a successful ping every time:

Cisco IOL - full routers
These three run as complete routers, nothing to flag:

Cisco IOL - full switch and router
Both builds below do everything the router-only images do, plus real Layer 2 switching - confirmed with a plain interface Vlan1 and a ping across the switched segment:
L2-ADVENTERPRISEK9-M15.2L2-ADVENTERPRISEK9-M15.2-IRON
Cisco IOL - routers only (switching doesn't reach the SVI)
These five boot and route just fine, but a standard switchport-to-SVI setup never forwards traffic. We didn't stop at "doesn't work" - the interface's packet counters showed frames arriving, and a self-ping proved the IP stack itself was healthy. What's missing is the internal hop from the switchport into interface Vlan1; it just never happens in this image family. netplex.'s OVS (the virtual switch it uses) wiring and TAP interfaces (virtual network ports) checked out fine the whole way through, so the problem is inside the image, not netplex.

Workaround: skip the switchport, configure the interface as routed instead:
interface Ethernet0/0 no switchport ip address <address> <mask>
Do that and all five ping cleanly and work as routers, no other changes needed.
Not supported
C7200 - 7 images, excluded. Not a netplex. problem: Dynamips itself never added support for the NPE-G1/NPE-G2 hardware (router parts) these images need, so they can not run on any platform.

2 list entries with no file behind them, excluded. These are placeholders with no real image file (iol-xe-17-12-01 and ioll2-xe-17-12-01) - there was nothing to import, let alone test.
If your exact image isn't listed above, it's untested rather than unsupported - most Dynamips-supported platforms and IOL builds we haven't explicitly run should still work, this list just reflects what we've personally confirmed with a real ping. Found one that behaves differently from what's written here? Let us know and we'll add it to the next pass.
