Hello all,

I want to experiment with LTSP, so I've created two VMs: one has the LTSP server installed on it, and the other is fresh VM with no disk. The two server VM has a NAT interface and an Internal interface, and the client has just an Internal interface, connected to the same network name.

If I try to PXE boot the diskless VM it just sits there, and a tcpdump on the internal-network interface of the server shows no evidence of the client even trying to reach the server. However, if I boot it from an Ubuntu Live CD, it gets DHCP from the server and everything is fine, so I'm pretty sure it's not a problem with the server (even if PXE was misconfigured, I should still at least be seeing some traffic).

Does anyone have an idea what might be going on? I notice that the docs say "PXE booting is now supported in NAT mode"... that doesn't mean only in NAT mode, does it? (in any case, I've tried it with all adapters set to NAT, and nothing's changed).

Advice?

Did you install the Extension Pack?

If you mean the Devices->Install Guest Additions thing, the server does have that, but it doesn't seem that I can install it for the diskless client. Since that's at the OS level, it couldn't be needed for PXE boot though anyway, at least on the client, right?

If he'd meant that, he would have said Guest Additions The Extension Pack is something else and is installed on the host, not in a VM.

See https://www.virtualbox.org/wiki/Downloads for download and licensing conditions of the Extension Pack.

Heh, sorry, should have done a search before assuming.

Well, that fixed it. Thanks!
