can i get console on it?

it looks odd

1) networking appears to be broken, times out a lot, and fails to resolve URLs and connect to them

2) disk probing appears to time out, which is odd too.

One thing that maybe different about this test vs. our other ARM
server tests is that this server is in a lab behind a proxy.

The boot media is a virtual DVD emulated by a BMC java applet running
across a VPN. This obviously adds latency, not sure if it would be the
timeout source.

Why don't you netboot instead of using DVD?

1) extract initrd & linux from the .iso

2) boot using cmdline:

ip=dhcp url=http://url-to-the-iso/that/matches/initrd/linux/filename.iso

.... or any other netbooty way (ie. uefi secureboot http boot etc)

We created a set of test cases with mixed platform/boot method
combinations, and this one was a DVD one.

Can you run subiquity.probert in a shell and see if it completed slowly or
is really hanging?

Upon retrying, I'm unable to reproduce. At a shell, subiquity.probert took ~5s.

Well the default timeout is 5s. I guess we should increase that a bit!

I increased the probe timeout to 15s for other reasons, so I think this should be fixed now. Please reopen if it's still a problem!
