Hi Stuart,
thank you for looking at the topic.
Here is the boot log, and the install.conf.
In the log, line 19, IPv4 nameservers are used,
but we define in the install.conf line 12 a IPv6 nameserver.
This IPv6 nameserver is ignored and will not be added to /etc/resolv.conf
### install log
1 (I)nstall, (U)pgrade, (A)utoinstall or (S)hell?
2 Could not determine auto mode.
3 Response file location? [http://xxx.xxx.xxx.1/install.conf]
4 Fetching http://xxx.xxx.xxx.1/install.conf

6 Terminal type? [vt220] vt220

8
9 Available network interfaces are: vio0 vlan0.
10 Which network interface do you wish to configure? (or 'done')
[vio0] vio0
11 IPv4 address for vio0? (or 'autoconf' or 'none') [autoconf] none
12 IPv6 address for vio0? (or 'autoconf' or 'none') [none]
yyy.yyy.yyy:2830:1::aa
13 IPv6 prefix length for vio0? [64] 64
14 Available network interfaces are: vio0 vlan0.

[done] done
16 IPv6 default router? yyy.yyy.yyy:2830::1
17 add net default: gateway yyy.yyy.yyy:2830::1

22 Public ssh key for root account? [none] none

27 Which speed should com0 use? (or 'done') [115200] 115200
28 Setup a user? (enter a lower-case loginname, or 'no') [no] no
29 Since no user was setup, root logins via sshd(8) might be useful.
30 WARNING: root is targeted by password guessing attacks, pubkeys
are safer.
31 Allow root ssh login? (yes, no, prohibit-password) [no] yes

Hi,
for our OpenBSD PXE/autoinstall environment we are using a IPv4 PXE
server and a OpenBSD mirror with IPv6 address. Since OpenBSD 7.2 we have
an issue with the nameservers during the autoinstall process. (OpenBSD
6.9, 7.0 and 7.1 work fine)
If we start a VM to install OpenBSD 7.2 via PXE it gets an IPv4 address
via dhcp, loads the ramdisk bsd.rd and loads the install.conf file
successfully. Than it loads the install.conf file, where we define a
IPv6 IP, IPv6 Route and IPv6 nameserver server:
Choose your keyboard layout = de
System hostname = test-openbsd-autoinst
Which network interface do you wish to configure = vio0
IPv4 address for vio0 = none
interesting, so you tell it not to use v4 here, but...
nameserver yy.yy.yy.1 # resolvd: vio0
nameserver yy.yy.yy.2 # resolvd: vio0
can you show more (ideally all) of the log?
