Wink Network for vmm virtual machines?

Hi,

Can anyone guide me to configure a network for vmm virtual machines on OpenBSD 6.2? I have been trying to configure it for days, and I have not succeeded.

I used this guide by @jggimi a while ago but I'm not sure how much has changed since then:

http://daemonforums.org/showthread.php?t=10001

There is also the ever-reliable FAQ:

https://www.openbsd.org/faq/faq6.html#VMMnet

Also, if you detail exactly what you have tried so far then that will prevent duplication of effort by any who try to help.

This is what I have tried:

Put this line in /etc/sysctl.conf:
Quote:
net.inet.ip.forwarding=1
Put this line in /etc/pf.conf:
Quote:
match out on egress from !(egress) nat-to (egress)
Put this line in /etc/hostname.vether0:
Quote:
inet 10.9.0.1/24
Reboot

Run the following commands:
Quote:
vmctl create disk.drive -s 10g
sudo vmctl start install -c -b /bsd.rd -d disk.drive -i 1 -m 1g
After choosing (I)nstall on the virtual machine, I run this command on the host machine:
Quote:
sudo ifconfig bridge0 add vether0 add tap0 up
Back to the virtual machine, I set the vio0 network interface as 10.9.0.2, netmask 255.255.255.0, default IPv4 route 10.9.0.1, DNS server 10.9.0.1, but the virtual machine could not reach the internet:
Quote:
Let's install the sets!
Location of sets? (disk http or 'done') [http]
HTTP proxy URL? (e.g. 'http://proxy:8080', or 'none') [none]
HTTP Server? (hostname, list#, 'done' or '?') [openbsd.hk]
Server directory? [pub/OpenBSD/6.2/amd64]
Unable to connect using https. Use http instead? [no]

A lot has changed. That "How To" is missing a year of major developments and is somewhat out-of-date.

For networking, the biggest change has been the addition of local interfaces. See the -L option and the LOCAL INTERFACES section of the vmctl(8) man page.

This appears to be a reasonable set of provisioning steps. I'll guess your issue is caused by something you have not reported, such as the rest of your PF rule set. If you have a default block rule set, you must explicitly pass all desired network traffic for your host and guests.

My pf.conf file contains only that line.

Then you have a default pass rule set. So PF is not the source of the problem. I'm not out of guesses, though. My second guess: Are you running a DNS server on your host? If not, then you've misconfigured your guest's domain name server address.

---

Local interfaces can simplify running vmm(4) guests. Once they became available I switched to using them exclusively for all of my guests. With a local interface, there is no need for a bridge(4), no need for any vether(4) device, and no need for static networking on guests. See my comments in my first post above regarding where to learn about this feature.
