getting iohyve VM to access the network

[nicosalto]

Hi,
i am having trouble to get my debian iohyve VM to connect to my local network.
My goal is to install a roon core server, and i am following this tutorial: https://community.roonlabs.com/t/howto-debian-installation-on-frenas-bhyve/10591

My current configuration is :
FreeNAS-11.1-U2 - X11SSM-F supermicro - 2x16Gb kinston - 4x4Tb WD drives + 2x2Tb drives
my motherboard is a Supermicro X10SL7-F and according to the manual, this is the lan interface:
2x RJ45 Gigabit Ethernet LAN ports
1x RJ45 Dedicated IPMI LAN port
https://www.supermicro.com/products/motherboard/xeon/c220/x10sl7-f.cfm

And this is my ifconfig

Iam not very familiar with this output and how to read it properly.
according to the tutorial i need to setup this line in the tunables to setup the network bridge. In my case i don't have an interface named em0, so which one i must use ?
iohyve_flags="kmod=1 net=em0"

similar question for this line
iohyve setup net=em0
In my case which interface i should point iohyve to?

Lastly, within the debian VM, this the current configuration i am using:
/etc/network/interfaces

# The loopback network interface
auto lo0
#iface lo0 inet loopback

#My IP description
#IPv4 address
auto enp0s3
iface enp0s3 inet static
address 192.168.1.100
netmask 255.255.255.0
#network 192.168.1.0
#broadcast 192.168.1.255
gateway 192.168.1.1



# ip a show

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet6 ::1/128 scope host

link/ether 00:a0:98:ba:de:1f brd ff:ff:ff:ff:ff:ff
inet 192.168.1.100/24 brd 192.168.1.255 scope global enp0s3
valid_lft forever preferred_lft forever
inet6 fe80::2a0:98ff:feba:de1f/64 scope link
valid_lft forever preferred_lft forever


Any advice is most welcomed! thanks in advance!

UPDATE:
i solved partly the issue! i changed
iohyve_flags="kmod=1 net=em0"

to
iohyve_flags="kmod=1 net=igb1"
restarted freenas, and now i can ping the roon core server from my local network.
BUT, VM doesnt access internet. It fails when i do apt-get update.
Could it be a dns issue ?

 

[KrisBee]

From the output of ifconfig that you posted, the active interface is "igb1" at "192.168.1.5". So I'd expected you'd access your FreeNAS webUI using ip address "192.168.1.5" and can use the network tab to confirm that is the active interface. If so, substitute "igb1" for "em0".

Crossed post:

Just check network config in your vm. What are the contents of /etc/resolv.conf ? Could be you need to add this line to etc/network/interfaces

Code:

dns-nameservers 192.168.1.1

Assuming your router is at 192.168.1.1 and it is acting as your DNS.

 

[nicosalto]

Thanks for your answer KrisBee.
yes the active interface of igb1 is 192.168.1.5 and i access the freenas web interface via that address.
But when i put em0 instead of igb1, then the VM can't access the network at all. At least when i use igb1 i can access the server on my local network.
I added the line of code to /etc/network/interfaces as you recommended, but it doesnt change anything.
Also the file /etc/resolv.conf is empty on the VM machine, what should it contain ?

 

[nicosalto]

It is a DNS issue i think, i edited /etc/resolv.conf and added:
nameserver 38.132.106.139
nameserver 194.187.251.67

and now “ping 8.8.8.8” within the VM works!
But when i “ping google.com”, i get the error:
ping: google.com: Name or service not known

 

[KrisBee]

Adding a dns-nameserver line to the config for the vm interface enp0s3 you posted above, should have enabled you to "ping" external ip addresses. Did you restart the network service after making the change and/or re-boot your vm?

As an alternative, remove the line you added and simply add a nameserver entry to /etc/resolv.conf, as root

echo "nameserver 192.168.1.1 > /etc/resolv.conf

Test you can ping out and go form there ....

 

[nicosalto]

Yes thanks KrisBee, this actually solved the issue!

But, every time i restart the VM the file goes empty.
and if i had to it:
nameserver 192.168.1.1
then everything works again …
