 Posted: Sun Aug 05, 2018 1:39 pm Post subject: kvm with virt-manager (no virtual network) |
 |
|
I'm trying to setup kvm with the virt-manager and I don't have a virtual network.
I'm running systemd gnome and systemd shows libvirtd is running.
loaded active running Virtualization daemon
Please throw me a bone if you've got kvm working on gentoo.
I'm stuck on the virtual network part.
I looked at this guide
https://www.linux-kvm.org/page/KvmOnGentoo#Network_setup
| Code: |
Network setup
Bridged
edit /etc/conf.d/net
config_eth0="null" # any any other interfaces you want to bridge
bridge_brkvm="eth0"
config_brkvm="192.168.254.254/24" # the ip of the original eth0, or dhcp
brctl_brkvm="setfd 0
sethello 30
stp off"
cd /etc/init.d
ln -s net.lo net.brkvm
rc-update add net.brkvm default
rc-update del net.eth0 default
|
Then I read this post and noticed the network configuration.
This looks better.
https://www.agix.com.au/install-kvm-qemu-gentoo/
| Code: |
dns_domain_lo="agix.lan"
config_eth0="10.0.0.1/24"
#
#Additions for KVM
#
config_eth1="null"
bridge_br0="eth1"
config_br0="10.0.0.2/24"
brctl_br0="setfd 0
stp off"

cwc,
You need to translate it to systemdspeak.
| Code: | # eth interfaces for firewall
# we don't want them getting IP addresses
# as they are being donated to bridges
config_eth0="null"
config_eth1="null"
config_eth2="null"
config_eth3="null"
config_eth4="null"
bridge_br0="eth1"
# the DMZ
bridge_br1="eth2"
config_br1="192.168.10.254/24"
# wireless
bridge_br2="eth3"
config_br2="192.168.54.254/24"
# protected wired
bridge_br3="eth4"
config_br3="192.168.100.254/24" |
This is all on the host. I've left out the routing things.
When you create your guest in libvirtd, it will show you the bridges to connect the network too.
I have donated real hardware to the bridges but thats not required.
You can route a range of addresses to a bridge with no hardware on the host too. That works.

Neddy,
I added the following to /etc/conf.d/net and virt-manager did not pick up anything.
dns_domain_lo="ciclo.ioe"
config_eth0="192.168.1.7 netmask 255.255.255.0 brd 192.168.1.255"
routes_eth0="default via 192.168.1.1"
config_eth1="null"
config_eth2="null"
bridge_br0="eth1"
--------
I'm running systemd with Gnome.
I'd like to set up my nic as eth0 and bypass the Gnome networkmanager . But I'll need some guidance.
