A devuan wiki page on virt-manager

chomwitt · 2024-03-15 09:24:26

---- UPDATE ---
I stopped the wiki page on virt-manager and instead i started a new one
on using Qemu in CommandLineInterface. Using QEMU from a CLI
---- endupdate ---

I started a wiki page on virt-manager in the https://wiki.devuan.org

It's in the sandbox in https://wiki.devuan.org/Sandbox/Virt-Manager .

I occasionaly use virt-manager and in now as in the past i had again difficulties in setting
it right in devuan. So i think a wiki page could function as focus in order to collect
instructions and tips to smooth things out.

devuan wiki needs i guess some thinking about how to organize things so for
time being i put it in the sandbox.

Also for now i choosed to use as name the package name that i used for installation.

Any corrections and suggestions are welcomed .

Hello.

For better experience, i use these packages:

qemu-kvm libvirt-clients libvirt-daemon libvirt-daemon-system bridge-utils virtinst virt-manager

Also, don't forget to add your user to libvirt and libvirt-qemu groups:

adduser username libvirt
adduser username libvirt-qemu

qemu-kvm is no part of Daedalus.

I'm sorry. An error occurred. I wanted to write

qemu-system-misc

stopAI thanks for the suggestion. Searching recursively in virt-manager dependencies ... ->

$ apt-cache depends --recurse --no-suggests --no-conflicts --no-breaks --no-replaces --no-enhances virt-manager | grep "^\w" | sort -u | grep 'virtinst\|libvirt-clients\|libvirt-daemon\|qemu-system-misc\|bridge'

...-> i see that bridge-utlis is the only that is not pulled.

I have never used virt-manager. I tried using about a year ago, but quickly became annoyed with it and gave up. Since it is unnecessary and I can use QEMU without it, that is my current preference. I only mention that because some people seem to think that using virt-manager is a requirement.

I started using virt-manager and it kind felt ok . But it has that irritating config setup.
I wouldnt have problem trying command line. A small push with a link to a good tutorial
would help. I dont mean fancy one in a website that welcomes you with a thousand cookies
harvester companies. A simple one laying out simple concepts would be ok.

I also use command line and spicy to connect to the console.

To set up a network bridge (all commands assume that the user executing qemu belongs to group kvm and VMs' IP numbers start with 192.168.128.2):

set up qemu-bridge-helper (has to be done once after upgrade):

chgrp kvm /usr/lib/qemu/qemu-bridge-helper
chmod 554 /usr/lib/qemu/qemu-bridge-helper
setcap CAP_NET_ADMIN,CAP_NET_RAW,CAP_NET_BIND_SERVICE=ep /usr/lib/qemu/qemu-bridge-helper

enable bridge at boot:

echo 1 > /proc/sys/net/ipv4/ip_forward
ip link add name brvm type bridge
ip addr add 192.168.128.1/24 dev brvm
ip link set up brvm
iptables -t nat -A POSTROUTING -s 192.168.128.0/24 -o eth+ -j MASQUERADE
iptables -t nat -A POSTROUTING -s 192.168.128.0/24 -o wlan+ -j MASQUERADE

pass this parameter when launching qemu:
-netdev tap,id=eth,br=brvm,helper=/usr/lib/qemu/qemu-bridge-helper

It is also possible to attach dhcpd and/or radvd to brvm for automatic address space management. By changing those ip commands above you may bridge brvm with workstation's ethernet interface and allow attaching VMs directly to the LAN.
