راه اندازی شبکه guest با libvirt در حالت bridge

اول اینکه تنظیمات پیشفرض را پاک می کنیم

If he leaves it in a NAT format where there's DHCP, he has to NAT through iptables. The host has to have ip forwarding turned on in /etc/sysctl.conf.

If he destroys the default virbr0, he can attach the vm to the bridge created with the physical interface on the machine. Thus, he'll get DHCP from another source and can get out, without having to deal with NAT and iptables from the host.

, I destroy the initial virbr0 interface. I don't want to deal with another NAT when I have another router that does it already 

me: how can i destroys the default virbr0 and attach the vm to the bridge created with the physical interface on the machine?

virsh net-undefine default

service libvirtd restart

That's how you destroy the initial interface virbr0

I too don't need the virbr interface, everything is through the br0

If you have virt-manager at your disposal, you'd open the virtual machine, click details, click your NIC, and set the source device to the bridge that's available.

حالا برنامه virt manager 

را باز می کنیم در و از قسمت تنظیمات 

guest 

از بخش

nic روی 

vnet0(Bridge brr0)

را انتخاب می کنیم.

 یا اینکه

virsh attach-interface debian_serv bridge brr0 vnet0

me: what about net config on guest?

COnfigure it on the guest according to what your network operator wants.

If there's no DHCP, it needs a static address according to your network.
