Best practice to manage network
Hi,
First, sorry if the topic has already been discussed recently (the only thread I found
related to my problem was created in 2010..)
I have a hypervisor with KVM and LXC installed on a Debian 12, and I'm using libvirt
to create my VM. All my networks are defined in my /etc/network/interfaces.d/* (I'm
using openvswitch with specific options, such as port mirroring/patch/...) , and I'm
configuring the network on my VM XML definition like this :
<interface type='bridge'>
<mac address='52:54:00:ab:c3:d3'/>
<source bridge='prod'/>
<vlan>
<tag id='55'/>
</vlan>
<virtualport type='openvswitch'>
<parameters interfaceid='331d973c-0c5b-4d3c-b2ad-590f908e680d'/>
</virtualport>
<target dev='vnet180'/>
<model type='virtio'/>
<mtu size='9216'/>
<alias name='net1'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x05' function='0x0'/>
</interface>
It is working perfectly, until I'm restarting my network (using ifreload, ifup,
systemctl network restart, ...) - all my VM come unreachable... To make it work again, I
also need to restart libvirtd
Is it still expected to have this behavior ? What would be a better way to configure the
network ?
Thanks in advance
