Hello, I have been using successfully Dovecot 1.1.x for about a year now. It has been very stable. Now I'm uprading that same system to newer and more powerful hardware and I was wondering whether it is good idea or not to switch to Dovecot 1.2.x series. Could anybody direct me to feature comparision document or explain here main differences betweeen thos two branches? -- Veiko

Hello, Upgraded from 1.2.x to 2.0.5, converted configuration as described in http://wiki2.dovecot.org/Upgrading/2.0 and now I'm unable to log in to imap server.

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

I am having trouble with recovery. Today due to electrical work I powered down my networks Router / DHCP server. My Centos 7 host machines lost their DHCP lease (they are actually static leases). Once I power my Router / DHCP server back up none of my virtual machine were accessible. It appears that when the DHCP lease was lost on the virt server the bridge of the KVM guest were all losts. A

Hi, I have tried the qemu-ifup script as below with nmcli command as brctl is deprecated on rhel8, but the guest network can not work. I think the script needs update. Could you please help to have a look? Thank you in advance. 1. prepare a linux bridge on the host named br0; 2. prepare the qemu-ifup script as below: # cat /etc/qemu-ifup #!/bin/bash # A br0 bridge should be already set up. #

Hello, I am facing some problems in bridged networking. I have successfully created a bridge br0 and added a virtual machine to it. Now the address of virtual machine is 10.1.3.31. I am able to connect to this virtual machine by another computer on same network. The virtual machine is hosting a simple python http server on port 8000, while some other service is running on port 80 When I try

I should have what i want to achive. The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host

Hi, I have an fc14 install and would like to install a few kvm guests but am having difficulty with the networking. On the host I have disabled NetworkManager and configured a bridge which has eth0, the only physical interface on the server. I have a dhcp server on the local lan, and if I add a mac address entry to my dhcpd.conf, the guest will find an IP from there. I think somehow the guest

Hi all, I'm observing an issue that as soon as libvirt starts, UPD broadcasts going through physical network (and unrelated to any virtualization) get broken. Specifically, windows neighbourhood browsing through samba's nmbd starts suffering badly (Samba is running on this same box). At the moment I'm running a quite outdated version 1.2.9 of libvirt, but other than this issue,

someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work.
