Thanks Christian for your response. - Yes, the guests are connected to a software bridge (br0) created on top of host physical NIC interface and they are getting DHCP IP addresses from external DHCP server.
- So far, we have seen this issue a couple of times and only way to recover is to reboot the host system. This indicates, it is something to do with the linux bridge configuration or driver. If it is a DHCP server, the issue should persist across reboot too. - One another data point is that, we don't see this issue if we use "MacVTap configuration" for guests, each of them gets DHCP IP address and no issue of losing IP address. This indicates this issue is something specific to linux bridge (br0) setup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817998 Title: KVM Guest - DHCP lease lost (Ubuntu 18.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1817998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
