Thank you for taking the time to report this bug and helping to make Ubuntu better.
There isn't really enough information here for a developer to confirm this issue is a bug, or to begin working on it, so I am marking this bug Incomplete for now. If you can provide exact steps so that a developer can reproduce the original problem, then please add them to this bug and change the status back to New. Especially important here is the reasoning that brought you to conclude that it's qemu at fault, and not the specific network setup of your host system. Thanks! ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1965675 Title: qemu-system looses network connectivity even at low loads To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1965675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
