Public bug reported:
qemu-system-x86 looses network connectivity even at low loads. Using qemu
running VM with
- FreeBSD 11, 12, 13, 14
- Ubuntu 20.04, 20.10, 21.04, 21.10, 22.04(beta)
- Fedora 34, 35, rawhide
- debian stable, testing, unstable, debian-kfreebsd, debian-hurd
- gentoo
- haiku
- OpenBSD 6.9, 7.0
- NetBSD 9, 10
- kali
- OpenIndiana
- openSUSE leap, tumbleweed
After starting a simple task like updating the VMs system with
- apt update; apt upgrade; apt full-upgrade
- zypper update; zypper upgrade
- dup upgrade
The established ssh-session gets lost and it is not possible to
establish it again. The further running VM does not act on ping -- it
does not even receive the icmp echo request. Seems the bridge is the
problem. The VM looses connection to the virtual bridge and it is
impossible to reenable it.
