I am suspicious upstream commit e7a409c3f46cb0dbc7bfd4f6f9421d53e92614a5
("ipv4: fix IPSKB_FRAG_PMTU handling with fragmentation") might fix
this. It has been queued in eoan tree as part of 5.3.10 update.-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1849720 Title: KVM with e1000e and WinGuest Host OS on kernel 5.3 (ok with 5.0) Status in linux package in Ubuntu: Confirmed Status in qemu package in Ubuntu: In Progress Bug description: After upgrading to Ubuntu 19.10 I noticed that all of my Windows Servers VMs would cause a hard crash on the Host OS shortly after starting up the VM. I tracked it down to the Guest OS attempting to use the Network Connection, and if I disabled the virtual NIC for the VM, everything runs OK (albeit without a working network connection for the Guest OS). Note that I'm just using the built in virtual network called "default" that get's installed by default and uses NAT forwarding. I believe the problem is related to AppArmor, as I noticed some errors present in various log files. Unfortunately, due to a time critical project I had to roll back to Ubuntu 19.04 and didn't capture any of the log files. I did, however, find another user on Reddit with the exact same problems that I encountered and he agreed to let me post the log files. Here are what are think are the relevant pieces from the log files: =================================================================== Oct 22 22:59:23 brian-pc dnsmasq[2178]: exiting on receipt of SIGTERM Oct 22 22:59:23 brian-pc kernel: [ 67.001284] device virbr0-nic left promiscuous mode Oct 22 22:59:23 brian-pc kernel: [ 67.001298] virbr0: port 1(virbr0-nic) entered disabled state Oct 22 22:59:23 brian-pc NetworkManager[3557]: <info> [1571799563.3862] device (virbr0-nic): released from master device virbr0 Oct 22 22:59:23 brian-pc gnome-shell[4401]: Removing a network device that was not added Oct 22 22:59:23 brian-pc gnome-shell[2463]: Removing a network device that was not added Oct 22 22:59:23 brian-pc avahi-daemon[1621]: Interface virbr0.IPv4 no longer relevant for mDNS.
