what is the guest OS? Is it running? I didn't see guest side logs but the scenario matches bug 1270717 (In reply to Michal Skrivanek from comment #3) > I didn't see guest side logs but the scenario matches bug 1270717 The RHEL 7.2.z bugzilla is: bug 1279793 Fixed in: kernel-3.10.0-327.2.1.el7 VM is RHEL 7.2 and VM is up when doing actions of add NIC, plug/unplug. This is the bz - when you do those action VM crashes and goes down This is almost certainly the same as bug 1270717 / bug 1279793. Please retry with kernel-3.10.0-327.2.1.el7. Note that this bug can cause crashes in either host or guest, so you'll want to update the kernel in both. This bug do not happen with these new versions on host: kernel 3.10.0-327.2.1.el7.ppc64le (also on guest) and libvirt-1.2.17-13.el7_2.2.ppc64le qemu-2.3.0-31.el7_2.3.ppc64le thanks for confirmation, I'm closing it then as a duplicate of 1270717 *** This bug has been marked as a duplicate of bug 1270717 *** |
Created attachment 1097641 [details] engine, libvirt, vdsm, qemu logs Description of problem: When you try to plug/unplug NIC on VM or add additional vNIC the VM goes down as a connection to qemu process is lost Version-Release number of selected component (if applicable): How reproducible: Takes a bit of time, but if you plug/unplug existing vNIC or add, remove vNIC from VM the VM goes down Steps to Reproduce: 1. Add vNIC to VM 2. Unplug existing vNIC 3. Plug vNIC back 4 Go over above steps several times Actual results: VM goes down with error message: Lost connection with qemu process Expected results: VM should be up and running Additional info:
