Hi, 1. Can you please add the full QEMU command line? 2. On which Windows versions do you observe the bug? Thanks, Yan. Full command line: /usr/libexec/qemu-kvm -S -name avocado-vt-vm1 -sandbox off -machine q35 -nodefaults -device VGA,bus=pcie.0,addr=0x1 -device pcie-root-port,id=pcie_root_port_0,slot=2,chassis=2,addr=0x2,bus=pcie.0 -device pcie-root-port,id=pcie_root_port_1,slot=3,chassis=3,addr=0x3,bus=pcie.0 -device pcie-root-port,id=pcie_root_port_2,slot=4,chassis=4,addr=0x4,bus=pcie.0 -chardev socket,id=qmp_id_qmpmonitor1,path=/var/tmp/123,server,nowait -mon chardev=qmp_id_qmpmonitor1,mode=control -chardev socket,id=qmp_id_catch_monitor,path=/var/tmp/123,server,nowait -mon chardev=qmp_id_catch_monitor,mode=control -device pvpanic,ioport=0x505,id=idAwNOdW -chardev socket,id=serial_id_serial0,path=/var/tmp/123,server,nowait -device isa-serial,chardev=serial_id_serial0 -chardev socket,id=seabioslog_id_20181205-071836-9rDqsWyl,path=/var/tmp/123,server,nowait -device isa-debugcon,chardev=seabioslog_id_20181205-071836-9rDqsWyl,iobase=0x402 -device pcie-root-port,id=pcie.0-root-port-5,slot=5,chassis=5,addr=0x5,bus=pcie.0 -device qemu-xhci,id=usb1,bus=pcie.0-root-port-5,addr=0x0 -drive file=/home/win7-32-sp1-virtio-scsi.qcow2,if=none,id=drive-ide0-0-0,format=qcow2,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -device pcie-root-port,id=pcie.0-root-port-7,slot=7,chassis=7,addr=0x7,bus=pcie.0 -device virtio-net-pci,mac=9a:99:9a:9b:9c:9d,id=id5gwWho,netdev=id2eDVCu,bus=pcie.0-root-port-7,addr=0x0,mq=on,vectors=1 -netdev tap,id=id2eDVCu,vhost=on,queues=4 -m 4096 -smp 4,maxcpus=4,cores=2,threads=1,sockets=2 -cpu Broadwell,+kvm_pv_unhalt,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time -drive id=drive_cd1,if=none,snapshot=off,aio=threads,cache=none,media=cdrom,file=/home/kvm_autotest_root/iso/windows/virtio-win-1.9.3-1.el7.iso -device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1 -vnc :9 -rtc base=localtime,clock=host,driftfix=slew -boot order=cdn,once=c,menu=off,strict=off -enable-kvm -monitor stdio I tested on win7-32, win8.1-32 and ws2019, all hit this issue. And tried on pc and q35, both hit this issue. Indeed, the functionality with single MSIX vector is broken by commit https://github.com/virtio-win/kvm-guest-drivers-windows/commit/861e27206ea84abf8d385c21cbe9c631d640df1f As I can see the functionality with 2 vectors is also broken (partially), the adapter in general works, but process the data only on RX interrupts (not on TX interrupt), so may stuck by chance on driver disable.
