Sorry that nobody commented to this ticket in the past... Anyway: The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or please mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1815252 Title: virtio-9p-pci passthrough fsync hang Status in QEMU: Incomplete Bug description: Tested against QEMU: e47f81b617684c4546af286d307b69014a83538a and $qemu-system-x86_64 --version QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.9) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers + exec sudo qemu-system-x86_64 -enable-kvm -bios /usr/share/ovmf/OVMF.fd -cpu host -smp sockets=1,cpus=4,cores=2 -m 2048 -vga none -nographic -chardev socket,id=chrtpm0,path=/tmp/clrwifi/swtpm2/tpm-sock -tpmdev emulator,id=tpm0,chardev=chrtpm0 -device tpm-tis,tpmdev=tpm0 -device virtio-rng-pci -netdev user,id=mynet0,hostfwd=tcp::10022-:22 -device virtio-net-pci,netdev=mynet0 -kernel /home/.../Documents/c/iwd/tools/bzImage -append 'console=ttyS0,115200n8 quiet kvm-intel.nested=1 init=/usr/bin/bash initcall_debug tsc=reliable no_timer_check noreplace-smp cryptomgr.notests rootfstype=9p root=/dev/root rootflags=trans=virtio,version=9p2000.u rw' -fsdev local,id=fsdev-root,path=mnt,security_model=passthrough -device virtio-9p-pci,fsdev=fsdev-root,mount_tag=/dev/root [ 0.000000] Linux version 4.19.0-rc2 (...)
