Hi All, I have a problem may about Qemu and kindly need your help. Does qemu-system-aarch64 support virtio-9p ? Recently I have tried to use qemu remapped the file from host to guest. As I know, Qemu has supported this so long as guest kernel has support 9p(virtfs). Reference to this link: http://wiki.qemu.org/Documentation/9psetup Fedora 24 AArch64 kernel has supported this: [root@sha-win-225 ~]# lsmod | grep 9p 9p 56273 0 fscache 87449 1 9p 9pnet_virtio 9122 0 9pnet 83564 2 9p,9pnet_virtio virtio_ring 13866 5 virtio_net,virtio_pci,9pnet_ virtio,virtio_mmio,virtio_scsi virtio 9467 5 virtio_net,virtio_pci,9pnet_ virtio,virtio_mmio,virtio_scsi
Now I use virsh to launch the VM, and the corresponding qemu command I have pasted here: http://paste.openstack.org/show/549225/. You can see that: * -fsdev local,security_model=mapped,id=fsdev-fs0,path=/var/lib/libvirt/images/coreos -device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=share,bus=pci.2,addr=0x1* Here is the command that remapped the directory from host to guest. After VM launched, I use the command to mount: * mount -t 9p -o trans=virtio share /tmp/shared/ -oversion=9p2000.L,posixacl,cache=loose* But mount command will be blocked and output nothing. The Qemu version is QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.2). Besides test fedora24 guest, I have got the same problem in Debian jessie. Kindly need your help~You will be really appreciated. Best Regards, Kevin Zhao
