Hi All, I have analysed my code and added the usb configuration while spawning the guest CMM. Unfortunately still the usb is not visible. Could you please help me on this. I added this config "-usb -usbdevice host:090c:1000 " . you can see in the last but one line Following is my config
/bin/qemu-system-x86_64 -aos cmm -smp 2 -m 3072 -aosimage /flash/working/Mos.img -device virtio-prestera --enable-kvm -machine accel=kvm -qmp tcp:127.0.0.1:11364,server,nowait -netdev type=tap,id=eth0,ifname=tun0cmm,script=no,downscript=no -device virtio-net-pci,netdev=eth0,mac=2c:fa:a2:0a:29:46 -netdev type=tap,id=eth1,ifname=tun1cmm,script=no,downscript=no -device virtio-net-pci,netdev=eth1,mac=00:0a:1e:11:11:f8 -netdev type=tap,id=eth2,ifname=tun2cmm,script=no,downscript=no -device virtio-net-pci,netdev=eth2 -netdev type=tap,id=eth3,ifname=tun3cmm,script=no,downscript=no -device virtio-net-pci,netdev=eth3,mac=00:0a:1e:11:11:f8 -netdev type=tap,id=eth4,ifname=tun4cmm,script=no,downscript=no -device virtio-net-pci,netdev=eth4 -nographic -pidfile /CMMGuestPid -append -usb -usbdevice host:090c:1000 "console=ttyS0 empipaddr=172.17.2.189 empnetmask=255.255.255.0 empgateway=172.17.2.254 medora_early.ALU_VMSlotNum=0 medora_early.ALU_VMPrimaryA=1 medora_early.ALU_VMIsCmm=1" Have few questions please clarify. 1. Is it possible to add usb configuration once the guest is UP. That is dynamically adding the usb configuration 2. Once the configuration is done, should I unplug and plug the usb flash stick (pendrive) 3. does lsusb show usb devices at guest also Regards, Girish -----Original Message----- From: Stefan Hajnoczi [mailto:stefa...@gmail.com] Sent: Wednesday, September 28, 2016 1:56 PM To: Kumar Girish Cc: qemu-devel@nongnu.org Subject: Re: [Qemu-devel] external usb flash drive support on qemu virtualization On Mon, Sep 26, 2016 at 03:25:26PM +0000, Kumar Girish wrote: > I am new to virtualization on Linux.

But same is not visible at guest VM. The guest hardware is independent of the host hardware. Devices plugged into the host do not automatically appear inside the guest. How to make the flash drive available to the guest depends on how you are using QEMU. Are you using a management tool like virt-manager or virsh? virt-manager has a graphical user interface for passing USB devices into the guest. Go to Details | Add Hardware | USB Host Device. Stefan
