[SOLVED] usb with qemu-kvm on Slackware 13.1

2handband · 12-26-2010, 06:19 AM

I don't know how much experience anyone here has with qemu-kvm, but I'm trying to get it to talk to my USB mouse. Here's the command:

Code:

gene@bruce:~/.qemu-kvm$ qemu-system-x86_64 -hda vms/ubuntu_disk.img -m 1024 -net user -net nic,model=e1000 -vga std -cdrom /home/gene/.qemu-kvm/ubuntu-10.10-desktop-amd64.iso -boot d -usbdevice host:046d:c50e

And here is what I get:

Code:

husb: open device 4.2
/dev/bus/usb/004/002: Permission denied

Any ideas?

I use the same USB mouse for my standard desktop and it activates for any KVM desktops. Normally I just use the "-usb" command option.

When I use other USB devices like flash drives I get a similar permission response as you got. If that's the case, as root, my notes are "chown -R my_user:root /proc/bus/usb" Then I switch to the KVM monitor method of access and run "info usbhost" to get the mac address then use that mac address "usb_add host:mac1:mac2" in the monitor.

What's this KVM monitor thing?

Problem solved by running the command with -usbdevice tablet.

I used the wrong term. It's actually the QEMU monitor thing.
