Created attachment 360612 [details] XML file for guest VM. Description of problem: USB devices are not recognized by VM even when SELinux boolean values for qemu and virt are true. Version-Release number of selected component (if applicable): kernel-2.6.31-0.125.4.2.rc5.git2.fc12.x86_64 How reproducible: Everytime. This all worked on FE-11 Steps to Reproduce: 1. Plug in USB disk 2. Unmount USB disk from host 3. Launch VM Actual results: No USB drives mounted Expected results: USB drives mounted to VM system Additional info: Using x86_64 FE-12-alpha and FE-11 x86_32 guest. Host maps USB drives OK.
Thanks for the report Anything interesting in /var/log/libvirt/qemu/Fedora-11-Home.log ? This is qemu-kvm-0.10.91-0.5.rc1.fc12 ? Does updating to qemu-kvm-0.10.92-1.fc12 help? dmesg and lsusb -v output from the guest?

Was able to get 12-alpha udpates applied. Here is my current machine. USB disk still not mounted.

Just sent an upstream fix. I will be able to provide a link as soon as qemu mailing list decides to cooperate.
Here's the fix: http://lists.gnu.org/archive/html/qemu-devel/2009-09/msg01198.html
Wait, that fix doesn't appear relevant to the F-12 tree - the that fixes looks like it was introduced by the qdev conversion
Okay, I found one issue with libvirt USB passthrough support and pushed a fix: * Wed Sep 30 2009 Mark McLoughlin <markmc> - 0.7.1-7 - Fix USB device passthrough (#522683)
Okay, here's some more info: - libvirt in F-12 now supports re-labelling the sysfs files for USB passthrough, but only for devices specified by bus/device, not by product/vendor id - so, if you do: <source> <address bus='0XX' device='0XX'/> </source> instead of: <source> <vendor id='0x1d6b'/> <product id='0x0002'/> </source> then it *should* just work fine - if you stick with vendor/product, you need to do: $> setsebool virt_use_usb on - Now, it looks like we're broken in both of these scenarios currently because of this selinux AVC: type=SYSCALL msg=audit(1254334042.982:608): arch=c000003e syscall=2 success=no exit=-13 a0=5acdf2 a1=90800 a2=5 a3=7fffd314be50 items=0 ppid=1 pid=1823 auid=0 uid=107 gid=107 euid=107 suid=107 fsuid=107 egid=107 sgid=107 fsgid=107 tty=(none) ses=23 comm="qemu-kvm" exe="/usr/bin/qemu-kvm" subj=system_u:system_r:svirt_t:s0:c428,c710 key=(null) type=AVC msg=audit(1254334042.982:608): avc: denied { read } for pid=1823 comm="qemu-kvm" name="devices" dev=sysfs ino=1764 scontext=system_u:system_r:svirt_t:s0:c428,c710 tcontext=system_u:object_r:sysfs_t:s0 tclass=dir - It works fine in permissive mode, so this isn't a qemu issue
Weird, I was sure I added dwalsh already
Fixed in selinux-policy-3.6.32-17.fc12.noarch
