RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Milan Barta 2012-07-23 14:46:28 UTC 
Description of problem:
When a USB flash drive is connected to a Fedora/RHEL7 (x86_64) guest (using remote-viewer on RHEL 6.3 client and host) after a while the drive gets disconnected.
With Windows 7 guest the usb redirection works as expected.

remote-viewer error message:

Version-Release number of selected component (if applicable):
RHEL 6.3 (both client and host)


How reproducible:
Running a Fedora/RHEL guest.

Steps to Reproduce:

Since virt-manager in RHEL 6.3 doesn't support the usb redirection setup, the domain XML config file needs to be edited:

    sudo virsh edit  $GUEST_NAME" on host machine.
    enter above the "</devices>" line following:

  <controller type='usb' index='0' model='ich9-ehci1'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x7'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci1'>
      <master startport='0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0' multifunction='on'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci2'>
      <master startport='2'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x1'/>
    </controller>
    <controller type='usb' index='0' model='ich9-uhci3'>
      <master startport='4'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x2'/>
    </controller>
    <redirdev bus='usb' type='spicevmc'>  
      <address type='usb' bus='0' port='3'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <address type='usb' bus='0' port='4'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <address type='usb' bus='0' port='5'/>
    </redirdev>
    <redirdev bus='usb' type='spicevmc'>
      <address type='usb' bus='0' port='6'/>
    </redirdev>

The guest system is run using the virt-manager:

1. run remote-viewer spice://$HOST?port=$PORT
2. connect a flash drive
3. mount the flash drive in guest system
4. wait ...
  
Actual results:
The flash drive gets mounted. After a while it disconnects.

Expected results:
The flash drive stays mounted until unmounted.

Comment 1 Hans de Goede 2012-07-23 14:56:31 UTC 
2 questions:
1) Are you perhaps using the device in a USB-3 port of the client ?  If so can you try using it in a USB-2 port
2) Can you reproduce the problem and attach dmesg from the client machine please?
Comment 3 Milan Barta 2012-07-23 17:26:17 UTC 
1) my workstation only has USB2 ports, no USB3.
2) client dmesg:

Comment 4 Paul Vine 2012-07-25 18:55:44 UTC 
Moving to 7.0 as 6.3 combinations are fine so it is likely the bug is with 7.0.
Comment 5 Hans de Goede 2012-07-28 15:30:24 UTC 
So looking at the dmesg inside both the client and the guest what is happening is:
1) device gets redirected
2) the guest issues a ton of device resets due to some errors while talking to the device
3) after devie reset 1001 and the device goes into some error state and no longer wants to talk to the problem

There is little we can do to fix 3, if you keep hitting the device with resets eventually you may do so at a bad time and the firmware may lockup. So the problem to fix here is 2. To fix 2) I will need some more information, can you please try running the RHEL-7 guest with usbredir debugging enabled?

To do this you (unfortunately) will need to start qemu manually, since libvirt does not support the debug parameter of the usb-redir device (I'll file a bug for this).

Here is an example commandline for running RHEL under qemu-kvm directly from the cmdline:

/usr/bin/qemu-kvm -enable-kvm \
 -m 1024 -name RHEL-7 \
 -drive file=/home/images/rhel7.img,media=disk,index=0 \
 -net nic,macaddr=52:54:00:7a:b4:7e,vlan=0,model=virtio,name=virtio.0 -net user,vlan0 \
 -vga qxl -spice port=5955,disable-ticketing \
 -device virtio-serial -chardev spicevmc,id=vdagent,debug=1,name=vdagent -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
 -readconfig /home/hans/projects/qemu/docs/ich9-ehci-uhci.cfg \
 -chardev spicevmc,name=usbredir,id=usbredirchardev1 \
 -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=4 \
 -chardev spicevmc,name=usbredir,id=usbredirchardev2 \
 -device usb-redir,chardev=usbredirchardev2,id=usbredirdev2,debug=4 \
 -chardev spicevmc,name=usbredir,id=usbredirchardev3 \
 -device usb-redir,chardev=usbredirchardev3,id=usbredirdev3,debug=4 \
 -monitor stdio -device intel-hda -device hda-duplex 2> qemu.log

Notice you will need to drop ich9-ehci-uhi.cfg somewhere and adjust the -readconfig to point there. You can find the .cfg file here: http://cgit.freedesktop.org/spice/qemu/plain/docs/ich9-ehci-uhci.cfg

Then connect to lthe vm with remote-viewer, redirect the troublesome USB-stick, let it run for a while and attach qemu.log here.

Comment 8 Hans de Goede 2012-07-30 10:20:52 UTC 
Thanks for generating the log, this looks like it may be an issue fixed by a  recent  upstream fix, can you try with a Fedora-17 client with this version of usbredir installed:   ?

Comment 9 Milan Barta 2012-07-30 14:00:35 UTC 
Tried running Fedora 17 client and the problem doesn't seem to occur anymore.

That is good news, thanks for the info.

Ok, that would make this a duplicate of bug 834560 .
