I've managed to reproduce this with nightly RHEL7 host and a RHEL7 guest (f22 client). A f22 livecd guest (same host/same client) worked fine though. Actually, this was a configuration problem on my side, my VM only had a USB1 controller, not USB2. After making sure it's using a USB2 controller (uhci/ehci devices showing up in libvirt xml/qemu command line), the webcam is working fine on my 7.1 VM on a 7.2 host with f22 client. David, can you double check your VM configuration? (or even share it as I can no longer reproduce on my side). Hm, it's partly caused by qemu USB controllers and partly by guest OS:
* "Hypervisor Default" and "USB3" don't work in any guest tested
* USB2 works in Windows 7 and 8 (not exhaustive) and don't work in RHEL 7.2
"USB2" is the default multifunction device described by Hans in his initial blog posts:
<controller type='usb' index='0' model='ich9-ehci1'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x7'/>
</controller>
<controller type='usb' index='0' model='ich9-uhci1'>
<master startport='0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0' multifunction='on'/>
</controller>
<controller type='usb' index='0' model='ich9-uhci2'>
<master startport='2'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x1'/>
</controller>
<controller type='usb' index='0' model='ich9-uhci3'>
<master startport='4'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x2'/>
</controller>
"Hypervisor default" is:
<controller type='usb' index='0'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/>
</controller>
which in guest translates to:
$ lspci -s 00:01.2 -nn
00:01.2 USB controller [0c03]: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] [8086:7020] (rev 01)
"USB3 is":
<controller type='usb' index='0' model='nec-xhci'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</controller>

No, they're different: Controller \ Guest Fedora 22 RHEL 7.2 Windows 7 Windows 8 ================================================================= Hypervisor default -------------- Error ------------- USB2 - ich*hci* OK Error OK OK USB3 - nec-xhci -------------- Error ------------- (In reply to Christophe Fergeau from comment #4) ... > Can you do > echo 0xffff > /sys/module/uvcvideo/parameters/trace, redirect the webcam, > start cheese, and attach dmesg output?

That you get the same issue as in comment #0? (I assume this is what you implied, just making 100% sure) under investigation, not a blocker for rhel 7.2. moving to 7.3 Hi David, Could you try again with qemu-kvm-1.5.3-106.el7 as it address the problem from Bug #1268879 and I would like to be sure that the problems are unrelated? Thanks (In reply to Victor Toso from comment #10) > Hi David, > > Could you try again with qemu-kvm-1.5.3-106.el7 as it address the problem > from Bug #1268879 and I would like to be sure that the problems are > unrelated? Thanks I tried with -108 and I didn't get any error. The VM was different though (also 7.2 but fresh install of GA) as I already didn't have the old one. USB3 controller still doesn't work. *** This bug has been marked as a duplicate of bug 1268879 *** |
Created attachment 1066915 [details] spice-gtk log with 2 redirections of the webcam Description of problem: webcams not working over spice/usbredir in 7.2 hosts Version-Release number of selected component (if applicable): spice-server-0.12.4-13.el7.x86_64 qemu-kvm-1.5.3-101.el7.x86_64 / qemu-kvm-rhev-2.3.0-18.el7.x86_64 usbredir-0.6-7.el7.x86_64 libusbx-1.0.15-4.el7.x86_64 How reproducible: always Steps to Reproduce: 1. install a RHEL 7 nightly host, run a VM on it with usbredir enabled 2. connect to the guest, redirect a webcam to it 3. launch a webcam using app Actual results: * apps display black screen in place of video instead of some error * in spice-gtk debug output, libusb/usbredir messages cease after some time Expected results: video displays Additional info: * using the same clients, connection works fine for VMs on 7.1/6.6/6.7 hosts while failing on 7.2 hosts * downgrading spice-server and qemu* packages to 7.1 versions doesn't help * usbredir and libusbx are unchanged * boot to 7.1 kernel doesn't make any change either * tested guests: * several freshly-installed RHEL 7.1 * Windows 7
