Description Cole Robinson 2014-12-17 18:34:41 UTC 
See fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=1135488

If we default to adding 4 usbredir devices, we fill up all the emulated USB2 slots, and directly assigned devices are forced to fall back to USB1

This upstream commit changes the default to 2 usbredir devices, we should pull it into RHEL:

    guest: Limit number of default usb redirdevs to 2 (bug 1135488)
Comment 6 CongDong 2015-01-12 09:45:53 UTC 
With virt-manager-1.1.0-10.el7.noarch

1. #virt-manager 
2. install a guest
3. double click the guest to open it, click "Details" button
4. check the hardware list

Result:
there are 4 usb redirector devices in the list
"USB Redirector 1"
"USB Redirector 2"
"USB Redirector 3"
"USB Redirector 4"

Verify with virt-manager-1.1.0-11.el7.noarch

Result:
Just two usb redirector devices in the list
"USB Redirector 1"
"USB Redirector 2"

Do you think the steps are enough to verify this bug?
Comment 7 Giuseppe Scrivano 2015-01-12 11:43:11 UTC 
yes, these steps show there are only two usb redirector devices added by default.
Comment 8 CongDong 2015-01-12 11:54:32 UTC 
As comment 6 and comment 7, move to VERIFIED
