Add redirdevs to ABI stability check
Check the bus, type of the source device (tcp vs. spicevmc)
and the device address visible in the guest.
https://bugzilla.redhat.com/show_bug.cgi?id=1035128
git describe: v1.2.3-38-gc9123fb
Verify the bug as follows. The result is expected.
Version:
libvirt-1.2.8-9.el7.x86_64
qemu-kvm-rhev-2.1.2-13.el7.x86_64
qemu-kvm-1.5.3-82.el7.x86_64
Preparation:
1. Plug in a usb device on host.
# lsusb
Bus 001 Device 007: ID 8644:8303
# usbredirserver -p 4000 8644:8303
2. Configure the guest with Redirected USB Device in virt-manager,
Add Hardware-> USB Redirection-> type: tcp, Address: 10.66.5.123, port: 4000.
3. Boot the guest.
4. Get the xml of the guest.
# virsh dumpxml r7 > mig.xml
...
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
...
Steps:
Scenario 1: change type
1.1 Change the type in mig.xml from 'tcp' to 'spicevmc'.
change xml from:
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
to:
<redirdev bus='usb' type='spicevmc'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
1.2 Do migrate.
# virsh migrate --live r7 qemu+ssh://10.66.106.26/system --xml mig.xml
root.106.26's password:
error: unsupported configuration: Target redirected device source type spicevmc does not match source device source type tcp
Scenario 2: change bus
2.1 Change the bus in mig.xml from 'usb' to 'pci'.
change xml from:
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
to:
<redirdev bus='pci' type='spicevmc'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
2.2 Do migrate.
# virsh migrate --live r7 qemu+ssh://10.66.106.26/system --xml mig.xml
root.106.26's password:
error: unsupported configuration: unknown redirdev bus 'pci'
Scenario 3: change devices count
3.1 Change the mig.xml as following.
change xml from:
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
to:
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
3.2 Do migrate.
# virsh migrate --live r7 qemu+ssh://10.66.106.26/system --xml mig.xml
root.106.26's password:
error: unsupported configuration: Target domain redirected devices count 2 does not match source 1
Scenario 4: no change
4.1 Don't modify mig.xml
<redirdev bus='usb' type='tcp'>
<source mode='connect' host='10.66.5.123' service='4000'/>
<protocol type='raw'/>
<alias name='redir4'/>
</redirdev>
4.2 Do migrate, no error shows.
# virsh migrate --live r7 qemu+ssh://10.66.106.26/system --xml mig.xml

Description Stable guest ABI doesn't check redirected usb device Version: libvirt-1.1.1-13.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Prepare a guest. 2.Plug in a usb device on host with usbredir packages installed. # lsusb Bus 006 Device 003: ID 15e1:2007 RSA RSA SecurID (R) Authenticator # usbredirserver -p 4000 15e1:2007 3. Configure the guest with Redirected USB Device in virt-manager, Add Hardware-> USB Redirection-> type: tcp, Address:&hostip,port as 4000. 4. Boot the guest. 5.Use virsh dumpxml to get the xml of the guest. # virsh dumpxml mig > mig.xml …… <redirdev bus='usb' type='tcp'> <source mode='connect' host='$ip' service='4000'/> <protocol type='raw'/> </redirdev> …… 6.Change the type in xml from 'tcp' to 'spicevmc'. change xml from: <redirdev bus='usb' type='tcp'> <source mode='connect' host='$ip' service='4000'/> <protocol type='raw'/> </redirdev> to: <redirdev bus='usb' type='spicevmc'> <source mode='connect' host='$ip' service='4000'/> <protocol type='raw'/> </redirdev> 5.Do migrate,no error shows. # virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml Actual results： As step 5 describes. Expected results: Error shows when type of redirected usb device in xml is different with guest. eg:error: unsupported configuration: Target redirected usb device type 'spicevmc' does not match source 'tcp'
