Hi!
I ran into a problem using a USB device and was wondering if
you could help me.
I'm running a Win XP SP3 in a VM with libvirt on a Xubuntu 11.10.
I configured it to talk to several USB devices.
With one particular device (a Phonak Compilot[1], admittedly a probably
rather unusual device), the VM dies with the following error in the
libvirtd.log:
2012-07-20 21:04:19.591+0000: 1282: error :
virConnectNumOfInterfaces:9803 : this function is not supported by the
connection driver: virConnectNumOfInterfaces
2012-07-20 21:05:05.762+0000: 1276: error : qemuMonitorIO:603 : internal
error End of file from monitor
This happens no matter if is it the only configured USB device or if
there is another USB device present in the config or not.
I configured it doing the following steps:
- I looked up the vendor / product ID using lsub
Bus 001 Device 003: ID 180f:1002
(Interestingly, it does not show a name of the device here.)
- I added it to the VM's xml configuration using virsh / edit $vmname
<domain>
...
<devices>
...
<hostdev mode='subsystem' type='usb' managed='no'>
<source>
<vendor id='0x180f'/>
<product id='0x1002'/>
</source>
</hostdev>
...
</devices>
</domain>
- I run the VM using the virt-manager UI.
Any ideas what the problem could be? Do I need to run/configure
differently than how I did it? To me it sounds as if there is some
implementation missing? Is there a workaround for it?
I hope you can give me some clues.
Thank you!
Helga

This message is guaranteed unrelated to your guest dying. It means that
some management program (for example virt-manager) is trying out the
"virInterface" part of libvirt's API, and discovering that your platform
does not support that part of the API. the virInterface functions deal
with configuring and reporting the status of the host's network devices
(physical ethernets, bridges, bonds), are only supported on platforms
that have the "netcf" library, and are optional. Ubuntu is only just now
getting netcf support into their distro, do Xubuntu 11.10 will certainly
not have it.
TL;DR ignore the error about virConnectNumOfInterfaces.
2012-07-20 21:05:05.762+0000: 1276: error : qemuMonitorIO:603 :

error End of file from monitor
This just means that the qemu process terminated abruptly. If you look
in /var/log/libvirt/qemu/${guestname}.log, you may find a more specific
error message issued by qemu itself.
In the meantime, it would be helpful when reporting problems to tell us
the version of libvirt and qemu that are installed.
This happens no matter if is it the only configured USB device or if
there is another USB device present in the config or not.

The XML looks fine to me (the "managed='no'" part would only be
relevant
for PCI devices, not USB, but it would be ignored in this case, so
that's not a problem).
To help figure out what may be the problem, do this:
1) try starting the guest from the shell with "virsh start
${guestname}", and send any error message that produces. Also let us
know the versions of libvirt ("virsh -v" will give you that) and qemu
(or kvm - different platforms have different names for the packages) -
various older versions of libvirt have various bugs, and knowing the
version helps us to narrow down possibilities.
2) After virsh start fails, look at the end of
/var/log/libvirt/qemu/${guestname}.log - send everything starting from
the last qemu (or maybe it's kvm in your distro) commandline to the end
of the file.
3) Just to verify that the problem really is in the USB device
definition, use virsh edit to remove it, then retry the start.

Okay, thanks for the explanation! I appreciate it.

This just means that the qemu process terminated abruptly. If you look
in /var/log/libvirt/qemu/${guestname}.log, you may find a more specific
error message issued by qemu itself.
Okay, I did that and here is the full log of my try to start it up:

Any idea what this assertion means? Googling did not really help me here.
In the meantime, it would be helpful when reporting problems to tell us
the version of libvirt and qemu that are installed.
virsh -v gives me version 0.9.8, version of my qemu-kvm package is
"1.0+noroms-0ubuntu13"
I installed those simply by using aptitude, I did not do anything special
here.

The XML looks fine to me (the "managed='no'" part would only be

that's not a problem).
To help figure out what may be the problem, do this:
1) try starting the guest from the shell with "virsh start
${guestname}", and send any error message that produces. Also let us
know the versions of libvirt ("virsh -v" will give you that) and qemu
(or kvm - different platforms have different names for the packages) -
various older versions of libvirt have various bugs, and knowing the
version helps us to narrow down possibilities.
Versions as mentioned above: libvirt 0.9.8 and kvm-qemu 1.0+noroms-0ubuntu13
I tried to run the guest from the shell, but it does not show much:
virsh start $guestname
WARNING: gnome-keyring:: couldn't
connect to: /tmp/keyring-hiKzI0/pkcs11:
No such file or directory
Domain $guestname started
(I guess the keyring warning does not matter since it also appears when I
run the vm without the troublesome USB device and then the guest does not
die.)
Other than that, nothing happens here. At the same time I observed the log
of the guest. The result is the same as mentioned in this email further up.
2) After virsh start fails, look at the end of
/var/log/libvirt/qemu/${guestname}.log - send everything starting from
the last qemu (or maybe it's kvm in your distro) commandline to the end
of the file.
See above. Same as before.
3) Just to verify that the problem really is in the USB device
definition, use virsh edit to remove it, then retry the start.
Did so, the guest starts without any problems. I checked the log which
looks the same with the exception that the line with the failed assertion
is not there.
Thanks for your help so far, I hope you can give me a hint what the problem
is!
Cheers,
Helga

This is some internal problem in qemu-1.0. You'll need to ask about it
on a qemu mailing list or irc channel - the commandline and error above,
along with telling them your exact version of qemu should be enough to
get them going. (I looked it up in the source and one thing I can tell
you is that the *entire file* containing this assertion ("assert
edp->type == INVALID_EP_TYPE") was removed between qemu-1.0 and
qemu-1.1. It may be that the simplest way to eliminate the problem is to
get a build of qemu-1.1)

project.
