Please file a bug against libvirt, and include:
1) sudo virsh dumpxml $vmname
2) /var/log/libvirt/qemu/$vmname.log

Cannot start 2 VMs on F21
by Jerry James
Greetings,
I recently upgraded my work machine from F20 to F21, via fedup. Now I
cannot run two VMs at the same time, as I used to be able to do, at
least with virt-manager. If I try to start a second VM via
virt-manager, I get an error message:
------------------------------------------------------------------------------
Error starting domain: Unable to read from monitor: Connection reset by peer
Details:
Error starting domain: Unable to read from monitor: Connection reset by peer
Traceback (most recent call last):

Close
------------------------------------------------------------------------------
I can start any of my VMs, if there is no other VM running. After
starting any VM, attempting to start any other VM as a second instance
triggers this failure.
I will paste the contents of /var/log/messages from the latest
attempt. In this case, qemu-Rawhide32 is the VM that was already
running, and had been running for some time, so I don't understand the
"New machine" message. I'm trying to start the qemu-CentOS7 machine.

It looks like there is some kind of trouble setting up the network for
the second VM. Does anybody have any suggestions for things I could
try to resolve this? Are there known issues with upgrading from F20
to F21? Thank you,

Hmm, too bad. :(
Any chance you can try with 1.7 and 2.0 releases? Cole, perhaps you
help building some RPMS for Gerhard?

Hans, thank you very much. Removing the filter un-greyed the USB
devices. Obviously, I don't understand the filtering element - yet :).
I was hoping I'd be able to report that Rocksmith 2014 works great.
Unfortunately, although it installed without a problem, I am now
tracking down why it is generating a "Unable to initialize graphics
system" dialog <sigh>. So much for being an uber-geek. BTW, have any
of you played with the nwfilter feature of KVM? I ran into an odd bug
<https://bugzilla.redhat.com/show_bug.cgi?id=1114720> a while back and
there hasn't been any movement on it. I came up with a rubber band and
bubblegum solution which I mention in the bug report, so it's not an
emergency, just annoying. Spice is way cool as is this USB redirection
feature. Thank you both for writing it and help me.

Some USB devices are blocked by host policy
by Fred Brier
I'm using Spice and want to share a USB device on workstation with a VM
running on another physical host. The filters are all set up for the VM
in its domain XML. The Spice "Select USB devices for redirection"
dialog shows the device I want to redirect. However, all the USB
devices are greyed out and Alert text says, "Some USB devices are
blocked by host policy". My understanding, from the doc
<https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/...>,
is that the following XML needs to be configured on the "host physical
machine's domain XML" which I am interpreting as the workstation,
although it could be the hypervisor host, to unblock the USB device:
<redirfilter>
<usbdev class='0x08' vendor='0x0951' product='0x1625' version='2.0' allow='yes'/>
<usbdev allow='no'/>
</redirfilter>
Either way, I cannot figure out what the name or location of the file
where this XML would go, let alone find a complete schema or example of
what the file would look like. Has anyone else done this? Please...
<gasp> Help!
