Package: virt-manager
Version: 1:1.0.1-2.1
Severity: important
Hi.
Today I've stumbled over server issues when creatig
VNC/SPICE servers from within virt-manager.
1) It started with that I tried to change the type
of a Display Server hardware in a VM from VNC to
SPICE via the dropdown list.
Which makes a popup with the title:
Error changing VM configuration: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0da6d50>'
And message:
Error changing VM configuration: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0da6d50>'
Traceback (most recent call last):

if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self)
libvirtError: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0da6d50>'
Just deleting the "hardware" and readding it doesn't help either.
2) I assumed that maybe the format of the XMLs have changed
so I removed all VMs from /etc/libvirt/qemu and started from
scratch.
Now when I now create a VM, and select "configure before
installation".
And try to change (actually "set" it - since it's unset)
the Display Server type there, something even more creepy
happens, which you can see on the attached screenshot.
If I start completely over from scratch and do *not*
change the type of the Display Server during the "configure
before installation"... it actually creates the VM with a
SPICE server (the type is then set after installation o.O).
3) Now at that point when I try to configure the spice server
i.e. change Address from "Hypervisor default" to "Localhost
only" (which IMHO should be default for security reasons
aynway)
Something completely awkward happens:
The first time I try to set/apply it I get this error:
Error changing VM configuration: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0d6ac10>'
Error changing VM configuration: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0d6ac10>'

if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self)
libvirtError: unsupported configuration: unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7f16b0d6ac10>'
When I then click to another part of the VM (other hardware)
and afterwards try it again, localhost+apply.
It gives no error, but the dropdown shows "Hypervisor default"
again.
When repeating that once more (i.e. going to some other hardware,
then back, then localhost+apply) it gets a popup:
Error changing VM configuration: xmlParseDoc() failed

File "/usr/lib/python2.7/dist-packages/libxml2.py", line 1325, in parseDoc
if ret is None:raise parserError('xmlParseDoc() failed')
parserError: xmlParseDoc() failed
Apply doesn't work then, I can only click cancel.
When I then restart virt-manager.
The whole VM is no longer shown (even though the XML is still there,
though corrupted I guess).
All this seems to be 100% reproducible every time,
but if you still like me to do the debug logs
(--debug --no-fork), just tell me.
Thanks,
Chris.
