This is also a problem with virt-install:

Thanks for the report, please provide virt-install --debug when reproducing

That error comes from src/libxl/libxl_conf.c:libxlMakeVideo . virt-install isn't adding an explicit video ddevice, so the default video dev is being added, and I suspect some part of the code isn't setting video ram correctly, or libxl should be updated to expect ram=0 or whatever the value is by default.

Unfortunately the libvirt unit test suite doesn't seem to touch this code, I tried editing one of the tests in xlconfigdata/ but it didn't trigger

This bug was introduced by libvirt commit 6879be48. I've sent a patch upstream that fixes the issue in my testing

https://www.redhat.com/archives/libvir-list/2016-May/msg00700.html

In libvirt 1.3.3-maint now

Do you have a test-build I could try out?

Thanks!

I kicked off a scratch build here;

http://koji.fedoraproject.org/koji/taskinfo?taskID=14108914

OK, I downloaded it and installed it.

Now I get:

nable to complete install: 'unsupported configuration: videoram must be at least 8MB for CIRRUS'

Umm?

which is the libvirt RPMs built from http://koji.fedoraproject.org/koji/taskinfo?taskID=14108918 scratch build.

I suppose some patches are missing. On top of 1.3.4 I have e4d131b8, 3e428670, 538012c8, 96b21fb0, and b90c4b5f to fix this bug. Note that 96b21fb0 and b90c4b5f are only adjusting tests to allow 'make check' to pass.

I pulled in all of those. Konrad can you double check that libvirtd was restarted? I could have botched the build though

I rebooted the box after I did the install. And just to make sure there were no odd things around I first did 'dnf remove libvirt' and then did 'dnf install libvirt' (with adjusting my local repo to be picked over the updates which had the same version).

Pls keep in mind that the error is different - initially it was 4MB, now it is 8MB so there is a fix in there.

Just rebooted the box once more just in case. Same error.

I just confirmed that the test build fixes the issues for me. What RPMs did you update? Make sure libvirt-daemon and libvirt-daemon-driver-libxl were included. You can use 'koji download-task 14108918' to download all the RPMs

I am not sure why it did not work for me before.

But I ended up removing all libvirt and then re-intalling (this this using the new repo). And it all worked!

Thank you!
