It does take a little time to start, so it seems there should be a longer or configurable timeout.

Comment 1 Peter Krempa 2016-06-06 11:01:30 UTC

You need to install the 'xhtml1-dtds' package to be able to build libvirt from the git tree. This is not required when building the released .tar.gz packages.

Comment 2 jean-christophe manciot 2016-06-06 11:22:24 UTC

There is no such existing Ubuntu package.
The sources are located here: git://pkgs.fedoraproject.org/xhtml1-dtds
Do you know how to build it from those sources?

Comment 3 Cole Robinson 2016-06-06 12:49:06 UTC

pkgs.fedoraproject.org is not upstream sources, it's what contains the packaging definition and patches for fedora packages.

I googled 'libvirt ubuntu dtds' and found https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1469827 which sounds like the package is called w3c-dtd-xhtml

Comment 4 jean-christophe manciot 2016-06-06 14:26:48 UTC

Yes, building w3c-dtd-xhtml for Xenial from sources https://launchpad.net/ubuntu/+source/w3c-dtd-xhtml/1.2-4 and rebuilding libvirt 1.3.5 solves all related errors.
I have made it available alongside libvirt in my PPA for those who are interested in the latest Ubuntu packages: https://gitlab.com/jean-christophe-manciot/ppa
