There is a bug in the version of libvirt (1.2.9.1) that ships with Fedora 21, where the vhostuser interface mode can only be set to server and not client. The option to set either is required when using vhost-user with OpenvSwitch. However a fix has been merged for this issue and is available on libvrt-1.2.10: commit 302720742f6e159af45631475d720cf807e905b9 Author: Maxime Leroy <maxime.leroy> Date: Fri Oct 17 18:45:18 2014 +0200 conf: tests: fix virDomainNetDefFormat for vhost-user in client mode The mode attribute is required for the source element of vhost-user. Thus virDomainNetDefFormat should always generate a xml with it and not only when the mode is server. The commit fixes the issue. And it adds a vhostuser interface in 'client' mode to qemuxml2argv-net-vhostuser.(args|xml) to test this usecase. Can libvirt-1.2.10 be made available for Fedora 21 via yum ?
Thanks for the report. We don't rebase new versions of libvirt into stable fedora (except libvirt maint releases), but I can backport the patch. If you need libvirt 1.2.10 on fedora 21 I suggest using fedora virt preview: http://fedoraproject.org/wiki/Virtualization_Preview_Repository
Hi Cole Ok, we can use the virt preview repo. Thanks
