Re: [libvirt] [PATCH] Fix probing of legacy Xen driver to not leave URI set

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When the legacy Xen driver probes with a NULL URI, and finds itself running on Xen, it will set conn->uri. A little bit later though it checks to see if libxl support exists, and if so declines the driver. This leaves the conn->uri set to 'xen:///', so if libxl also declines it, it prevents probing of the QEMU driver. Once a driver has set the conn->uri, it must *never* decline an open request. So we must move the libxl check earlier Signed-off-by: Daniel P. Berrange <berrange(a)redhat.com&gt; --- src/xen/xen_driver.c | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-)
