Summary: Cannot create bridged network for paravirtualized guest. Product: Fedora Version: 8 Platform: ia64 OS/Version: Linux Status: NEW Severity: high Priority: low Component: xen AssignedTo: xen-maint@redhat.com ReportedBy: sella@digital-genesis.com QAContact: extras-qa@fedoraproject.org CC: berrange@redhat.com,fedora-triage- list@redhat.com,sella@digital-genesis.com
+++ This bug was initially created as a clone of Bug #386151 +++
Description of problem: I cannot create a bridged network connection using either virt-manager or virt-install. Virt-manager does not allow me to specify a shared interface (paravirtualized guest) - the space contains no choices. When I try to create the guest using virt-install, I specify --network briege:eth0 and get hotplug errors of this type: can't add vif1.0 to bridge eth0: Operation not supported
Version-Release number of selected component (if applicable): xen-3.1.0-8.fc7.i386 libvirt-0.3.3-1.fc7.i386
How reproducible: Always happens.
Steps to Reproduce:
1. virt-install -p -n fed8p -r 1000 -f /var/lib/xen/images/fed8p -s 8 -l http://download.fedora.redhat.com/pub/fedora/linux/releases/8/Fedora/i386/os... --os-type=linux --os-variant=generic26 --network bridge:eth0 2. Follow the installation sequence until the network setting step. Specify dhcp and the boot will hang (and then return to the network set up question) 3.
Actual results: Guest installation cannot get past the network set up question.
Expected results: Normal installation

-- Additional comment from moose@quadruped.com on 2007-11-16 07:52 EST -- I should note that this is the i386 version of Fedora 7 running on x86_64 hardware (a Dell Precision 690). I see this problem regardless of SELinux setting (I' ve tried enforcing, permissive, and disabled - albeit without any reboots between attempts).

I rebooted my machine and examined the xend log. Please note the errors indicating failures to create network bridges. What do I have to do to avoid these? Is this a known problem with Fedora 7, a problem with my platform, or some obscure configuration error?
-- Additional comment from sella@digital-genesis.com on 2008-03-23 18:18 EST -- I've run into this issue on both Fedora 7 and Fedora 8. In both cases, it only happens after I update the system with yum. It appears to be an issue with dbus or how virt-manager works with it.
Using virt-manager to create new bridged Xen virtual machines works fine after a fresh install. After I use yum to update the system I'm no longer able to create virtual machines with bridged interfaces. Specifically, in virt-manager on the "Connect to a Host" screen, the "Shared physical device" option has an empty drop down for "device".
Below is a fix that worked for me with Fedora 8 (didn't try Fedora 7):
On the updated system, as root, mount the install DVD and change to the directory containing your original set of RPMs ("Packages" with Fedora 8, "Fedora" with Fedora 7), then reinstall the old RPMs for dbus, dbus-libs and dbus-x11.
Example:
# cd /media/disk/Packages # rpm -Uvh --oldpackage dbus-1.1.2-7.fc8.x86_64.rpm dbus-libs-1.1.2-7.fc8.x86_64.rpm dbus-libs-1.1.2-7.fc8.i386.rpm dbus-x11-1.1.2-7.fc8.x86_64.rpm
*NOTE: You may need to specify other packages if RPM complains about dependencies.
This fix is very similar to one mentioned for RHES5.1 here:
http://www.linuxquestions.org/questions/linux-enterprise-47/virt-manager-in-...
There is also mention of the same issue in CentOS-5, which they resolve by patching /usr/share/virt-manager/virtManager/connection.py. Description and patch is here:

------- Additional Comments From dchapman@redhat.com 2008-06-24 12:17 EST ------- This is not ia64, that is likely why it was never addressed. Moving to i386 since it appears that is what the user was using.
