[Pkg-xen-devel] Bug#441249: xen-hypervisor-3.0.3-1-i386-pae: "Problems using XEN when Quagga is running"
Package: xen-hypervisor-3.0.3-1-i386-pae
Version: 3.0.3-0-2
Severity: normal
If quagga is running, and I start & stop a domain, the VIF interface
doesn't go
down properly (in addition to other problems).
Here's what I do:
1. Boot the computer. By default, quagga is running (zebra + ospfd).
2. xm create test7.cfg, wait until the domU starts.
3. xm shutdown test7, wait until the domU stops. (I also tried halt from
within
domU)
4. xm list - gives me "Device 0 not connected" error after shutdown is
finished
5. "ifconfig vifX.0" still shows the interface.
6. xm create test7.cfg --> I get the "Hotplug scripts not working"
error
message
7. /etc/init.d/quagga restart
8. "ifconfig vifX.0" doesn't show the interface anymore
9. xm create test7.cfg now works as expected.
This might also be a bug of the quagga package.
See below to see the full attempt log:

It might be some interaction between the xen networking hotplug scripts and quagga... Are you using the standard vif-route scripts or have you customized them? Can you show us your quagga configuration too? Can you manually do on the xen interfaces what the scripts would? How about doing it on some other interface configured in a similar way? Can you try to insulate it within quagga? Does this happen if you just run zebra but not ospfd? Thanks! Guido
