[Pkg-xen-devel] Bug#441249: Bug#441249: xen-hypervisor-3.0.3-1-i386-pae: "Problems using XEN when Quagga is running"

[Mikko Korkalo]

Hi,

Toying with the vif-route script, I might have found a workaround for this
issue.
If I disable the ifconfig and ip route commands from vif-route script, and bring
up vif interface by hand later on, everything seems to work.

In other works, bringing up the interface in vif-route script causes it to stay
up when I shutdown the domain.

I'm not sure though if the workaround is stable, as I again experienced a crash
like before ("kernel BUG at drivers/xen/core/evtchn.c:481!") when doing a lot
of create/shutdown commands, manually bringing up interfaces, etc. I haven't
found a reliable way to reproduce the crash yet.

I need to do more testing before I can say for sure.

What do you think of this?

If only zebra is running - still a jammed VIF interface.
If only ospfd is running, it actually fixes the problem. (too bad ospfd is
useless without the zebra daemon)

By the way, if you want I could arrange you an SSH access to the xen1 host.
