Re: [Xen-devel] Freeze on boot pv domU 2.6.31 with Xen 4.1
I upgraded Xen to the last revision on the repository (21446) and
installed it. 2.6.31.13 kernel (branch xen/stable-2.6.31.x) do not hang at
boot time anymore (I have a 2.6.31.13 kernel on both Dom0 and pv DomU).
Netchannel2 is added (and appears in guest), nevertheless, I get a triple
fault from Xen's kernel when I try to start a dhcp client on the
netchannel2 interface. Here is the crash report on Xen's console :
