[Xen-users] SETVCPUCONTEXT failed

[chrisbenninger <chrisbenninger@xxxxxxxxx>]

Hi guys,

I cannot get my domU's to boot. My current setup is as follows:

Xen: 4.0.1

Dom0: Debian with custom linux 2.6.32.27 Xen kernel

DomU: Same kernel as Dom0

When I try to start the VM, I just get:

> Error: (1, 'Internal error', 'launch_vm: SETVCPUCONTEXT failed (rc=-1)\n')

And /var/log/xend.log says:

I have tried tweaking the initramfs images because I thought I was missing a module of some kind, but I can't seem to isolate it if that is in fact the cause.
