[Xen-users] Error: Device 2049 (vbd) could not be connected. Hotplug scripts not working

[Vinogratzky <vinogratzky@xxxxxx>]

Hi,

have a debian 5.0 with all patches and xen 4.3.1 (debian repo)
installed. If I use a VM with paravirtualizing it works fine.
But a full virtualized image doesn't boot.

Message:

# xm create deb50.cfg:
Error: Device 2049 (vbd) could not be connected. Hotplug scripts not working.

That is my deb50.cfg

After xm create:

# xm list

but the console doesn't work:
---8<---
# xm console deb50
xenconsole: Could not read tty from store: No such file or directory
---8<---

CPU: Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz
If I boot a non xen-kernel, I get the "vmx" cpu flag.


Google didn't help me either.
