Hello folks,
I' trying to start with Xen with SuSE 10.0
The XEN microcernel is 3.0_7608, the xenified kernel is 2.6.13-15.7
The microkernel and domain0 starts well.
But when I try to start one more domain - either the ttylinux image or
an image prepared by suse, xm can't start xen with following error:
Error: Error creating domain: Device 2049 (vbd) could not be connected.
Hotplug scripts not working
Any ideas, what the reason can be?
Regards,
Eduard
