Moreover, I have tried to use the kernel from my host Ubuntu (vmlinuz-2.6.24-21-server) and error was the same. However, using vmlinuz-2.6.24-21-xen kernel still worked fine, but in paravirtualized mode I suppose. All the kernels and initrds I have tried to use were taken from /boot/ without any additional modifications. Is it correct usage for full virtualization or some tuning should be performed? Or maybe Ubuntu as a host doesn't support full virtualization for direct kernel boot at all? -- Max -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
