Re: [Xen-users] some domUs work, some dont..??



I just figured also out that it might not be a problem depending on the
xen-tools because the same domU that failed to start 1 hour ago started
now. But when i try to start another one (that has already been started
or just created) it might not start again...So it might be a kernel or
xen problem (i guess...)
