[Xen-users] [Q] VmError: Disk isn''t accessible with tap2:tapdisk:vhd
I''m newbie Xen-4.1.1
I''m trying to boot DomU with the following configuration.
Sometime DomU boot, but sometime boot failed
I''m not sure what is the problem.
I can attach that image with tap-ctl on Dom0.
Does anybody advice me about this problem??
Sincerely
