Hello! I''m investigate strange behaviour of vfb in paravirt domU (centos 5) VNC servers started after creating domain, but information in xenstore appears sometimes after 1-2 minutes after start. Why this happening? And how can i get VNC port immediate after creating of domU? Thank''s. -- Vasiliy G Tolstov <v.tolstov@selfip.ru> Selfip.Ru

Hi folks I tried to find a solution for the update problem. Currently I have 3 kernels, 2.6.16-16, 2.6.16-17 and 2.6.17-6 and each of them needs another hypervisor.
