Hi, Is it possible to update kernel and hypervisor on opensolaris dom0 to xen 3.2.1? I tried replacing just the hypervisor on an up-to-date opensolaris 2008.05 (snv_91), it failed. Does it require the same workaround as when using opensolaris as domU on a xen-3.2 dom0? Regards Fajar

Should panic during boot, because a dom0 / 3.1.x hypervisor interface is needed, and the 3.2.x hypervisor interface is slightly incompatible.> Does it require the same workaround as when using > opensolaris as domU on a xen-3.2 dom0?No, the dom0 / hypervisor interface has changed in incompatible ways. domU / hypervisor interface is less critical, and it should be possible to run domUs on xen 3.0, 3.1, 3.2 or xen unstable(3.3) hypervisors. But even that breaks from time to time, e.g. see bug 6650717 (snv_86 or older domU doesn''t work on a 3.2 hypervisor). This message posted from opensolaris.org

Builds have already Xen 3.1.2 , but not patched. This message posted from opensolaris.org
