OracleVM is there for free... ;-) And I never got, what was so attractive
about Xen in Solaris... ;-) FOR ME (and I put it in capital letters, as I
know, there will be many flaming me hereafter) a hypervisor is the new
"BIOS". And shouldn't be seen as more. It's a tool, some "small" software to
help you run an OS on a virtualized infrastructure. If it works, it works.
OK, now for the part, that will get me flamed...
The arguments, that dtrace et.al. might be used in Xen, are not enough for me
to support the further "apoption" of Xen to Solaris: Dtrace NEVER was a
synchronous part and NEVER had guaranteed access to the Xen-internals
(technically not feasable). Crossbox might be seen as an advantage in the
Dom0, yes, but that part could be added to OracleVM, I guess. ZFS in the dom0,
why? In architectures of a bigger size, the storage for the DomU will NOT be
hosted on the same physical box, so some kind of network access is there, be
it iSCSI, NFS or FC (SAN). That leaves the classical "I don't want to learn a
new OS" question. If you hide the config and management of the OracleVM with a
good GUI (just like VMware does with the "Linux" inside), why worry?
OK, these are all my thinking.
So, we need Solaris to be a GOOD domU, and that will be the case!
So, Stefan, where do you see the superiority of Solaris as a dom0?

Ever heard of Oracle suing a single person? So, yes, there might be the 90-day
thing, et.al., still, all my new Oracle colleagues re-affirm myself, that they
don't believe, that the single individual might get into trouble. Yes, I see,
that for S(mall)M(edium)B(usiness)es there might be a new risk, but whoever
wanted Solaris wanted to PROFIT from its quality. And quality might always
have a price, right? There MUST be a reason, why Sun is no more... ;-) And I
would not blame it one the quality aspect of Solaris... ;-)

Right, but in all cases, Oracle never really announced stuff so much in
advance as Sun did... So, that's a change in external behaviour, but not
necessarily an indication of a different underlying attitude towards the
product Solaris itself...
