in part,

"I believe OS 2009.06 DomU by default does DHCP request at startup. If
it fails you get a problem."

as detailed in my prior posts, it's not (yet) working here ...

admitting i'm 'new' to this, this install is cumbersome, at best.
tbh, a far cry from the "it works" messages from speakers &
product_mgmt received at JavaOne "-/

i suppose i'll have to do that, but frankly a bit surprised that that
would not have been considered already -- static-ip deployments, of
servers in particular, are not particularly uncommon ...

likely doable ... but, again, DHCP is not going to be an option here
at all (eventually) ...

iiuc, i believe that'd be,

pfexec svcadm disable network/physical:nwam && \
pfexec svcadm enable  network/physical:default
pfexec ifconfig xnf0 down
pfexec ifconfig xnf0 192.168.1.102 netmask 255.255.255.0 mtu 1492
pfexec ifconfig xnf0 up
pfexec route add default 192.168.1.102

which i can/do @ installer time to use static IP assignements.  i just
can't seem to get them to 'stick' or 'be happy' after reboot and xen,
run-time launch.

> It's not a problem for Solaris Nevada. Installer it self suggested static IP configuration. The last build i tried was 106.

@ JavaOne i was repeatedly told that SXCE (that's 'Nevada', yes?) is
"going away soon" and that I should be using opensolaris _now_.

given these experiences, i'm not sure that's the wisest choice,
particularly for a server deployment in a static-ip env.

given your coment, Boris, and reading,

  http://whacked.net/2005/06/21/confused-so-was-i/

is 'Nevada' likely a more-functional, or at least better-behaved,
option for me?
