Hi all,
Looks like that it is possible to use vnic interfaces in current release
of OpenSolaris. (for example, this ability is described in the article
http://unixsysadmin.net/2008/07/17/create-a-vnic-on-solaris-nevada-solaris-express-builds-and-use-it-for-an-exclusive-ip-stack-in-zones/)
I have tried to use this feature, as a result I got 'virtual' network on
my laptop for developing purposes. I even can user snoop for debugging
my distributed web application. Very helpful!
But there is an issue: the system is crashed when the command 'pfexec
zoneadm -z web halt ' is executed. A workaround is the command
'#ifconfig vnic1 unplumb' in the zone before halting (I'm not certain
that the workaround works always).
May be I do something wrong, may be vnicN interfaces should not be used
yet because Crossbow is not included into release 200811. May be I
should fill a bug. Commands and piece of system dump are below. Could
you help me to resolve the issue?
Thanks,
Vitaly
