Cannot read MAC in a Zone Container
Hi,
I have an app which reads MAC address. I read that Solaris 10 8/07 offers the solution to set MAC address for each container but I cannot find how to do that in any docs I found on Sun
do you know how ?
True that installed I only have Solaris 10 5/08. In a container zone it generates errors:
bash-3.00# ifconfig -a
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 172.16.151.101 netmask ffffff00 broadcast 172.16.151.255
bash-3.00# ./myapp
open device fail = /dev/e1000g
Error:[Error] Can't get any mac address infomation. check your network card.

crw-rw-rw- 1 root root 87, 1 Feb 24 18:21 /dev/e1000g0
bash-3.00#
The network card is e1000g0 not e1000g

When I created the zone:
zonecfg:xenon-zone> add net
zonecfg:xenon-zone:net> set address=172.16.151.101
zonecfg:xenon-zone:net> set physical=e1000g0

zonecfg:xenon-zone> add device
zonecfg:xenon-zone:device> set match=/dev/e1000g0
zonecfg:xenon-zone:device> end

On our Solaris 10 servers we have shared NIC interfaces. We have a program that is having issues talking to the all zones because they have the same MAC address.

Hi, hoping someone can help, its been a while since I used Solaris.
After creating a NGZ (non global zone), the NGZ can access the GZ (Global Zone) and the GZ can access the NGZ (using ssh, zlogin)
However, the NGZ cannot access any other netwqork devices, it can't even see the default router

xvif
XVIF(4) BSD/xen Kernel Interfaces Manual XVIF(4) NAME
xvif -- Xen backend paravirtualized network interface SYNOPSIS
pseudo-device xvif DESCRIPTION
The xvif interface forms the backend part of the paravirtualized drivers used by Xen domains to offer network connectivity. When the guest domain is NetBSD, the endpoint of the xvif interface is a xennet(4) interface. In the XenStore, xvif and xennet are identi- fied by ``vif'' (virtual interface) entries. All xvif interfaces follow the ``xvifXiY'' naming convention, where 'X' represents the guest domain identifier, and 'Y' an arbitrary identi- fier; most of the time, it is the frontend interface identifier, e.g. ``xennetY''. For convenience, the MAC address of an xvif interface is chosen by incrementing the third byte of the MAC address of the frontend device. Conceptually, frontends and backends drivers are similar to two Ethernet cards connected via a crossover cable. DIAGNOSTICS
xvif%di%d: can't read %s/mac: %d The MAC address for this interface could not be read from XenStore. xvif%di%d: %s is not a valid mac address The MAC address specified in the configuration file of the newly created guest domain is invalid. xvif%di%d: Ethernet address %s MAC address of the xvif interface. SEE ALSO
ifmedia(4), xennet(4), ifconfig(8) HISTORY
The xvif driver first appeared in NetBSD 4.0. AUTHORS
The xvif driver was written by Manuel Bouyer <bouyer@NetBSD.org>. BSD
