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.

The xvif driver first appeared in NetBSD 4.0.

xennet -- Xen frontend paravirtualized network interface
SYNOPSIS
xennet* at xenbus?
DESCRIPTION
The xennet interface forms the frontend part of the paravirtualized drivers used by Xen guest domains to have network connectivity.
When the host domain is NetBSD, the endpoint of the xennet interface is a xvif(4) interface. In the XenStore, xvif and xennet are identified
by ``vif'' (virtual interface) entries.
Conceptually, frontends and backends drivers are similar to two Ethernet cards connected via a crossover cable.
DIAGNOSTICS
xennet%d: can't read mac address, err %d The MAC address for this interface could not be read from XenStore.
xennet%d: %s is not a valid mac address The MAC address specified in the configuration file of the newly created guest domain is invalid.
xennet%d: using event channel %d The Xen event channel (virtual interrupt) ID associated to this xennet.
xennet%d: using RX copy mode The xennet and its associated endpoint use copy mode for communication: packets are copied from one domain's
memory to another.
xennet%d: using RX flip mode The xennet and its associated endpoint use flip mode for communication: packets are passed by remapping memory
pages between domains.

hi,
I have written a script to search MAC address in a given directory.
MAC address would be in format XX.XX.XX.XX.
The digits contain hexadecimal numbers.
For this i have used grep as follows.
grep -rn '^\{1,2\}\.\{1,2\}\.\{1,2\}\.\{1,2\}\$' *

I need to find the MAC address of the ethernet cards on the host machine from the C language. I have found a way to do this on Linux using socket(), ioctl() and the ifreq structure. But this does not seem to work on AIX, HP/UX and probably the others I need (Solaris, SCO, Alpha etc).
Is there a... (7 Replies)
I have a ksh script and would like to validate a MAC address that is input by the user:
00:14:4F:FC:00:49
example:
MAC=`/usr/bin/ckint -p "Enter MAC address"`
echo $MAC
echo " "
Obviously chkint will not work, but does anyone have any suggestions?

I have a .txt file with almost few hundreds interfaces address which need to be changed or mapped to the new interface naming convention. for e.g interface
xe-8/0/0 should be xe-16/0/0
xe-9/0/0 should be xe-17/0/0
it keeps going to xe-31/0/0 which should become xe-55/0/0.

I plan to use a small SPARC Netra T4-1 as a VM server with a primary domain and 2 guest domains. The primary has MPIO configured (4 paths to SAN storage). When a LUN is exported and added to a guest domain, does the single disk server defined on the primary handle the multipathing for the guest... (6 Replies)
Hy over there,
Lets make it simple :)
Using a bash script, how to grep only the ip address and the mac address and put them in a file:.
for example from the dhcp.conf file we got such things:
The script will end up with two columns IP's and MAC adresses as it is showed below:
